Enhanced thermal conductivity of polyethylene/boron nitride multilayer sheets through annealing

Polyethylene/hexagonal boron nitride (PE/h-BN) composite sheets with enhanced thermal conductivity were fabricated through annealing a multilayered structure of alternating high density PE (HDPE)/h-BN composite and low density PE (LDPE) layers. Multilayer sheets possess a relatively low initial content filler, and after thermal annealing at 200 °C, the PE molecules in the composite layers diffused into neighboring layers. As a result, the h-BN...
