Characterization of Silica-PAN Composite Nanofibers

The advantages of polymer materials such as high strength, good mold ability and flexibility could be combined with the great properties of inorganic materials such as high strength,heat strength, heat stability and chemical resistance through producing composite materials [1-3]. The wide rangeapplications of nanofibers could be extended with enhancing their mechanicaland thermal properties by incorporating inorganic nanoparticles in their structures [4,5]. Due to theimproved mechanical, electrochemical and heat stability properties of silica filled composite nanofibers, they haveattracted much interest in recent years [6]. This paper characterized the chemical structure and thermal behavior of Silica-PAN composite nanofibers containing various ratios of silica nanoparticles with diameter of 10 and 80 nm.
