Abstract:

The MC nylon 6/ZnO nanocomposite was prepared by using the in-situ polymerizing reaction, and its isothermal crystallization behavior was studied by the differential scanning calorimetry(DSC). The results show that the crystallization rate of both MC

nylon 6 and MC nylon 6/ZnO nanocomposite are controlled by the nucleating process at 188 ℃ to 196 ℃. As compared to MC nylon 6, the crystallization rate G of MC nylon 6/ZnO nanocomposite increases 0.1~0.3 min-1. It is found that the increase of the crystallization rate of MC nylon 6 due to the nano-sized ZnO was used as the heterophase crystal nucleating agents. For both MC nylon 6 and MC nylon 6/ZnO nanocomposite, with increasing the crystallization temperature, the crystallization rate G and its constant k is decreased, the time t1/2 of the half crystallization and that tmax of the maximum crystallization rate is shortened. However, for comparison with MC nylon 6, the decrease content is more obvious for MC nylon 6/ZnO nanocomposite.
