ABSTRACT

Emerging thermal dissipation of many electronic devices, i.e. light emitting diodes, energy storage components, CPU chips etc. as well as in many emergent new applications (smart textile, self-assembling materials, etc.) is a great challenge. The reliance of thermal conductivity of composites on the filler loading, filler networking morphology and on the whole composite structure is also discussed. This work is intended to design composites for the improvement of thermal conductivity of polypropylene and ethylene-vinyl acetate copolymer with lower filler contents. As filler both organic (activated carbon) and inorganic (alumina) materials alone or in a combination of various relative proportions have been used. An internal blending unit was used for melting the copolymer and proper mixing the filler particles with the molten matrix. Final composites were made by the hot press. Then Lee's Disc apparatus was used to measure the thermal conductivity of various composite samples by steady-state method. Experimental results show that only carbon black addition was not adequate to increase the thermal conductivity of the composites to expected level. The experimental value compare with some theoretical model to describe the prediction value accuracy for such multiphase composite. However, addition of small amount of alumina powder with carbon black significantly increased the copolymer composites.
