摘要
采用示差扫描量热仪(DSC)研究了具有生物相容性及可降解性P(BHB-CL)超支化共聚酯的非等温熔融结晶过程,分别采用Avrami方程、Ozawa方程和Mo方程对P(BHB-CL)共聚酯的非等温动力学数据进行比较分析,计算了相关的非等温结晶动力学参数,并利用Kissinger方程计算其非等温结晶活化能.结果表明,Mo方程更适合描述P(BHB-CL)共聚酯的非等温结晶过程.
The nonisothermal crystallization behavior of biocompatible and biodegradable polyester P(BHB-CL) was investigated via differential scanning calorimetry(DSC).Avrami equation,Ozawa approach,and Mo approach were adopted to study the nonisothermal crystallization of P(BHB-CL),and activation energy value of P(BHB-CL) was determined according to the Kissenger method.The results show that Mo approach can be successfully applied to analyze the nonisothermal crystallization process of P(BHB-CL).
