中文摘要： 聚离子液体是一种特殊的聚电解质材料，在高分子催化剂、离子导电材料及气相分离材料等领域具有重要应用价值，已成为目前高分子材料学科的研究重点。空心微球材料由于其独特的内部空腔结构，具有密度小、比表面积大、壳层渗透性好等诸多优良性能，已被广泛用于包封、催化及药物载体等领域。因此，兼具以上两种材料优良性能的聚离子液体空心微球材料应该具有非常重要的研究价值。本项目即定位于这一交叉研究领域，拟开展聚离子液体中空微球制备、功能化及应用研究。通过设计各类可聚合离子液体单体，采用乳液聚合方法，结合聚合诱导相分离和界面聚合原理，开发制备聚离子液体中空微球的无模板、简单一步、大规模合成新方法。在此基础之上，将通过乳液共聚方法，制备系列离子液体共聚以及具有交联壳层结构的中空微球材料。还将开展该类新型中空微球材料的应用研究，包括利用其内部空腔封装纳米粒子和以其为新型催化剂实现对化学反应的催化等。

英文摘要： Poly(ionic liquid) , one special polyelectrolyte, has become research priorities in the field of polymer material because of their potential application value in the area of macromolecule catalyst, ion-conductive material, gas-phase separation material, etc. Hollow spheres have spurred great interest in encapsulation, catalysis and drug carrier due to their unique characteristics of special greater internal cavities, low density, big specific surface area, and good permeability. Consequently, by combination of the excellent performance of poly(ionic liquid) and hollow spheres, poly(ionic liquid) hollow spheres will have very vital research values. This proposal is locating in this special crossed research field and focusing on preparation, functionalization and corresponding application of poly(ionic liquid) hollow spheres. Diverse polymerizable ionic liquid will be designed and synthesized firstly. Poly(ionic liquid) hollow spheres will be prepared in one step without any template by combination of emulsion polymerization, interfacial polymerization and phase separation. Furthermore, a series of cross-linked poly(ionic liquid) hollow spheres and poly(ionic liquid-comonomer) hollow spheres can be prepared by virtue of emulsion co-polymerization. Finally, the corresponding applications of poly(ionic liquid) hollow spheres will be explored preliminarily, e.g. encapsulating of nanoparticles in the cavity of poly(ionic liquid) and testing the catalysis functionality of poly(ionic liquid).
