纳米材料在杂化聚氨酯中的效应

摘要

近年UV固化水性聚氨酯（WPU）或聚氨酯丙烯酸酯（WPUA）纳米复合材料的特性受到众多研究者的关注，并进行了多项研究。采用的纳米材料包括SiO2、Al2O3、TiO2、ZnO、POSS、碳纳米管、碳纳米纤维等。重点综述了WPU和WPUA低聚物（预聚物）的制备、纳米材料的改性处理、WPU/纳米颗粒和WPUA/纳米颗粒杂化复合材料的制备以及所得制品的表征、性能等。%Recently,the chracteristics of UV-curable waterborne polyurethane (WPU) and waterborne polyurethane-acrylate (WPUA) nanocomposites have been attracted attention of some researchers,and many studies about them were carried out.The nano-materials used for these studies include SiO2,Al2O3,TiO2,ZnO,POSS,carbon nanotubes,carbon nanofibres,etc.The preparation of WPU and WPUA oligmers (prepolymers),the modifying of nano-materials,the preparation of WPU and WPUA/nano particle hybrid composites as well as the characterization and properties of formed products are reviewed emphatically.
