Abstract

The present invention provides a chemical adsorption solution prepared by dissolving a silane-based chemical adsorption material in a non-aqueous organic solvent, in which the non-aqueous organic solvent is a mixture including a first non-aqueous organic solvent and a second non-aqueous organic solvent having a boiling point higher than that of the first non-aqueous organic solvent. A preferable difference in the boiling point is at least 10 DEG C. Preferably, the first non-aqueous organic solvent has a boiling point of not more than 120 DEG C. and the second non-aqueous organic solvent has a boiling point of not less than 150 DEG C. The chemical adsorption solution coated on a substrate is concentrated by evaporating the solvent having the lower boiling point, so that a chemically adsorbed film having a uniform film thickness can be formed in a short time.

Description

technical field [0001] The invention relates to a preparation method of a monomolecular film. The present invention also relates to a method for preparing a liquid crystal alignment film for a liquid crystal display device composed of a monomolecular film. Background technique [0002] Chemical adsorption can be used to form films at the molecular length level with functions such as hydrophobicity, oleophobicity, and antifouling properties. Therefore, the development of chemical adsorption membranes for a wide range of applications such as waterproof membranes and protective membranes is expected. [0003] As a method for forming a monomolecular film, the Langmuir-Blegett method (hereinafter referred to as the LB method) is widely known. The LB method uses the properties of amphiphilic organic molecules on the water surface to make the hydrophilic group a downward monomolecular film, and transfers the monomolecular film formed on the water surface to a solid substrate to f...
