| 中文摘要 | 用铬酸氧化法在聚乙烯薄膜的表面引入了羧基阴离子,合成了端基阳离子性的聚乙二醇重氮树脂,用静电自组装并辅以紫外光照射的方法,在聚乙烯薄膜的表面引入了共价键连接的聚乙二醇分子链.用紫外-可见分光光度法研究了重氮树脂及其静电自组装体系的光分解性质,得到重氮基团的分解速率常数kd=0.021 4 s-1.红外分析表明,紫外光照射后聚乙烯薄膜表面连接的聚乙二醇分子链可耐DMF-ZnC l2-H2O三元极性溶剂的刻蚀.由于在聚乙烯薄膜的表面引入了亲水性的聚乙二醇分子链,其表面接触角从改性前的104°降至48°.; Hydrophilic PEG chains were introduced on HDPE film surfaces by the electrostatic self-assembly method via the electrostatic adsorption of PEG(polyethylene glycol) diazo-resin polycations on HDPE film surfaces which were pretreated by the concentrated chromic acid solution to produce carboxyl anions.Then the self-assembly monolayers were stabilized by covalence bonds formed from the decomposition of diazonium groups under ultraviolet irradiation.The photochemical decomposition of the diazonium groups was evaluated by the UV-visible spectroscopy method with a kd value of 0.021 4 s-1.The improved stability of the self-assembly monolayers with UV irradiation was identified by a solvent etching experiment of DMF-ZnCl2-H2O.The hydrophobic surfaces of HDPE films are hence hydrophilically modified with the contact angle decreasing from 104� to 48�.; 国家重点基础研究发展计划(973计划)资助项目(2003CB615701); 国家自然科学基金资助项目(20476045) |
