摘要

To improve the thermal and mechanical properties of liquid silicone rubber (LSR) for application, the graphene oxide (GO) was proposed to reinforce the LSR. The GO was functionalized with triethoxyvinylsilane (TEVS) by dehydration reaction to improve the dispersion and compatibility in the matrix. The structure of the functionalized graphene oxide (TEVS-GO) was evaluated by Thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectra, X-ray diffraction (XRD), and energy dispersive X-ray spectroscopy (EDX). It was found that the TEVS was successfully grafted on the surface of GO. The TEVS-GO/LSR composites were prepared via in situ polymerization. The structure of the composites was verified by FTIR, XRD, and scanning electron microscopy (SEM). The thermal properties of the composites were characterized by TGA and thermal conductivity. The results showed that the 10% weight loss temperature (T-10) increased 16.0 degrees C with only 0.3 wt % addition of TEVS-GO and the thermal conductivity possessed a two-fold increase, compared to the pure LSR. Furthermore, the mechanical properties were studied and results revealed that the TEVS-GO/LSR composites with 0.3 wt % TEVS-GO displayed a 2.3-fold increase in tensile strength, a 2.79-fold enhancement in tear strength, and a 1.97-fold reinforcement in shear strength compared with the neat LSR.
