Multiphase Composites

Selective dispersion of carbon black (CB) in three kinds of epoxy resin (EP)/ thermoplastic multiphase conductive polymer composites were investigated. The thermoplastics involved polystyrene (PS), polyethersulfone (PES) and polyetherimide (PEI). The results showed that the selective location of CB particles are mainly controlled by thermodynamics as indicated by consistency of wetting coefficient prediction and real microstructure. For CB/EP/PS, with co-continuous phase structure, CB particles are not selectively located in one polymer but located in both EP-rich phase and PS-rich phase. For CB/EP/PES, with not perfect inverted phase structure, CB particles are selectively located in PES-rich phase. For CB/EP/PEI, with perfect inverted phase structure, CB particles are selectively located in PEI-rich phase.
