TITANIUM OXIDE COATING AGENT, AND METHOD FOR TITANIUM OXIDE COATING FILM FORMATION

摘要

This invention provides a coating agent, which can simply form a coating film over a wide area, is chemically and physically stable, and can form an ultrathin film, a coating film, a method for coating film formation, and various products coated with the coating film. The coating agent contains flaky titanium oxide fine particles prepared by subjecting a layered titanate to ion exchange treatment with an alkylammonium. The coating agent may comprise a solution containing a titania nanosheet and a sol of silicon oxide or titanium oxide. The coating film is formed by conducting coating and then drying and heating the coating and has a microstructure in which flaky titanium oxide fine particles are stacked with a high level of orientation.
