中文摘要：
从注射制品形态控制和结构表征的角度探讨高分子材料加工-形态-性能之间的关系。研究中采用动态保压和传统注射成型方法来制备注射样品，在注射成型过程中引入剪切应力场的作用，制得的样品表现出明显的多层次结构，从外向里分别为皮层、剪切层、芯层，表现出不同的相形态、结晶形貌以及取向行为。研究发现，剪切应力对聚烯烃的形态发展和结构变化具有重要影响。在剪切应力的作用下，聚烯烃共混物中分散相会发生变形、取向，从而导致共混物的相转变点发生移动；结晶形态从球晶转变为shish-kebab结构；聚烯烃共混物在高剪切应力下相容，低剪切下发生相分离；HDPE/iPP共混物的注射制品中出现附生结晶，在HDPE/炭纳米管体系获得杂化串晶，iPP/晶须体系获得糖葫芦晶体等有趣现象。发表SCI论文80篇，出版专著一部，获国家与省部级奖励多项。希望这些成果有助于丰富注射成型高分子加工理论和实践，为通过成型加工制备低成本、高性能通用高分子材料提供理论指导。
