Functional Properties of Polyurethane-Shape Memory Polymer

Hisaaki TOBUSHI, S. Hayashi, K. Okumura, Masamori Endo

Abstract

The main functional properties of shape memory polymer are shape fixity and shape recovery. Gas permeability is also observed in polyurethane-shape memory polymer. Shape memory polymer is light, shows large deformation and is easy to be formed. The glass transition temperature of shape memory polymer can be set around the room temperature. Shape memory polymer is expected to be applied as an intelligent material.
