A novel UV-curable polyurethane coatings system was well established. The results proved the feasibility of the UV-curable polyurethane coatings can be prepared by blending multifunctional thiol- and ene-terminated polyurethane aqueous dispersions. Our reports illustrated the impact of the different preparation methods and technology conditions on solution stability and photopolymerization behavior of the resulting polyurethane coatings. The key factors affecting their performance of their solution stability and photopolymerization behavior were the composition, structure, thiol and ene numbers of resulting polyurethane dispersions. It was found that the resulting polyurethane coatings showed good solution stability, high photopolymerization activity and excellent physical properties by FT-IR, photo-DSC and DMA measurements. On this basis of it, new organic-inorganic nano-composite systems were well constructed by chemically doped by polyhedral oligomeric silsesquioxane (POSS), hollow SiO2 microspheres and carbon nanotubes (CNTs) with polyurethane aqueous dispersions. The results showed that the POSS, hollow SiO2 microspheres and CNTs have good compatibility and synergistic enhancement performance with polyurethane dispersions. Through the in-depth study of their microstructure, thermal, optical and mechanical properties, theoretical and experimental basis for the development of high-performance and functional polyurethane aqueous dispersions coatings were developed. 31 papers were published in journals of Polymer, Chem. Phys. Lett., Appl. Phys. Lett., Appl. Surf. Sci. and J. Appl. Polym. Sci. etc and 7 authorized and 11 pendent patents. 英文主题词UV-curable; polyurethane; aqueous dispersions coatings; thiol-ene chemistry; preparation 结题摘要 本项目将硫醇-烯化学方法和水性聚氨酯分散体合成技术相结合，建立了一套制备可紫外光固化聚氨酯水性涂料的新体系，证明了基于硫醇-烯化学的新型可紫外光固化的“相分离反应型”聚氨酯水性涂料的可行性，阐明了该新型紫外光固化聚氨酯水性涂料的不同制备方法和工艺条件对其室温储存稳定性能和光固化行为的影响，发现了体系中不同分子结构、硫醇和烯类单体数量是影响其稳定性和光化学性能的关键因素；实时红外和photo-DSC等方法测试证明该新型水性聚氨酯分散体涂料具有良好的室温贮存稳定性、光固化性能和薄膜力学性能；在此基础上，通过POSS、中空二氧化硅微球、碳纳米管和水性聚氨酯的纳米功能复合，构建了具有良好相容性和协同增强效应的新型有机/无机纳米掺杂改性聚氨酯水性涂料；进一步对其微观结构、热、光和力学等性质进行深入研究，为构造高性能和功能性水性聚氨分散体新材料提供理论和实验依据。在Polymer、Chem Phys Lett、Appl Phys Lett、Appl Surf Sci和J Appl Polym Sci等刊物发表论文31篇（SCI收录19篇），授权发明专利7项，申请11项发明专利。 |
