Abstract

The double percolation structure was used to produce thermally conductive polymeric composites including high density poly (methyl methacrylate) (PMMA)/polyethylene (HDPE)/carbon nanofiber (CNF) and polypropylene (PP)/PMMA/boron nitride (BN) composites. Microscopy images showed that for both systems, most of fillers were in PMMA phase, confirming the hypothesis of the filler location by the thermodynamic theory. The thermal conductivity of the PMMA/HDPE/CNF composite was higher than that of the HDPE/CNF and the PMMA/CNF composites with the same content of fillers loading when the CNF concentration got to 16 wt%. In addition, a similar phenomenon was also found when the BN concentration was above 10% in term of the PP/PMMA/BN composites. This study proved that double percolation structure was a useful way to improve the thermal conductivity of the polymer composites.
