Effects of Polyaniline Doped by Different Acids on Thermal Stability of Epoxy Resin

Abstract:

Article Preview

Polyaniline(PANI) nanofibers were firstly prepared by rapid mixture method, EP/PANI nanocomposite was obtained by in-situ adding the PANI nanofibers to epoxy resin(EP). Scanning electron microscopy(SEM) proves that the type of doped acids has a little effect on the morphologies of PANI, and the PANI doped by different acids present nanofiber structures with the diameter of about 50 nm. The thermal behaviour of EP/PANI nanocomposites were investigated in detail by using a dynamic rate mode of thermogravimetric analyser (TGA) in inert atmosphere, and the results show that the PANI nanofibers obviously improve thermal stability of pure EP. Compared with EP/PANI doped by nitric acid or sulfuric acid, EP/PANI doped by phosphoric acid has best thermal stability.
