Abstract:

The shape memory process and mechanisms of electro?active shape memory composites were introduced from macro to micro perspectives. The classification and research of electro?active shape memory composites were summarized based on different conductive fillers, including nanoparticles, continuous fibers, short?cut fibers, and composite fillers. The preparation methods including physical compounding, in?situ polymerization, and freeze?drying were analyzed briefly. The electrically induced shape memory composites were introduced according to their conductive mechanisms from three aspects of homogeneous conductor units, interface bonding between conductor and substrate, and conductive network structure. An overview on the phenomena of nanoscale conductive networks and ion channels in the microstructure was presented. Finally, the applications of electro?active shape memory composite materials in aerospace, biomedicine, smart textiles, and electronic semiconductors were discussed and their future development direction was prospected.

Key words: electro?active shape memory property, composite material, nanoparticle, continuous fiber, short?cut fiber, preparation method
