The results of the uni - factor experiments and perpendicular experiments show their best mechanic synthesizing craft as followed : nvp ( 10 % wt ), kh570 ( 20 % wt ), hema ( 70 % wt ), initiator ( 0. 2 % wt ), crosslinker ( 20 % wt ), reacting 20 hours under 80 c. the factors which influenced organic silicon modified pvp hydrogel soft contact lens material ' s swelling capabilities were researched, which included temperature, monomer content, ion concentration etc. the experiments showed the equation swelling content ewc improved with the increase of nw, droped with the increase of kh570 and ion concentration, improved then droped with the raise of temperature, and hydrogels got the least ewc at 45 c. experiment carried on todiscuss water dehydration mechanism of organic silicon modified pvp hydrogel soft contact lens materials, which showed dehydration process could be divided into evaporating stage and diffusing stage
正交實驗結果表明, nvp ? hema ? kh570共聚物的機械性能最佳時,其合成工藝條件為: nvp用量10 (質量百分含量,下同) , kh570用量20 , hema用量70 ,引發劑aibn用量0 . 2 ,交聯劑nmba用量0 . 2 ,反應溫度為80 ,反應時間16h 。討論了單體配比、溶脹溫度、離子濃度等因素對有機硅改性pvp水凝膠軟接觸透鏡材料溶脹性能的影響。實驗得出:水凝膠材料的平衡溶脹度ewc隨單體nvp含量的增加而增大, ewc隨kh570用量的增加而減小,隨離子濃度的增大而略微降低,隨溶脹溫度的升高先稍微下降後有所提高, 45時平衡含水量最低。The oxygen sensing properties of the membranes have been studied, the results indicate that the membranes with ru ( phen ) 3cl2 have better oxygen - sensitivity than those with ru ( bpy ) 3cl2, and the membranes with the formamide content of 16 % ( v / v ) and ru ( phen ) 3cl2 content of 2. 10g / l in the precursor mixture have the best structure and quality. the fiber optic gas oxygen sensor with this sensing membrane has a detection limit of 5ppm, a response time of less than 30s, excellent reproducibility and stability. ( 2 ) a new kind of organically modified oxygen - sensitive membrane based on fluorescence quenching was prepared by sol - gel method, using dds and teos as the mixed precursor, rufchenbcla as the indicator
實驗證明:該類敏感膜的tan _ 0 tan值與氧氣濃度存在良好的線性關系;包埋ru ( phen ) _ 3cl _ 2的凝膠膜的氧敏感性相對較好;當甲酰胺為16體積比含量, ru ( phen ) _ 3cl _ 2在前驅體中濃度為2 . 10g l時,制備的敏感膜結構和性能最佳;對氣態氧檢測時,該敏感膜的響應時間小於30秒,檢測下限為5ppm ,具有較好的重復性和穩定性。
