研究了两亲性含氟聚合物poly(N-1H，1H-pentadecafluorooctylmethacrylamide)，(PC7F15MAA)薄膜的表面润湿性。采用两种自下而上的方法：Langmuir-Blodgett法制备了纳米结构含氟聚合物pC7F15MAA薄膜。PC7F15MAA LB膜表面非常光滑，表面粗糙度为1.16 nm，表面的水接触角为118°，表明表面被CF3基团占据。Dropcast提供了表面粗糙度为230 nm、WCA为163°的pC7F15MAA纳米颗粒组件。结果表明，用两亲性含氟聚合物自下而上的方法可以有效地构建纳米结构，从而控制表面润湿性。
The surface wettability of amphiphilic fluorinated polymer poly(N-1H,1H-pentadecafluorooctylmethacrylamide), (pC7F15MAA) films was investigated. Nanostructured fluorinated polymer pC7F15MAA films were prepared using two bottom-up methods: Langmuir–Blodgett technique and dropcasting. The pC7F15MAA LB films show quite smooth surfaces as low as the surface roughness of 1.16 nm, and the surface has a water contact angle (WCA) of 118°, indicating that the surface is occupied by the CF3groups. Dropcasting provides pC7F15MAA nanoparticle assemblies with the surface roughness of 230 nm and a WCA of 163°. Results imply that bottom-up approaches with amphiphilic fluorinated polymer are effective to construct nanostructures, thereby controlling the surface wettability.
