Electric Heating Recovery Performance of Shape Memory Polymer Based on Embedded Buckypaper

Shape memory polymer (SMP) is a kind of smart material, which can remember its original shape actuating by temperature. Comparing to shape memory alloy, SMPs have large actuating deformation, low density and are convenient to fabrication. Because the shape and stiffness of SMP are responsible to the temperature, Heating is the only actuating method to recovery of SMP. This paper proposed a kind of electric heating method to actuate SMP with embedded buck paper. The SEM, heating, shape recovery experimental test proved that, good bonding was formed between buck paper and SMP, uniformly distributing heating temperature and quickly SMP shape recovery.
