Abstract:
A method for producing an alignment chemisorption monomolecular film comprising a process (A) and a process (B),said process (A) comprising the step of forming a monomolecular film by chemisorption on a hydrophilic surface of a base material by bringing the hydrophilic surface into contact with a silane-based surfactant having a carbon chain or a siloxane bond chain so as to cause a chemical reaction between them, thereby bonding one end of the surfactant molecules to the hydrophilic surface, andsaid process (B) comprising the steps of orienting the base material with the monomolecular film in a predetermined orientation,vapor-washing said oriented base material with vapor of an organic solvent, andperforming a first alignment of the surfactant molecules constituting the film by flow of condensation of the vapor on the film.
