The Synthesis of Electrically Actuated Shape Memory Polymer Composites Reinforced by Nanopaper

Abstract:

A method of synthesizing the FLG/CNF nanopaper on hydrophilic polycarbonate membrane was investigated. The synergistic effect of few-layer graphene (FLG) and carbon nanofiber (CNF) on the electrical conductivity of shape-memory polymer (SMP) composites reinforced by the FLG/CNF nanopaper was explored. The conductive FLG/CNF nanopaper facilitates the actuation in SMP composite induced by electrically resistive heating. The heat conduction in a nanopaper depends greatly on FLG/CNF network formation. The morphology and structure of the FLG/CNF nanopaper are characterized with scanning electronic microscopy (SEM). The flat surface and tunable network structures observed from the microscopic images indicate that the FLG/CNF nanopaper could have highly conductive property. Detailed structural characterization indicates that the three-dimensional networks of nanopaper, result in both the reduction of thermal contact resistance and the enhancement of conductive property along the thickness.
