Abstract
ABSTRACTA novel method for fabricating flexible and waterproof heating membranes was presented in this study, nano‐SiC/thermoplastic polyurethane (TPU) hybrid membranes has been successfully prepared by pouring modified nano‐SiC/TPU solution into a mold with 0.05 mm silver filaments. Nano‐SiC particles were modified using silane coupling agent, subsequently, were dispersed evenly in the solvent, average diameter of nano‐SiC particles could reach 180.4 nm. Fourier Transform Infrared spectra showed organo‐functional groups were grafted on surface of nano‐SiC by covalent bond. TPU membrane with 10 wt % nano‐SiC had the highest decomposition temperature, and maximum stress. Thermal conductivity and the surface equilibrium temperature under the same loaded voltage of membranes ascended with increasing of nano‐SiC content. Flexible, waterproof nano‐SiC/TPU heating membranes have wide application prospect in active warming garments and other fields required flexible heating elements. © 2014 Wiley Periodicals, Inc. J.
