    Hybrid fibre which is rice husk (RH) and softwood were used as organic fibre with different compositions which are 10%, 20% and 30%. Whereas polymer matrix that used in this project is recycled high density polyethylene (r-HDPE) and ethylene glycidyl methacrylate (EGMA) used as compatibilizer in the composite. These materials were pre-mixed using a twin screw extruder and then shaped using hot compression in order to obtain a dumbbell and rectangular shape for Izod impact test, tensile and flexural test using Instron machine. Another test was carried out with a focus to observe the behaviour of water absorption in the composite. Testing resulted in decreasing tensile strength, elongation at break and impact stress upon an increase of fibre content. However, there are slight increases in the result of Young's modulus, water absorption, flexural strength and modulus.

    This study compares the mechanical properties of recycled high-density polyethylene (r-HDPE)/rice husk (RH) composites from a twin-screw extruder and a heated two-roll mill, and the effect of different filler loadings using different melt blending processes on the mechanical properties of r-HDPE/RH composites. Polyethylene-graft-maleic anhydride (MAPE) acts as the coupling agent to enhance interfacial bonding between the fibre and the polymer matrix. The filler loading used was in the range of 10-40 wt. %. In this work, r-HDPE/RH blends were prepared using a twin-screw extruder and a heated two-roll mill. The ratio of 70/30 twin-screw extruder compounded composites significantly showed higher tensile based on improved to about 45.5% at 11 MPa compared to those compounded in the heated two-roll mill. The same ratio showed an increment almost up to 9% of elongation at break. It has also been verified that the higher filler loading used reduced the tensile strength and elongation at break, while the Young's modulus increased. The result was evidenced by the increase in water absorption and longer burning time as the filler loading increased.

    Degree of acetylation (DA) is an important parameter to determine the quality of chitin. Apart from the assessment on the bond structure in the chitin molecule, infrared spectroscopy is one of the methods that can be used to determine the value of DA. The DA value of chitin is an important parameter because the value indicates the purity of chitin quality. Chitin acetylation is the process of addition an acetyl substitution group (-COCH3) to a chitin chain. The addition of acetyl will improve its dispersing properties and subsequently will improve the chitin adhesion properties within hydrophobic matrix in composite materials as well. In this study, Deep Eutectic Solvent (DES) was used as a medium for chitin extraction and acetylation in one single process. DES has two components namely Hydrogen Bond Donor (HBD) and Hydrogen Bond Acceptor (HBA). Betaine and choline chloride were used as HBA whilst urea was selected to be utilized as HBD. The findings showed that the quantity of extracted chitins by the DESs were 5.4609 % and 2.0020 % respectively. The DA values for the extracted chitins are 103.1699 and 83.4821. For acetylated chitin in DES betaine - urea, the DA value was increased from 103.1699 to 118.4818. The findings showed that the high quality acetylated chitin can be produced in a single process involving extraction and acetylation process by using DES as a medium.

    The purpose of this project is to extract Microcrystalline Cellulose (MCC) from Banana fiber to produce Poly(Lactic Acid)/Microcrystalline Cellulose, (PLA/MCC) biocomposite film using a solvent casting technique. The initial phase is the production of MCC from Banana fiber by involving three steps; alkaline treatment, bleaching and acid hydrolysis. MCC produced from the different concentration of Nitric acid in the acid hydrolysis process, were used to analyze the morphological and crystalline properties using SEM and XRD respectively. MCC produced from the higher concentration of Nitric acid shows good morphological properties and higher % crystallinity. Then, MCC compounded into PLA with different filler loading to produce PLA/MCC biocomposite film using a different solvent which is Chloroform and Dichloromethane. Results show that lower MCC loading, induces good filler matrix interaction and this evidences by the improvement of the Tensile strength and Young's Modulus, as well as shows improvement in loss factor and storage modulus which studied from DMA. Moreover, the addition of MCC slightly improved the thermal stability of PLA. From using a different solvent to produce PLA/MCC biocomposite film, Dichloromethane solvent improves the tensile strength and Young's modulus of biocomposite film, while Chloroform reduces the tensile properties of biocomposite film.

    The conventional method to extract the chitin content from the crustacean shells usually uses concentrated acids and alkalis to remove impurities such as calcium carbonate and protein. However, the uses of concentrated acids and alkalis have caused many environmental issues. Deep Eutectic Solvent (DES) is one of the solvents that can be used to extract the chitin content from the crustacean shells. DES has two components namely Hydrogen Bond Donor (HBD) and Hydrogen Bond Acceptor (HBA). In this study, two types of DES have been used are betaine (HBA) - urea (HBD) and choline chloride (HBA) - urea (HBD). The results showed that DES betaine - urea and choline chloride - urea have extracted chitin content of 5.4609 % and 2.0020 % w/w respectively. The extracted chitins were analyzed using infrared spectroscopy method. The values of the degree of acetylation (DA) for the chitins were 103.1699 and 83.4821 respectively.

    The demand for natural fiber hybrid composites for various applications has increased, which is leading to more research being conducted on natural fiber hybrid composites due to their promising mechanical properties. However, the incompatibility of natural fiber with polymer matrix limits the performance of the natural fiber hybrid composite. In this research work, the mechanical properties and fiber-to-matrix interfacial adhesion were investigated. The efficiency of methyl methacrylate (MMA)-esterification treatments on composites’ final product performance was determined. The composite was prepared using the hand lay-up method with varying kenaf bast fiber (KBF) contents of 10, 15, 20, 25, 30, 35 (weight%) and hybridized with glass fiber (GF) at 5 and 10 (weight%). Unsaturated polyester (UPE) resin and methyl ethyl ketone peroxide (MEKP) were used as binders and catalysts, respectively. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) were used to examine the effects of MMA-esterification treatment on tensile strength and morphology (tensile fracture and characterization of MMA-esterification treatment) of the composite fabricated. The tensile strength of MMA-treated reinforced UPE and hybrid composites are higher than that of untreated composites. As for MMA treatment, 90 min of treatment showed the highest weight percent gain (WPG) and tensile strength of KBF-reinforced UPE composites. It can be concluded that the esterification of MMA on the KBF can lead to better mechanical properties and adhesion between the KFB and the UPE matrix. This research provides a clear reference for developing hybrid natural fibers, thus contributing to the current field of knowledge related to GF composites, specifically in transportation diligences due to their properties of being lightweight, superior, and involving low production cost.

    Over the years, the extrusion technique has captured the attention of polymer industries by meeting the demand for polymer processing and fabrication of final products. Extrusion is a continuous process, and it has a lot of potential in the increasing polymer sector, especially in the three-dimensional (3D) printing sector. 3D printing is popular because the feedstock filament form is accessible and produce able. The properties of the filament used influence the printed part qualities regardless of the FDM parameters. This study provides information on how extrusion parameters affect the diameter of extruded filaments. This study reviews previous studies on the effect of varied extrusion settings on filament diameter. The review will serve as a resource for researchers in the 3D printing sector to fabricate their filaments for 3D printing. Overall, this paper will provide solutions to overcome issues in obtaining optimal filament diameters for future research projects.

    The goal of this study was to investigate the effect of surface treatment on rice husk reinforced recycled high density polyethylene (rHDPE) composites. Three types of surface treatments on rice husk were carried out which were maleated treatment, alkali treatment and acrylic acid treatment. Water absorption test was examined in distilled water. It showed that the lower the loading of rice husk, the lower the water absorption percentage. Maleated treatment on rice husk reinforced rHDPE has the highest resistance of water absorption tendency. Scanning electron microscope analysis of the composites showed that the lower the rice husk loading, the better the interfacial bonding of the composites. Maleated treatment of rice husk also showed that there is no gaps formed in the structure.

    Treating and cleaning corroded artefact has resulted in long-term loss of artefact integrity and intangible historical value in museum preservation method. Inhibitors and coatings are preferable methods applied in heritage conservation as it is the easiest way for corrosion protection. However, issue of health and environment has led conservators to find a better inhibitor, natural or green corrosion inhibitors. Surprisingly, Malay traditional practice has since long ago used Coconut water (CW) as corrosion inhibitor to preserve keris blades, showing that the knowledge in corrosion protection has been practiced in old Malay civilization for metal preservation. This paper intends to clarify the compositional effect of CW in the inhibition efficiency to iron-based keris blade. Through Tafel and Electrochemical Impedance Spectroscopy (EIS) and Energy dispersive analysis of X-rays (EDAX) analysis, the study showed that CW formed passivation with the highest IE of 92% as compared to other natural inhibitors existing and used in industries such as Ascorbic Acid (AA) and Tartaric acid (TA). EIS and Scanning Electron Microscope (SEM) study has shown and conclude that CW has displayed protective abilities that exceeds both AA and TA.
