Step Polymerization

Biobased shape memory polyurethane filled with carbon nanotubes (CNT) were prepared using two step polymerization process. The bio based shape memory polyurethane (SMPU) were composed of polycaprolactonediol, polyol based on palm oil, 4, 4’-diphenylmethane diisocyanate and 1, 4-butanediol. In this paper, CNTs has been used as fillers to introduce the electrical conductivity in the SMPU. The bio-based shape memory polyurethane shows electrical conductivity with addition of 7 wt% CNT.
