Abstract:
1. A process for producing a porous film on a substrate, comprising (a) applying a 0.5 to 50 nm-thick film of an alucone, zinc-ethylene glycol hybrid polymer, or titanium-ethylene glycol hybrid polymer to at least a portion of the surface of a substrate via an atomic layer deposition process, and (b) forming pores in the hybrid film by oxidizing the hybrid film by heating the film in the presence of air or oxygen at a temperature of at least 400° C. to burn out the organic portion of the alucone, zinc-ethylene glycol hybrid polymer, or titanium-ethylene glycol hybrid polymer or by contacting the film with water to hydrolyze the alucone, zinc-ethylene glycol hybrid polymer, or titanium-ethylene glycol hybrid polymer and remove the organic portion of the film.
