采用N-(三甲氧基硅丙基)-4-叠氮-2,3,5,6-四氟苯甲酰胺(PFPA-silane)改性纳米氧化锌,并将PFPA-silane接枝在有机硅聚合物链上.接枝反应改变了纳米复合物的折光指数,并使ZnO纳米粒子与有机硅基体的折光指数更加匹配.这减少了纳米氧化锌粒子对光的散射作用,增加了纳米ZnO-有机硅纳米复合物的透明性.所制备的复合物通过接枝改性后透光率最多可提高50%.研究结果表明无机物和聚合物的折光指数的匹配程度可以通过偶联剂与聚合物基体的反应来进行调控.
Nano zinc oxide was modified with N- (trimethoxysilylpropyl) -4-azido-2,3,5,6-tetrafluorobenzamide (PFPA-silane) and grafted on PFPA-silane in organic Silicon polymer chains.The grafting reaction changes the refractive index of the nanocomposites and matches the refractive index of the ZnO nanoparticles with that of the organosilicon matrix.This reduces the scattering of light by the ZnO nanoparticles and increases the nano ZnO - The transparency of the organosilicon nanocomposites The prepared composite can be modified by grafting up to a maximum of 50% transmittance The results show that the degree of matching of the refractive indices of the inorganic and the polymer can be improved by the coupling agent and Polymer matrix reaction to regulate.
