Title:
TRANSPARENT THIN FILM OF TRANSITION METAL OXIDE HAVING A LARGE DIAMETER NANO-SPACES, METHOD FOR PRODUCING SAME AND DYE-SENSITIZED DEVICE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2011/114998
Kind Code:
A1
Abstract:
Disclosed is a method for producing a transparent thin film of a transition metal oxide wherein large pores with a diameter in the range of 30 - 150 nm that can handle biologically relevant molecules selectively and in large volumes are present, and the connecting pores therefor are of a size that biologically relevant molecules can pass through. This method is characterized in that, after mixing of a surface active agent, which is constituted by block copolymerization of a polyoxyethylene unit that plays a hydrophilic role and a polystyrene unit with a degree of polymerization in the range of 300 - 4000 that plays a hydrophobic role, a metal salt of titanium, tin or zinc and a precursor transition metal oxide having one or more metal alkoxides as an inorganic starting material and after film growth, the surface active agent is eliminated. Also disclosed is the transparent thin film.
