PA11/SiC复合材料非等温结晶动力学研究
Study on Non-isothermal Crystallization Kinetics of PA11/SiC
摘要
Abstract
Polyamide11/silicon carbide (PA11/SiC) composites were prepared by melt-blending method.The nonisothermal crystallization behaviors of the composites were investigated by differential scanning calorimetry (DSC).Moreover,its non-isothermal crystallization kinetics was studied by Jeziorny and Mo methods,and correlative non-isothermal crystallization kinetic parameters were obtained.The results show that both the above equation can describe the nonisothermal crystallization of PA11 and PA11/SiC composites well.The non-isothermal crystallization kinetics parameters from Jeziorny and Mo methods both show that the addition of SiC can affect the non-isothermal crystallization behaviors of PA11/SiC composites,the nucleation and crystal growth of the composites could be promoted by adding 1％ SiC,and so does the crystallization rate of the composites.In addition,it' s known by Jeziorny method that there are two stage in the non-isothermal crystallization of PA11 and PA11/SiC composites,the primary crystallization stage and the secondary crystallization stage.The crystal forms of the secondary crystallization stage are one-dimensional linear,two-dimensional disk-shaped and three-dimensional spherulite growth coexisting.关键词
