Abstract

A two-step process was used to prepare PP/MAPP/C15A/MWNT ternary nanocomposites system. The effect of the addition of MWNT on the delamination of clay layers in the polymer matrix has been studied through XRD. The similar crystallinity level was noticed after the addition of clay and MWNT together in the PP matrix through XRD. Higher mechanical properties of the ternary nanocomposites system were noticed than neat PP and its binary nanocomposites systems. Differential scanning calorimeter (DSC) technique was utilized to investigate the effect of both nanofillers on crystallization temperature (). And a shift in towards higher temperature was noticed in all the nanocomposites. Thermogravimetric analysis revealed an improved thermal stability of the ternary nanocomposites system. The dynamic mechanical response of PP and its binary and ternary nanocomposite systems was evaluated. The dispersion of the nanoparticles was investigated employing transmission electron microscopy (TEM). The combined effect of clay and MWNT on the properties of PP was investigated and summarized.

纳米硅酸盐与MWNT杂化对聚丙烯力学、热及动态力学性能的影响

采用两步法制备了PP/MAPP/C15A/MWNT三元复合材料体系。采用XRD研究了MWNT的加入对聚合物基体中粘土层脱层的影响。通过XRD分析发现，在PP基体中同时加入粘土和MWNT后，结晶度相近。三元复合材料的力学性能明显高于纯PP及其二元复合材料体系。利用差示扫描量热仪(DSC)技术研究了两种纳米填料对结晶温度的影响。并且在所有的纳米复合材料中都发现了向更高温度的转变。热重分析表明，三元复合材料的热稳定性得到了改善。对聚丙烯及其二元和三元纳米复合材料的动态力学响应进行了评价。利用透射电子显微镜(TEM)研究了纳米颗粒的分散。研究并总结了粘土和MWNT对PP性能的共同影响。

期刊介绍： Chinese Journal of Engineering Design is a reputable journal published by Zhejiang University Press Co., Ltd. It was founded in December, 1994 as the first internationally cooperative journal in the area of engineering design research. Administrated by the Ministry of Education of China, it is sponsored by both Zhejiang University and Chinese Society of Mechanical Engineering. Zhejiang University Press Co., Ltd. is fully responsible for its bimonthly domestic and oversea publication. Its page is in A4 size. This journal is devoted to reporting most up-to-date achievements of engineering design researches and therefore, to promote the communications of academic researches and their applications to industry. Achievments of great creativity and practicablity are extraordinarily desirable. Aiming at supplying designers, developers and researchers of diversified technical artifacts with valuable references, its content covers all aspects of design theory and methodology, as well as its enabling environment, for instance, creative design, concurrent design, conceptual design, intelligent design, web-based design, reverse engineering design, industrial design, design optimization, tribology, design by biological analogy, virtual reality in design, structural analysis and design, design knowledge representation, design knowledge management, design decision-making systems, etc.
