摘要: 采用不同硅烷偶联剂对纳米凹凸棒土(简称纳米凹土)进行了改性,通过熔融共混法制备了聚对苯二甲酸乙二醇酯(PET)/纳米凹土复合材料,用毛细管流变仪和旋转式流变仪及扫描电子显微镜研究了PET/纳米凹土复合材料的流变特性、动态黏弹性以、动态力学性能及复合材料的微观形态。结果表明,纳米凹土的加入降低了PET的熔体黏度和玻璃化转变温度;使复合材料呈现假塑性流体特征;纳米凹土颗粒间不存在相互作用;硅烷偶联剂使纳米凹土能降低熔体的表观黏度,在PET中分散得较好。

Abstract: Silane modified nano-attapulgite was melt blended with poly(ethylene terphtalate) (PET) forming composites, whose rheological, dynamic mechanical properties, and microstructure were investigated. It showed that the nano-attapulgite was finely dispersed in the PET matrix and reduced the viscosity and glass transition temperature of PET.

Key words: poly(ethylene terphthalate), nano-attapulgite, rheological behavior, composite
