Abstract

In this paper, the functionalized nanosilica was prepared via covalent modification and used as effective nanofillers to reinforce silicone rubber matrix. The influence of functionalized nanosilica on the mechanical property of PVMQ was examined. The microstructures of the nanocomposites were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction. As the nanosilica loading reaches up to 90 wt%, the tensile strength of functionalized nanosilica/PVMQ rubber nanocomposites can reach the maximum values (3.67 MPa). It was noteworthy that the functionalized nanosilica not only could be homogeneously dispersed and incorporated into the polymeric matrix as fillers but also could be effectively improved the mechanical property of the silicone rubber.

功能化纳米二氧化硅改善硅橡胶力学性能的研究

本文通过共价改性法制备了功能化纳米二氧化硅，并将其作为硅橡胶基体的有效纳米填充剂。考察了功能化纳米二氧化硅对PVMQ力学性能的影响。采用傅里叶变换红外光谱、扫描电镜和x射线衍射对复合材料的微观结构进行了表征。当纳米二氧化硅负载达到90 wt%时，功能化纳米二氧化硅/PVMQ橡胶纳米复合材料的抗拉强度达到最大值（3.67 MPa）。值得注意的是，功能化纳米二氧化硅不仅可以均匀分散并作为填料掺入聚合物基体中，而且可以有效地改善硅橡胶的力学性能。

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
