| 摘 要： | 以甲苯二异氰酸酯(TDI)为原料,分别与长、短链醇进行加成反应制备氨基甲酸酯基水分蒸发抑制剂(CM),考察分子膜在气液界面的铺展性能、蒸发比阻、抑制率、表面电流以及AFM图像.研究结果表明:CM(7∶3)、CM(6∶4)和CM(4∶6)水分蒸发抑制剂具有较好的铺展性能,其中CM(7∶3)分子膜的蒸发比阻最大,在温度高于30℃时依然保持良好的抑制水分蒸发效果.分子膜的表面电流以及AFM图像表明CM(7∶3)能在气液界面形成致密的分子膜,铺展平衡时分子膜的表面结构稳定.

| Abstract: | Carbamate based water evaporation inhibitors were prepared with TDI as a raw material which was interacted with long and short chain alcohols. Its spreading properties, evaporation resistance, inhibition ratio, surface current and AFM images of the monolayers at the gas/liquid interface were investigated subsequently. The results of the research showed that the water evaporation inhibitors CM （7 ： 3）, CM （6 ： 4）and CM （4 ： 6）had the better spreading properties, and the carbamate based water evaporation inhibitors still kept the restrain effect when temperature was over 30 ℃. The surface current and AFM images of the monolayers indicated that the carbamate based water evaporation inhibitors could form compact monolayers, and the monolayers＇ surface structures were stable while they were spread evenly. |
