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. 英文主題詞UV-curable; polyurethane; aqueous dispersions coatings; thiol-ene chemistry; preparation 結(jié)題摘要 本項(xiàng)目將硫醇-烯化學(xué)方法和水性聚氨酯分散體合成技術(shù)相結(jié)合，建立了一套制備可紫外光固化聚氨酯水性涂料的新體系，證明了基于硫醇-烯化學(xué)的新型可紫外光固化的“相分離反應(yīng)型”聚氨酯水性涂料的可行性，闡明了該新型紫外光固化聚氨酯水性涂料的不同制備方法和工藝條件對(duì)其室溫儲(chǔ)存穩(wěn)定性能和光固化行為的影響，發(fā)現(xiàn)了體系中不同分子結(jié)構(gòu)、硫醇和烯類單體數(shù)量是影響其穩(wěn)定性和光化學(xué)性能的關(guān)鍵因素；實(shí)時(shí)紅外和photo-DSC等方法測(cè)試證明該新型水性聚氨酯分散體涂料具有良好的室溫貯存穩(wěn)定性、光固化性能和薄膜力學(xué)性能；在此基礎(chǔ)上，通過POSS、中空二氧化硅微球、碳納米管和水性聚氨酯的納米功能復(fù)合，構(gòu)建了具有良好相容性和協(xié)同增強(qiáng)效應(yīng)的新型有機(jī)/無機(jī)納米摻雜改性聚氨酯水性涂料；進(jìn)一步對(duì)其微觀結(jié)構(gòu)、熱、光和力學(xué)等性質(zhì)進(jìn)行深入研究，為構(gòu)造高性能和功能性水性聚氨分散體新材料提供理論和實(shí)驗(yàn)依據(jù)。在Polymer、Chem Phys Lett、Appl Phys Lett、Appl Surf Sci和J Appl Polym Sci等刊物發(fā)表論文31篇（SCI收錄19篇），授權(quán)發(fā)明專利7項(xiàng)，申請(qǐng)11項(xiàng)發(fā)明專利。 |
