The purpose of this work is to solve the problem of interface bonding in aluminum foam (AF)/polyoxymethylene (POM) interpenetrating phase composites (AF/POM). Silane coupling agent (KH-550), graphene oxide (GO), sulfonated graphene (S-GNS) and graphene (GS) coatings were prepared on the surface of AF, respectively, as an interfacial transition layer. The molten modified POM(POMC) was injected into the hole of coated AF by injection molding to prepare different kinds of coated AF/POMC. Thermal conductivity, friction coefficient and wear loss of ...
