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 exhibits a remarkable and reversible hydrophobic-hydrophilic transition depending on temperature high response rate. static water contact angle of the decreases 103° ± 2° to 60° 1° as increases 30 °C 80 °C. Further, UCST-type shows positive linear relationship between temperature. This study for first time provides that by over 35° only 20
