硅基环氧化聚合物组装Janus粒子增强涂层表面双疏与界面作用的研究

Silicone-based epoxide polymers (SEPs) effectively combine the advantages of -Si-O- group-containing compounds and epoxide polymers to provide the possibility of building the hydrophobic/hydrophobic surface and enhancing interface interaction. Block-structured SEPs hybrid copolymer could self-assembly into asymmetric two-sided particles, named as Janus particles, which could migrate directionally into film surface to control the surface wettability and to realize the regulation of interface enhancement. Therefore, SEPs will become the focus of high performance film materials in the future. However, the key point is to assembly Janus particle for building micro/nanostructured surface in order to coherence between the surface wettability and interface interaction, but few of researches are reported so far. Therefore, this project aims to design and synthesize block-structured SEPs, to regulate the morphology and distribution of Janus particles self-assembled by SEPs in solution, to reveal the interaction of Janus particle-particle and particle-interface during the film forming, to research the ordered surface and wettability regulation controlled by Janus particles, and their durability. Through these researches, the relationship between the well-defined surface, the wettability and enhancing interface interaction of film is explored, and the regulation mechanism of topology structures with the well-defined surface and wettability is established. It is hoped that the results of this research could provide the scientific basis and technical support to the high-performance SEPs hybrid copolymer.

硅基环氧化聚合物(SEPs)有效地结合了含有-Si-O-基团的硅基化合物与环氧化聚合物的优势，为获得疏水/疏油表面的同时增强界面粘接性能提供了途径。通过嵌段型SEPs杂化聚合物溶液组装形成结构不对称的双面粒子(Janus粒子)，再利用Janus粒子的特性实现表面双疏性能和界面粘接作用的调控，必将会成为杂化聚合物的关注焦点。然而，如何利用Janus粒子调控表面和界面性能是SEPs杂化聚合物研究的关键所在，至今鲜有报道。鉴于此，本项目设计并合成结构可控的嵌段型SEPs杂化聚合物、研究SEPs溶液组装调控Janus粒子形貌和粒径分布、探明Janus粒子-粒子和粒子-界面的相互作用与迁移行为及定向排列和成膜机理、研究Janus粒子构建微/纳有序结构表面提高双疏性能与耐久性能、揭示表面粗糙度与增强表面双疏性能和界面粘接性能的关系等，为SEPs杂化聚合物相关科学问题的研究提供科学依据和技术支持。
