Poly(methacrylic acid-co-methyl methacrylate) (P(MAA-coMMA)) networks were prepared via free radical copolymerization in the presence of linear poly(N-vinyl-2-pyrrolidone) (PVP) and multiwalled carbon nanotubes (MWNTs), i.e., P(MAA-co-MMA)/PVP/ MWNTs nanocomposites. The effect of MWNTs on the thermal and of mechanical properties of P(MAA-co-MMA)/PVP/MWNTs nanocomposites have been investigated. It was found that, MWNTs could provide P(MAA-co-MMA)/PVP/MWNTs nanocomposites with much improved mechanical properties. Thermal analysis showed that a clear improvement of thermal stability for P(MAA-co-MMA)/PVP/MWNTs nanocomposites increased with increasing MWNTs content.
