热塑性聚酰亚胺与聚醚醚酮共混物的等温结晶动力学
Isothermal Crystallization Kinetics of Thermoplastic Polyimide and Poly ( ether ether ketone) Blends
摘要
Abstract
Thermoplastic polyimide ( TPI) and poly ( ether ether ketone ) ( PEEK ) blends were prepared by melt blending and the isothermal crystallization kinetics of the blends was investigated by differential scanning calorimetry ( DSC ). Avrami equation and Hoffman-Lauritzen equation were used to analyse the isothermal crystallization kinetics, folding-surface free energy(ere) and the work of chain folding(q) , respectively. The results showed that the rate of crystallization of PEEK decreased, while activation energy of crystallization, σc and q increased when TPI was added. But there was no linear relationships between the changes of these values and the content of TPI. A possible explanation was given by the investigation of the miscibility and surface morphology of the blends.关键词
