Abstract: Low-temperature expandable graphite (LTEG) was blended into low-density polyethylene (LDPE) to prepare composite materials with an enhanced thermal conductivity in comparison to pure LDPE. The thermal conductivity of a composite containing 60 wt. % LTEG was found to be increased by a factor of 23 in comparison to the pure polymer. The LTEG was also found to decrease the melting temperature and degree of crystallinity of the LDPE, and the composites were also found to be more thermally stable.
