Properties of electrically actuated shape memory polymer composites reinforced by buckypaper
摘要
Abstract
In order to study the effect of few-layer graphene ( FLG) and carbon nanofiber ( CNF) on the electrical conductivity of mixed FLG/CNF buckypaper, the volume resistivity of buckypaper was measured as the quality ratio of FLG/CNF increased from 0 to 50%. The microcosmic morphology of FLG/CNF buckypaper was observed using a scanning electron microscope. The electrical actuation and the temperature distribution of the shape memory polymer ( SMP ) composites reinforced by FLG/CNF buckypaper were also tested. The results show that CNF bridged the gaps between the FLG layers, and an entangled and continuous network of FLG and CNF is observed. Furthermore, the ratio changes between FLG and CNF in the buckypaper can lead to change in the electrical resistivity of the buckypaper. The shape recovery of SMP composites reinforced by buckypaper is completed at about 90 s. The re-covered shape of the specimen is approximately 95% similar to its original shape.关键词
