| 摘 要： | 采用火焰喷涂法制备了聚酰胺12（PA12）及PA12/纳米SiO2复合涂层,利用差示扫描量热法（DSC）对PA12及其复合涂层的非等温结晶性能进行了分析,对所得的数据分别用Jeziorny法和Mo法进行处理。结果表明：用Jeziorny法和Mo法处理PA12及其复合涂层的非等温结晶过程比较理想；用Jeziorny法求出的Zc（结晶速率常数）和n（Avrami指数）均随冷却速率的增加而增加;而纳米SiO2的加入使复合涂层的Zc和n均大于纯PA12涂层，且使结晶半衰期缩短、结晶速率及结晶度增大。表明纳米SiO2具有明显的成核剂作用。

| Abstract: | Coatings of polyamide 12(PA12)and its composites with nanometer-sized silica(nano-SiO2)were prepared by a flame spraying process.The non-isothermal crystallization behaviors of the coatings were investigated by differential scanning calorimetry(DSC).The DSC data for non-isothermal crystallization were analyzed by the Jeziorny and the Mo models.The result indicated that both the Jeziorny and the Mo methods can be successfully used to describe the non-isothermal crystallization behaviors of flame-sprayed PA12... |
