Fabrication and Characterization of Chemical Vapor-actuated PANI/PU Bilayer
摘要
Abstract
Polyaniline(PANI) and its derives have emerged as a group of most promising organic conducting polymers due to its iow cost, easy preparation, excellent environmental stability, facile redox and pH switching behavior. Particularly, its response to electrochemical and chemical doping-dedoping process, can produce changes in conductivity, color volume, and so forth, they have been widely used in a variety of nonvolatile memory, chemical sensors, actuators, and so on. Polyaniline/polyurethane(PANI/PU) bilayer actuators were fabricated using PAN1 nanofibers as active material and electrospun polyurethane(PU) fibers as substrate. It was found that the PANI/PU bilayer actuators underwent bending-recovery movement induced by hydrochloride vapor. The deformation mechanism of the bilayer actuators might result from asymmetric volume expansion/contraction because of doping/dedoping and sorption/desorption of chemical vapors. Moreover, the PANI/PU bilayer actuator could carry over 9 times its own weight due to the high toughness of PU fibers, displaying the well load-bearing capacity. Because the PANI/PU actuator is ultra-lightweight, low cost and simple operation,it is advantageous for practical applications in the future. However, actuating performance of the bilayer like lifetime, deformability still need to be improved.关键词
