A New Kind of Silica Microspheres Used as Filler for PDMS Composite

Article Preview

Abstract:

A new kind of silica microspheres were first synthesized with dodecyltrimethoxysilane (WD10) and tetraethoxysilane (TEOS) by sol-gel method. And hybrid membrane was prepared by incorporating the as prepared filler into polydimethylsiloxane (PDMS). Thermal degradation and mechanical properties of these composites membranes were studied by means of thermogravimetric analysis and tensile testing. The experimental results showed that both mechanical properties and thermal stabilities of these composites were significantly improved by using the as-synthesized filler.
