RESIN FILM FORMATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a resin film formation method with high reliability where a resin film is closely bonded on an inorganic material.SOLUTION: A resin film formation method comprises the steps of: introducing a carboxyl group or an amino group on the surface of an inorganic material; forming a resin film containing a resin consisting of one of a thermosetting resin and a thermoplastic resin or a combination thereof on an inorganic material introduced with the carboxyl group via a silane coupling agent; adjusting a hydroxyl group density on the surface of the inorganic material to be 4-8 groups/nm; and forming the resin film containing the resin consisting of one of the thermosetting resin and the thermoplastic resin or a combination thereof on the inorganic material adjusted with the hydroxyl group density via a silane coupling agent.
