| 摘 要： | 以甲苯二异氰酸酯(TDI)和甲基丙烯酸羟乙酯(HEMA)为原料,合成了丙烯酸酯/聚氨酯(PUA)预聚体;采用细乳液聚合法,合成了聚含氟PUA细乳液。使用红外光谱(FT-IR)和核磁共振(1H-NMR)表征了PUA预聚体及共聚物的结构组成,用激光光散射粒度仪(PCS)分析了乳胶粒的粒径及其分布,并考察了氟单体用量对乳胶膜的吸水率和表面性能的影响。研究结果表明,乳胶粒的粒径随着PUA预聚体用量的增加而增大;当氟单体质量分数由0增至20%时,乳胶膜的吸水率由10.3%降至4.2%,表面自由能由34.89mJ/m2降至15.66mJ/m2,说明氟单体的加入较好地改善了乳胶膜的表面性能。

| Abstract: | The acrylate/polyurethane (PUA) prepolymer was synthesized with TDI and HEMA as raw lymerization. The composition and structure of the PUA prepolymer and copolymer ware characterized by FT-IR and 1H-NMR,the particles size and size distribution of the miniemulsion were characterized by 1 PCS,the effect of fluorine-monomer content were investigated on water absorption and surface property of the copolymer films. The research results showed that the particles size of miniemulsion was increased with the increas... |
