摘要
Abstract
Polyamide 10T(PA10T)/MoS2 composites were prepared by incorporating MoS2 into semi-aromatic polyam-ide PA10T through melt blending.Differential scanning calorimetry(DSC)was conducted to study the non-isothermal crystallization behavior of PA10T and its composites at different cooling rates.The effect of particle size of MoS2 on the crystallization behavior of PA10T was investigated.The non-isothermal crystallization kinetics of PA10T and its com-posites was studied by using the Jeziorny's and Mo's methods,and their non-isothermal crystallization activation energy was calculated by using Kissinger's method.The results indicated that the crystallization rate of PA10T was fastened and its crystallization time was shortened.After being filled with MoS2,the PA10T composites demonstrated a larger crystallization temperature range,an extended half-crystallization time,a slowed crystallization rate,and a lower poten-tial barrier required for nanoscale MoS2 to overcome in the crystallization process of PA10T.The analysis results ob-tained from the Jeziorny's and Mo's methods indicated that the MoS2 with different particle sizes had no significant effect on the non-isothermal crystallization rate of PA10T.In a certain range of cooling rates,incorporating nanometer or mi-cron MoS2 into PA10T can be adopted as an effective means to control the crystallization rate of PA10T in its processing.关键词
