Abstract
A sharp surface wettability transition with varying film thickness dependent morphology was observed in cast films of an amphiphilic triblock copolymer comprised of poly(2-(N-ethylperfluotooctanesulfonamido) ethyl methylacrylate), poly(FOSM), and poly(N,N'-dimethylacrylamide), poly(DMA). Films with thickness (h) in the range, 200 nm c ''6 ° to 40 ° in 3-4 s. Relatively shallow decreasing water contact angle (θw) gradients were observed around this transitional film thickness for films in the overall range of 40 nmCitation
