The post structure ACNT film showed discrete pillar composed of carbon nanotubes, these pillar formed microstructure in the film, which affected both the contact angle and the sliding angle.展开更多

The contact angle for water of the films is 161°. The films modified with fluoroalkylsilane show a better hydrophobic property. The contact angle for water of the modified films is as high as 172°. The alignment structure of the films and large fraction of air on the films are considered to be responsible for the ultrahydrophobic property.展开更多

Super-hydrophobic surface[with water contact angle(CA) larger than 150°] have been extensively investigated due to their importance for industrial applications. In the present study, we describe a rather simple method for synthesizing separated alignments of polymer nanopole films, which has super-hydrophobic property with water a contact angle as high as 152.0°. Nanostructures that induce the large fraction of air on the surface cause this unique property.展开更多
