Abstract

This document explains and demonstrates how to prepare Polyurethane(PU)/Expanded Graphite powder(EGp) composite antistatic sponge by in situ polymerization. The morphology、mechanical、electrical and thermal properties of the PU/EGp composite antistatic sponge have been investigated. PU/ EGp composite sponge have better mechanical properties than that of CB composite. The resistivity of PU/EGp composite antistatic sponge can reach at about 108Ω•cm at the content around 5wt% of the EGp. EGp can stably exist in PU sponge and has little influence to the polymeric matrix while being heated.
