以反式聚异戊二烯(TPI)为基体,通过加入有机黏土(OC)制备了TPI/OC纳米复合材料(TPICNs)。通过X射线衍射、差示扫描量热、动态力学分析和扫描电子显微镜等手段分别考察了TPICNs的结晶情况、形状记忆性能、力学性能和微观形貌。结果表明,随着OC用量的增加,TPICNs的结晶度、拉伸强度和形状回复率均先增大后减小;当OC用量为1.2份(质量)时,TPICNs的拉伸强度最大且展现出最好的形状记忆行为;TPICNs断面处结晶颗粒分布均匀。
- Abstract:
-
trans-polyisoprene(TPI)/organic clay (OC) nanocomposites (TPICNs) were prepared by adding OC into TPI matrix. The crystallisation, shape memory properties, mechanical properties and micromorphology of TPICNs were investigated by X-ray diffraction, differential scanning calorimetry, dyna-mic mechanical analysis and scanning electron microscopy, respectively. The results showed that the crystallinity, tensile strength and shape recovery rate of TPICNs increased first and then decreased with increase of OC content. When the amount of OC was 1.2 phr (mass), the tensile strength of TPICNs was the highest and the shape memory behaviour was the best. The crystalline particles on the fraction surface of TPICNs were uniformly distributed.
