A spatially and temporally controlled shape memory process for electrically conductive polymer–carbon nanotube composites

Abstract

Crosslinked P(MMA-BA)–CNTs shape memory composites prepared by ultrasound assisted in situ polymerization, have both relatively high electrical conductivities and good shape memory properties. Electrical resistance heating was used as a trigger to realize the spatial and temporal control of the shape memory process and to obtain multiple shapes by selecting the place where the electrical voltage was applied or switching the power on/off.
