紫外光固化阳离子聚合复合胶粘剂折射率光透过率 UV-curable cationic polymerization composite adhesive refractive index transmittance

摘要

以三芳基六氟磷酸硫鎓盐为引发剂, 钛酸四异丙酯(TIP)为无机前驱体, 3,4-环氧环己基甲基-3,4-环氧环己基甲酸酯为单体, 制备了含TiO2纳米结构的紫外光固化阳离子复合胶粘剂。通过原子力显微镜对复合胶粘剂形貌进行表征, 研究了TIP含量对胶粘剂折射率和光透过率的影响。结果表明：TiO2无机相均匀地分散在胶粘剂的聚合物基体中, 平均粒径约为20 nm；随着体系中TIP质量分数的变化, 复合胶粘剂折射率为1.510 3~1.540 9可调；胶粘剂的光透过率随TIP质量分数增加略有减低, 但当TIP含量高达40%时, 光透过率维持在90%左右。

Abstract

UV-curable cationic composite adhesives containing TiO2 nanostructures were prepared by using 3,4-epoxycyclohexylmethyl-3, 4-epoxycyclohexanecarboxylate(CE) as monomer, triphenylsulfonium hexafluorophosphate salt (PI-432) as photoinitiator and titanium isopropoxide(TIP) as inorganic precursor. The morphology of the composite adhesives was characterized by atom force microscopy(AFM). The effect of TIP content on refractive index and transmittance of adhesives were studied. The results show that TiO2 nanostructures, the average diameter of which is 20 nm or so, can be uniformly dispersed in polymers of composite adhesives. The refractive index of adhesives can be adjusted from 1.501 9 to 1.544 9 with the change of TIP content. The transmittance of adhesives has a slight reduce with the increase of TIP content. When TIP content is up to 40%, the transmittance of composite adhesives remains around 90% or so．
