Method for producing water-repellent film |
摘要 |
A method for forming a water-repellent film on a solid substrate. The method includes: preparing a mixed solution of a silane coupling agent (A) including reactive functional groups at both ends and a hydrocarbon chain and a benzene ring in the middle part; a silane coupling agent (B) including a fluorocarbon chain at one end and a reactive functional group at another end; and a chemical material including at least an organic solvent, water and acid catalyst; allowing hydrolysis and dehydration polymerization reaction of the silane coupling agents (A) and (B) to proceed; diluting the solution; applying the solution to the substrate and heating the substrate, thereby forming a polymer film of the silane coupling agent (A) and the silane coupling agent (B). Thus, there is provided a method for producing an alkali resistant water-repellent film at low cost.
