                 单的工艺合成了一种氟硅缩水甘油醚环氧单体(FSi-GE),采用核磁共振波谱仪(NMR)和傅立叶变换
                 红外光谱仪(FT-IR)对该单体的结构进行了表征,并研究了其对环氧单体 3,4-环氧环己基甲基 3,4-
                 环氧环己基甲酸酯(E4221)和 1,2-环氧−4-乙烯基环己烷(VOH)组成的阳离子光聚合体系的光聚合
                 动力学、表面疏水性、耐热性及拉伸性能的影响。结果表明:当 FSi-GE 的添加量从 0增加到 0. 5%,体
                 系的环氧基团最终转化率从 60. 6% 上升到 65. 7%,固化膜表面水接触角从 56. 9°升至 104. 6°,断裂伸
                 长率从22. 96%升至41. 22%,同时耐热性提高。但随着FSi-GE的含量继续增加,表面水接触角、耐热
                 性和断裂伸长率都呈现略微下降的趋势。说明加入适量的 FSi-GE 能够有效提高 E4221/VOH 体系的                                               探

                      Abstract:Developing cationic photopolymerizable fluorosilicone monomers is one of the
                 important  research  directions  in  the  field  of  photopolymerization. A  fluorosilicone  glycidyl

                 ether epoxy monomer(FSi-GE)was synthesized by using readily available raw materials and
                 simple  synthesis  process,and  the  monomer  structure  was  characterized  using  NMR  and
                 FT-IR. The  influence  of  FSi-GE  on  polymerization  kinetics,surface  water  resistance,heat
                 resistance  and  tensile  properties  of  the  cationic  photopolymerization  system  comprised  of
                 3,4-epoxy-cyclohexyl  methyl  3,4-epoxy-cyclohexyl  formate(E4221)and  1,2-epoxy-4-

                 vinylcyclohexane(VOH)was investigated. The results showed that when FSi-GE amount was

                                           t
                 increased from 0 to 0. 5%,he final conversion of epoxy group of the system was increased from
                                                                                                        t

                 60. 6% to 65. 7%,he surface water contact angle was increased from  56. 9° to 104. 6°,he
                 elongation at break was increased from 22. 96% to 41. 22%,and the heat resistance was also
                 improved. However,with  the  further  increase  of  FSi-GE  amount,he  surface  water  contact
