Synergistic effect of self-assembled carbon nanopaper and multi-layered interface on shape memory nanocomposite for high speed electrical actuation

Abstract

The synergistic effect of self-assembled carbon nanofiber (CNF) nanopaper and the multi-layered interface on the electrical properties and electro-activated recovery behavior of shape memory polymer (SMP) nanocomposites is investigated. The CNFs were self-assembled by deposition into sheets of multi-layered nanopaper form to significantly enhance the bonding strength between the nanopaper and SMP via van der Waals force. The self-assembled multi-layered CNF nanopaper resulted in improved electrical conductivity and temperature distribution in the SMP nanocomposites. This not only significantly enhances the reliability of bonding between the nanopaper and the SMP, resulting in an improved recovery ratio, but also provides high speed electrical actuation. V

Effects of immersion duration and temperature on mechanical properties of optical fibers aged in CTAC aqueous solution

“…Lu et al [20] have examined the synergistic effect of selfassembled carbon nanofiber (CNF) nanopaper and multi-layered interface on the electrical property and electro-activated recovery behavior of shape memory polymers nanocomposites. The surfactant Triton X-100 was used to aid the dispersion of CNF.…”

Controlling Au electrode patterns for simultaneously monitoring electrical actuation and shape recovery in shape memory polymer

“…Electrical actuation of the SMP can be achieved at a low voltage of 10.0 V [25,28,37,38]. The conductive ingredients could also improve the thermal conductivity of the SMP matrix to achieve a fast response [26,31,39,40]. This electrically induced SME is especially useful for applications where direct heating is impossible such as in selfdeployable aerospace structures [41], implanted biomedical devices [42,43], micro-actuators and sensors [44e46].…”
