摘要：
Single and multilayered nanocomposites of polyaniline (PANI), polypyrrole (PPy), Epoxy, polystyrene (PS) and functionalized carbon nanotubes (MWCNT) have been synthesized as PANI/MWCNTs, PPy/MWCNTs, Epoxy/MWCNTs, PS/MWCNTs, PANI/PPy/MWCNTs, PANI/PPy/Epoxy/MWCNTs and PANI/PPy/Epoxy/PS/MWCNTs. Layering of matrices on filler surface through layer-by-layer oxidative polymerization was confirmed by Fourier transform infrared spectroscopy. According to SEM, doubly layered PANI/PPy/MWCNTs revealed finely dispersed granular layer of polypyrrole over the surface of polyaniline. Thermogravimetric analysis of multilayered PANI/PPy/Epoxy/PS/MWCNTs showed degradation at enhanced temperature 400-750 degrees C and char yield 45% at 900 degrees C. Improvement in glass transition of layered material was observed from 275 degrees C (PANI/PPyMWCNTs) -354 degrees C (PANI/PPy/Epoxy/PS/MWCNTs).
