1. 高分子结构与热塑性材料设计

基于高分子学科的热塑性材料(Thermoplastic Materials) (如塑料)产业是现代国民经济中关键的支柱工业项目,在现代社会生产和生活中具有重要的地位。在热塑性材料之中,热塑性弹性体既有橡胶的高弹性,也具有塑料的热塑性,目前已大规模应用于生活日用品和工程制品中,例如包装,医疗元件和工程部件等。研究新型高端热塑性材料对我国经济发展以及制造业升级具有举足轻重的作用。目前,基于嵌段高分子(Block Copolymer) 的热塑性产品已经占据了大部分热塑性材料的市场。本课题组将研究基于嵌段高分子的热塑性材料,探讨嵌段高分子结构与行为对热塑性材料的力学性能、流变行为以及相变特点的影响,从理论上设计新型的热塑性材料。本课题将涉及高分子化学,高分子物理以及高分子加工方面知识,联系理论与实际;致力于揭示高分子结构与性能方面的理论关系,从而能够指导开发新一代热塑性材料或产品。

2. 杂化高分子及其材料设计

在近几十年来的高分子领域中,杂化高分子材料引起了广泛的关注。杂化高分子材料是一种非常新颖且有独特性能的功能高分子材料。杂化高分子一般具有高分子的链结构,并在主链或者支链上有一定数量的杂化元素。杂化高分子既含有高分子材料的力学性能和可加工性能,还具有杂化有机小分子的功能特点,如催化,光学和电化学性能等等。考虑到杂化有机小分子相对于常见的有机分子的与众不同的特点,研究杂化高分子可以极大的拓展当前高分子材料的功能、种类和应用。本课题将着力于设计新型的杂化高分子,并开发和研究基于杂化高分子的功能性材料, 例如具有光学功能的高分子薄膜等等。课题涉及高分子合成以及初步的高分子物理知识,将研究杂化高分子的组成、结构、性能之间的联系和关系,为设计新材料提供理论基础。


1. Thermoplastic Materials
With tremendous applications in our daily lives and industry, thermoplastic materials are critically important in the world. One important subclass of thermoplastic materials is thermoplastic elastomers (TPEs), which combines the advantages of thermal processability and elasticity. TPEs are broadly applied in the daily and industrial products, such as packaging, medical device and engineering component. Nowadays, thermoplastic materials based on block copolymers play important role in the market of thermoplastics. In our group, we will investigate thermoplastics from block copolymers, including their mechanical, rheological and phase behaviors, to design new types of thermoplastics.
2. Hybrid Polymers
In the past decades of polymer science, hybrid polymers have received lots of attention. Hybrid polymers are new and functional polymeric materials, which have normal polymeric architectures with hybrid elements in side-chain or backbone of polymers. Hybrid polymers not only have the processability of normal polymers, but also retain the functionalities of hybrid elements. Considering such advantages, our group will explore new hybrid polymers, including their new properties, functionalities and applications.
