摘　　要： 研究利用聚烯丙基胺盐酸盐与SiO2纳米粒子在有机玻璃片表面的静电自组装来进行超亲水防雾改性。水接触角分析显示随着双电层数目的增加,有机玻璃的亲水性明显改善,并在20双电层时呈现超亲水性。原子力显微镜观察表明,有机玻璃片的超亲水性与其表面形成规整排列的纳米微孔结构,有利于水汽在有机玻璃片表面形成水膜有关。防雾测试结果进一步表明,表面自组装改性能明显改善有机玻璃片的防雾性能。此外,透光率分析结果还得出有机玻璃片改性后并不影响其透光性,反而还会因为反射光强减弱而略微提高。 A superhydrophilicity antifogging modification of poly（methyl methacrylate）（PMMA）plate was studied by static electronic self-assembly of poly（acryllamine hycrochloride）and SiO2 nano-particles on PMMA plate surface.The water contact angle analysis showed that the hydrophilicity of PMMA plate was greatly improved with increasing the number of electric bilayers,and a super hydrophilic surface was achieved while coating 20 bilayers.The atomic force microscope observation showed that the super hydrophilic surface maybe resulted from the regular arrangement nanoporous structure which was in favor of the formation of water layer.A good antifogging performance was further obtained in PMMA plate with 20 coating bilayers via an antifogging test.In addition,the visible light transmission of self-assembly coating modified PMMA plates was not decreased but increased a little bit because of the reflection reduction on the surface.
