Thermal interface material (TIM) had been well conducted and developed by using several material as based material. A lot of combination and mixed material were used to increase thermal properties of TIM. Combination between materials for examples carbon nano tubes (CNT) and epoxy had had been used before but the significant of the studied are not exactly like predicted. In this studied, thermal interface material using graphene and CNT as main material were used to increase thermal conductivity and thermal contact resistance. These two types of TIM had been compare to each other in order to find wich material were able to increase the thermal conductivity better. The sample that contain 20 wt. %, 40 wt. % and 60 wt. % of graphene and CNT were used in this studied. The thermal conductivity of thermal interface material is both measured and it was found that TIM made of graphene had better thermal conductivity than CNT. The highest thermal conductivity is 23.2 W/ (mK) with 60 w. % graphene meanwhile at 60 w. % of CNT only produce 12.2 W/ (mK thermal conductivity).

Thermal interface material (TIM) had been well conducted and developed by using several material as based material. A lot of combination and mixed material were used to increase thermal properties of TIM. Graphene prove to be one of the best material that have highest thermal conductivity in the world. In this studied, the effect of graphene as based material was used to increase thermal conductivity in thermal interface material. The sample that contain varies weight ratio of graphene were used in this studied. The thermal conductivity of thermal interface material is both measured and it was found that the higher wt. % of graphene can increase higher thermal conductivity. The highest thermal conductivity is 21.6 W/ (mK) with 50 wt. % graphene meanwhile at 10 wt. % of graphene can only produce 5.4 W/ (mK thermal conductivity).
