Nanopin film

Nanopin film

It 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 1780. The film is covered with nanoscale topped off pins or cones perpendicular to the surface. This particular nanopin film is produced with borosilicate glass as the primary substrate.

A solution of CoCl2•6H2O or cobalt chloride hexahydrate is heated at 60 °C for 24 hours in a chemical bath deposition to form a brucite type cobalt(II) hydroxide layer.
