利用DSC测试了MRPA66,MFPET和MFPP三种云母填充的高子分复合材料在六种冷却速率下的非等温结晶DSC曲线.根据Ozawa方程,利用作者新编的“高聚物结晶动力学数据处理程序包”,处理了所得的DSC曲线,结果表明:MFPET和MFPP的非等温结晶过程是遵从Ozawa方程的,但在MRPA66的场合中,Ozawa理论已不适用. 本文首次利用Ozawa理论报导了MFRET和MFPP三种高分子复合材料六类样品的表观结晶活化能等非等温结晶动力学参数.实验结果还表明:当冷却速率小等于5K/分时,与成核效应及晶体生长维数有关的Ozawa指数只随结晶温度的改变略有变化;但当冷却速率大等于8K/分时,Ozawa指数将随结晶温度升高而迅速变大,此时已不宜用Ozawa方程来处理非等温结晶数据.
The non-isothermal crystallization DSC curves of three mica-filled high sub-sub-composites with MRPA66, MFPET and MFPP at six cooling rates were tested by DSC. According to the Ozawa equation, the authors newly edited “Polymer Crystallization Kinetics Data Processing Package ”and processed the DSC curves. The results show that the non-isothermal crystallization process of MFPET and MFPP obeys the Ozawa equation, but the Ozawa theory is not suitable for MRPA 66. The paper first reports on MFRET MFPP three kinds of polymer composites six kinds of samples such as apparent crystallization activation energy and other non-isothermal crystallization kinetics parameters.The experimental results also show that: when the cooling rate is equal to 5K / min, and the nucleation effect and crystal growth dimension The Ozawa index changes only slightly with the change of the crystallization temperature. However, when the cooling rate is larger than 8K / min, the Ozawa index will increase rapidly with the increase of the crystallization temperature. Therefore, Ozawa equation should not be used to deal with the non-isothermal crystallization data.
