中文摘要： 经济、高效地解决含油/有机污染物废水污染问题对于环境保护、石油和化学工业清洁生产具有重要意义。针对传统吸附材料在含油/有机污染物废水处理方面存在的不足（如吸附选择性差、吸附容量低等），项目拟通过合成新型单体及选择聚合体系溶剂，调控微孔共轭聚合物的结构和形貌，探索制备对水体中油、有机污染物具有高吸附选择性、高吸附容量的新型超疏水/亲油微孔共轭聚合物，并考察其在模拟及实际含油/有机污染物废水中的分离和选择性吸附性能。研究微孔共轭聚合物的孔性能、形貌等物化性能对其表面水/油浸润性能、吸附容量以及选择性吸附性能影响。借助先进分析测试手段和计算模拟，在分子水平上揭示微孔共轭聚合物的结构与其吸附性能之间的构效关系。项目的实施不但可能得到在含油/有机污染物废水处理方面具有应用价值的高性能吸附材料，而且可为进一步设计、制备高吸附容量、高吸附选择性的新型超疏水/亲油微孔共轭聚合物提供基础实验数据和科学依据。

英文摘要： The development of efficient and economic strategy to address pollution issues arising from oil spills or organic wastewater should be of great importance for environmental protection and clean production of petrochemical industry. The traditional absorbent materials, however, have their respective drawbacks such as poor selectivity, low adsorption performance, etc. Accordingly, we proposed here for preparation of a series of novel, superhydrophobic and superoleophilic conjugated microporous polymers (CMPs) with high selectivity and adsorption performance for removal and selected adsorption of oils or organic contaminates from wastewater. The structure and morphology of the CMPs can be tuned by using various as-synthesized monomers or various solvents during polymerization procedure, respectively. The separation and selected adsorption performance of the CMPs for treatment of simulated wastewater and actual wastewater will be evaluated. The effect of porosity properties and morphology of the CMPs on their surface wettability, adsorption performance and selected adsorption performance will be investigated. By combination with advanced analysis/measurement and computational simulation, the relationship between the adsorption performance and the structure of the as-synthesized CMPs will be studied at the molecular
