摘要
目的制备低折射率光固化涂层。方法以全氟十一烷基丙烯酸酯(FA)、甲基丙烯酸三氟乙酯(TRIFEMA)、四氢呋喃丙烯酸酯GM61P00(THFA)和聚氨酯丙烯酸酯(PU)为主要组分,考察各组分用量对涂层接触角、吸光度和折射率的影响。结果在一定的用量范围内,折射率随FA和TRIFEMA用量增加而降低,随THFA和PU用量增加而升高;接触角随FA和TRIFEMA用量增加,先增大,然后保持稳定,随THFA和PU用量增加而减小;吸光度随FA用量增加而增大,随TRIFEMA,THFA和PU用量增加而减小。结论低折射率光固化涂料的最佳配比为m(FA)∶m(TRIFEMA)∶m(THFA)∶m(PU)=2∶5∶1.25∶1,其涂层折射率为1.387,吸光度为0.0091。
Objective The aim of this paper was to prepare the low-refractive index UV-curable coating. Methods 1 H, 1 H, 11 H-perfluoroundecyl acrylate ( FA ), Trifluoroethyl methacrylate ( TRIFEMA ), Tetrahydrofurfuryl acrylate GM61P00 (THFA) and Polyurethane acrylate(PU) were used as the main ingredients, and their influences on the wa- ter contact angle, the absorbance of the film and the refractive index of the coating were investigated. Results Within a certain dosage range, the refractive index decreased with the increasing content of FA or TRIFEMA, and increased with the increase of THFA or PU ; the contact angle increased and then remained stable with the increase of the FA and TRIFEMA, while it decreased when THFA and PU increased; the absorbance increased with increasing FA content, but when TRIFEMA, THFA and PU increased, the absorbance became lower. Conclusion The optimal proportion for the low-refractive index UV-curable coating was m(FA) : rn(TRIFEMA) : m(THFA) : rn(PU)= 2 : 5 : 1.25 : 1. Under this condition, the refractive index was 1. 387, and the absorbance was 0. 0091.
