Abstract: Poly(methyl methacrylate) (PMMA)/Ianthanum hydroxide (La(OH)3) nanowire nanocomposites were prepared by in-situ polymerization of methyl methacrylate (MMA) in the DMF solution. The improvement in thermal stability of the nanocomposites is remarkable with low inorganic nanowires content. The experimental results indicate ultimate network formation for the nanocomposites is possibly through interaction between La3+ and MMA monomer during polymerization. The network induces the mobility restriction of polymer chains and greatly prevents polymer chains from decomposition. The characteristic of one-dimensional nanowires used here may play a key role in the formation of the "cross-link" network and decision of the low content of nanowires addition in the polymer matrix.
