Abstract: Polyamide 11/graphene oxide (PA11/GO) nanocomposites were prepared via in-situ polymerization. Non-isothermal crystallization and melting behaviors of PA11 and PA11/GO nanocomposites were investigated using differential scanning calorimetry, and Non-isothermal crystallization kinetics of them was analyzed by Jeziorny and Mo method. It was found that both PA11 and PA11/GO nanocomposites displayed double melting peaks. The addition of GO decreased the crystallization rate of PA11. The mechanisms of nucleation and growth of crystallization were changed by adding GO.

Key words: polyamide 11, graphene oxide, in-situ polymerization, non-isothermal crystallization kinetics, melting behavior
