Nanopin film is an experimental material in nanotechnology developed in 2005 with unusual superhydrophobic properties . A droplet of water makes contact with the surface of this film and forms an almost perfect sphere with a contact angle of 178°. This happens because it is covered with nanoscale, topped-off pins or cones perpendicular to the surface. The surface is regarded as a composite material with mostly air and a small fraction constituted by the tops of the cones. When the contact angle of the cone material is sufficiently large, Cassie's law predicts large contact angle values for the composite.
