Abstract
The study on poly(tetrafluoroethylene) (PTFE) reinforced with tetraethoxysilanes (TEOS) derived SiO 2 was described. The study included the manufacturing process of SiO 2 reinforced PTFE and the effects of silylation agent on the properties of the hybrid materials. PTFE/SiO 2 hybrids of 50 wt % SiO 2 loading were prepared via sol-gel process and were shaped by a two roll milling machine. It was found that the surface modification of PTFE/SiO 2 by silylation was an effective technique in tailoring PTFE/SiO 2 materials for low D k components and substrate applications.
