用差示扫描量热仪(DSC)对PET/石膏晶须复合材料的非等温结晶过程的结晶行为进行了研究,并利用莫氏理论得到了复合材料的动力学参数F(T)和a。F(T)值随着结晶度的增加,逐渐增大;a值几乎相同,近似常数(在1.5~1.8之间)。
The crystallization behavior of non-isothermal crystallization process of PET / gypsum whisker composite was studied by differential scanning calorimeter (DSC). The kinetic parameters F (T) and a of the composite were obtained by using Mönch’s theory. The value of F (T) gradually increases with the increase of crystallinity; the values of a are almost the same and approximate constants (between 1.5 and 1.8).
