巨型表面活性剂的出现为构建热力学稳定和亚稳定的超分子纳米结构提供了新的机会。本项目拟通过设计一类新型的巨型表面活性剂聚合物杂化材料，来实现在多重尺度上（特别是在数十个纳米的尺寸）对这类软物质的超结构的更好调控。本项目将利用可控的高分子化学方法（如开环移位聚合）， “点击”化学和其他精确的有机化学手段来设计合成基于亲水多面体低聚倍半硅氧烷-聚苯乙烯连接物为大分子单体的目标聚合物。在溶液，本体和薄膜三种相态下研究目标产物的多尺度自组装行为，分析其超分子结构和相行为。我们将通过对比巨型表面活性剂聚合物与其他种类两亲分子（如小分子表面活性剂与两亲性嵌段聚合物）在物理性质上的异同来探索此类大分子组装行为的普遍规律，了解其结构与性能之间的内在联系，进一步拓展巨型表面活性剂的分子库，并为巨型分子在高分子材料工程上的应用提供一些新的思路。

The emergence of giant surfactant offers new opportunities in the construction of various thermodynamic stable and metastable supramolecular nanostructures. This proposal strives to design a new class of poly (giant surfactant)-based hybrid materials to precisely control and rigorously tune their super-structures at multiple length scale (particularly at tens of nanometers) in a better way. Controlled polymerization methods like ring-opening metathesis polymerization (ROMP), “click” chemistry and other kinds of precise organic transformation will be fully employed to design and synthesize the desirable poly (hydrophilic polyhedral oligomeric silsesquioxane (POSS)-polystyrene conjugates). The self-assembly behaviors of resulting macromolecules will be performed in solution, bulk, and thin film state to investigate their supramolecular structure formation and phase behaviors. We will compare poly (giant surfactant) with other kinds of amphiphiles like small molecular surfactants and amphiphilic block copolymers in their intrinsic physical properties to understand the general principle of their hierarchical assembly behaviors. This study will broaden the scope of synthetically available giant surfactants for further systematic investigations on their structure-property relationships, enabling the general implications for giant molecule-based polymer materials and engineering.
