摘要
采用原位聚合法制备了聚酰胺11/石墨烯氧化物(PA11/GO)纳米复合材料,利用差示扫描量热仪研究了PA11和PA11/GO纳米复合材料的非等温结晶过程和熔融行为,并通过Jeziorny法和Mo法研究了PA11及其复合材料的非等温结晶动力学。结果表明,PA11和PA11/GO纳米复合材料均呈现双重熔融峰。GO的加入抑制了PA11的结晶行为,降低了结晶速率。GO会影响PA11的成核和晶体生长规律。
Polyamide 11/graphene oxide (PA11/GO) nanocomposites were prepared via in-situ polymeri- zation. Non-isothermal crystallization and melting behaviors of PAll and PA11/GO nanocomposites were investigated using differential scanning calorimetry, and Non-isothermal crystallization kinetics of them was analyzed by Jeziorny and Mo method. It was found that both PAll and PA11/GO nanocomposites displayed double melting peaks. The addition of GO decreased the crystallization rate of PA11. The mechanisms of nucleation and growth of crystallization were changed by adding GO.
