Abstract
The measurement of low-density polyethylene / thermoplastic starch (LDPE/TPS) composite with different loading of calcium carbonate (CaCO3) as filler was conducted under several testing such as the tensile test and scanning electron microscopy. The preparation of LDPE/TPS/CaCO3 composite was divided into three stages. The first stage involved the preparation of TPS with and without modification with carboxylic acid. The second stage, LDPE was blended with TPS to produce LDPE/TPS blend. LDPE/TPS blends with blend ratio of 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 was prepared. Each composition will undergo tensile testing to analyze their mechanical properties. The optimum LDPE/TPS blend ratio was chosen for subsequent study. Third stage involved the compounding of the chosen LDPE/TPS blend ratio with CaCO3. The result indicate that LDPE/TPS with incorporation of CaCO3 gave higher value of tensile properties as compared to LDPE/TPS blend. Based on the SEM micrograph, treated TPS with citric acid and ascorbic acid performed better interfacial phase as compared to untreated TPS, with no agglomeration and voids formation.
