Notes:
Conductive polymer composites (CPCs) consisting of expanded graphite (EG), flake-typegraphite (FG) and thermalsetting resin were fabricated by means of a preform molding technique.Conductive fillers, EG and FG, were mechanically mixed with the phenol resin to provide anelectrical property to composites. The filler loadings were fixed at 75wt.% to obtain a high electricalconductivity. The mechanical and electrical properties of CPCs were optimized according to theweight ratio and the particle size of FG. As the weight ratio increased, the flexural strength increased,however, the electrical conductivity decreased for both cases of CPCs using different sizes of FG. Theparticle size was an important parameter to change the mechanical and electrical behaviors. Theflexural strength was sensitive to the particle size due to the different level of densification. Theelectrical conductivity also showed size-dependent behavior because of the different contribution tothe conductive networking
