| Summary: | Thermally conductive polymer composites offer new potentials for replacing metal parts in numerous applications,
including power electronics, electric motors and generators, heat exchangers, and so on. Current interest to enhance
the thermal conductivity of polymers is focused on the selective addition of nanofillers with high thermal conductivity.
Therefore, graphene is the best choice material for thermally conductive composite. This study focuses on conducting
the experiment to measure the thermal conductivity of graphene based epoxy nanocomposites with various variables
and preparation conditions. Along this project, a series of experiment is done by manipulating the graphene loading
ratio, the stirring rate, and the stirring time. 34 samples were prepared, tested, and analysed in order to determine the
composite samples with the optimum variables. At the end of the experiment, the highest thermal conductivity of
graphene based epoxy nanocomposites is identified at 0.204 W/mK. The optimum variables and conditions that came
out with the best result are 0.3 wt% of graphene loading and 500 rpm of stirring rate at 30 minutes of stirring time. The
enhancement of the thermal conductivity is 19.53% higher than that of the neat epoxy alone which is 0.17067 W/mK.
This project is expected to serve as a good reference for future studies. |
