| 摘 要： | 利用差示扫描量热仪,Avrami方程和Hoffman-Weeks理论,研究了不同结晶温度下,尼龙11/空心玻璃微珠(PA11/HGB)复合材料的等温结晶和其熔融行为。结果表明,Avrami方程能够较好地描述复合材料PA11/HGB的等温结晶动力学;且材料随温度的升高,结晶速率呈逐渐降低趋势,HGB在复合材料起到成核剂的作用。

| Abstract: | The isothermal crystallization and melting behavior of Nylon 11/hollow glass bead (PA11/HGB) composite at different crystallization temperature was studied by using Avrami equation and Hoffman-Weeks theory and differential scanning calorimetry. The results show that the isothermal crystallization kinetics of PA11/HGB composite can be well described with Avrami equation. The isothermal crystallization rate of PA11/HGB composite show a trend of gradually reduce with the temperature increase. HGB play a role of nucleating agent in PA11/HGB composite. |
