摘要
通过DSC考察了成核剂TMC-300对聚乳酸(PLA)成核结晶过程的影响,发现成核剂TMC-300可以有效地促进聚乳酸的成核结晶。在使用Avrami方程对该体系进行评价时发现,该方程只适应于聚乳酸结晶初期的评价,而在后期则出现严重偏离现象。
In this paper, effects of nucleator TMC - 300 on isothermal crystallization behavior of poly （ lactic acid） （PLA）were studied by means of differential scanning calorimetry（DSC）. It was found that the nucleating agent TMC - 300 can effectively promote crystallization of polylactic acid. Avrami equation was used to evaluate the system, it was found that this equation was only suitable for the evaluation of the initial crystallization of polylactic acid,while in the latter, it was a serious deviation from the phenomenon.
