| Abstract: | Silica/MC nylon6 in situ nanocomposites was obtained through anionic ring-opening polymerization. The non-isothermal crystallization of MC nylon6 and its nanocomposites was investigated by means of differential scanning calorimetry(DSC). Results showed that the corresponding crystallization kinetics could be described by the modified Avrami theories(Jeziorny and Liu methods) very well, the introduction of nano silica which acted as nuclei increased the crystallization rates of MC nylon6 matrix. |
