Water-soluble and conducting sulfonated polyaniline (SPAN)/phenylamine groups contained MWNTs (p-MWNTs) nano-composite were synthesized by in situ oxidation polymerization followed by sulfonation and hydrolysis. TEM, Raman spectroscopy, FTIR, XPS, TGA and standard four-probe methods were employed to characterize morphology, chemical structure and performance of the nano-composite. The results show that phenylamine groups are grafted on the surface of p-MWNTs via amide bond and oxidized phenylamine groups initiate polyaniline polymerized on the surface of p-MWNTs. SPAN chains covalently attached to p-MWNTs render p-MWNTs compatibility with SPAN matrix and lead to SPAN/p-MWNTs nano-composite highly soluble and stable in water. Improved thermal stability illuminate existence of a new phase in the nano-composite where there is chemical interaction between p-MWNTs and SPAN coatings. Owing to incorporation of p-MWNTs conductivity of the nano-composite at room temperature is increased by about two orders of magnitude over neat SPAN.
