中文摘要： 高分子链结构定制及自组装分别是高分子化学及物理的热点与前沿科学问题。基于人类需求（衍生的材料功能/化工产品工程）而言，上述两个问题高度统一。本项目从化工产品工程角度开展上述问题的统一性研究。 首先，基于仿生学，以自然界的荷叶自清洁进行材料仿生设计，构建具有自清洁的"亚"两亲性"氟硅"嵌段聚合物树脂；其次，耦合"活性"/可控聚合过程的全程动力学与反应器模型建立上述聚合物链结构的定制技术，实现以功能为导向的聚合物链结构定制；另外，采用多尺度贯通模拟方法建立树脂凝聚态的粗粒化模型并对其自组装行为模拟以确定其聚集态，结合聚合与自组装实验共同确定聚集态与链结构关系，实现利用自组装调控聚合物聚集态；最终，构建以产品功能为导向的聚合物结构与形貌同时定向制备技术。 本项目系统研究一个全新多尺度体系，将对定制与开发新化工材料产生积极作用，并促进学科交叉，丰富高分子学科内涵及拓宽化学工程学科外延。

英文摘要： Recent studies have demonstrated that tailor-made chain structure and self-assembly are hot topics and frontier issues in polymer chemistry and physics fields, respectively. The two issues are connected and consistent in terms of human needs, that is, material function and chemical product engineering. In this project, we will focus on studying the relation of the two issues above. First, based on the simulation of lotus leaf, we will design sub-amphiphilic fluorosilicone block copolymers with self cleaning function in this project. Next, we will develop the preparation technique of these copolymers by coupling "living"/controlled polymerization kinetics and reactor model to implement preparing polymers with tailor-made chain structure of human needs oriented material function. In addition, we will establish coarse grained models for resins at condensed state using a multi scale through simulation method to describe the self-assembly of polymers. By combining these coarse grained models with polymerization and self-assembly experiments, we will obtain the relation between the chain structure and the aggregation state of copolymers to implement controlling the aggregation state by self-assembly. Finally, following the chemical product engineering, the technique for synthesis of block copolymers with simultaneous
