AbstractThe kinetics of isothermal crystallization of nylon 6/montmorillonite nanocomposites with different content of montmorillonite prepared by melt intercalation process has been investigated by DSC. It is shown that the presence of nanometer montmorillonite particles displays a high propensity to nucleate Nylon 6 crystallization, enhance the crystallization rate of Nylon 6, reduce the surface free energies of the developing crystals and improve the behavior of isothermal crystallization of Nylon 6 dealt with the Avrami and Hoffman theories. The crystallization process of Nylon 6 is composed of two stages:the spherulite growth stage and the spherulite nucleation stage. With the increment of the clay content in the Nylon 6/montmorillonite nanoconposites, the crystallization rate parameter k decreases and the surface free energy of the Nylon 6 crystals increases; the spherulite growth stage would become the main stage of the crystallization process in place of the spherulite nucleation stage.
