A smart surface with converse temperature-dependent (CTD) wettability was fabricated from an upper critical solution temperature-type (UCST-type) poly(acrylamide-co-acrylonitrile) (P(AAm-co-AN)) copolymer. The obtained surface exhibits a remarkable and reversible hydrophobic-hydrophilic transition depending on temperature with a high response rate. The static water contact angle of the surface decreases from 103° ± 2° to 60° ± 1° as the temperature increases from 30 °C to 80 °C. Further, the wettability of the UCST-type surface shows a positive linear relationship between wettability and temperature. This study for the first time provides an UCST-type smart surface with wettability that decreases by over 35° as the temperature increases by only 20 °C.

基于聚（丙烯酰胺-丙烯腈），构建具有相反温度依赖性润湿性的智能表面。

由上临界溶液温度型（UCST型）聚（丙烯酰胺-丙烯腈）（P（AAm-co-AN））共聚物制成具有逆温度依赖性（CTD）润湿性的智能表面。所获得的表面显示出显着且可逆的疏水-亲水转变，这取决于温度并具有高响应速率。随着温度从30°C增加到80°C，表面的静态水接触角从103°±2°减小到60°±1°。此外，UCST型表面的润湿性在润湿性和温度之间显示正线性关系。这项研究首次为UCST型智能表面提供了可湿性，当温度仅增加20°C时，其润湿性降低了35°以上。
