Аннотация

Natural graphite powder was introduced into a linear low density polyethylene (LLDPE) to improve the thermal conductivity. The thermal conductivity of LLDPE/graphite composites is increased by more than seventeen times with increase in filler content up to 30 vol.% as compared to that of LLDPE matrix. The percolation threshold for these composites is equal to 10 vol.%. LLDPE/graphite composites can be used as cost effective thermally dissipative materials for electrical engineering and electronic devices due to the high thermal conductivity and thermal diffusivity.
