Fabrication of Polymer-Ag Honeycomb Hybrid Film by Metal Complexation Induced Phase Separation at the Air/Water Interface

A new facile approach for the fabrication of polymer-Ag honeycomb film is reported. A polymer-Ag+ honeycomb thin film is obtained by casting a CHCl3 solution of a functional graft copolymer on aqueous silver nitrate solution, leading to metal complexation induced phase separation at the air/water interface. The film is reduced by UV irradiation to give a polymer-Ag honeycomb film with regular morphology. Pyrolysis of the film gives a translucent Ag honeycomb film.
