PURPOSE: A transparent conductive hard coating film is applied to computers, television Braun tube glass surface, clean room's wall, hand carrier surface, CPP and PET film and PC and PMMA panel surface, portable telephone housing and PVC resin with good conductivity and transparency. CONSTITUTION: The hard coating film comprises a laminated coating of a polythiopene-based solution and a silica sol solution on a substrate. The polythiopene-based solution is prepared by mixing at least one solvent selected from the group consisting of alcohol, aldehydes and ketones with an aqueous or alcohol soluble polymer in an amide solvent. The silica sol solution is prepared by hydrolyzing and condensing silane compounds having three and four functional groups with an organic coupling agent. The substrate is selected from the group consisting of glass, polymethamethylacryl resin, polyacryl resin, polycarbonate resin, PET resin and PVC resin. The polyethylenedioxythiopene is doped with polystyrene sulfonate. The solvent is at least one selected from the group consisting of lower alcohol having one to four carbon atoms such as methanol, ethanol, propanol, isopropanol or acetaldehyde represented by the formula 1, and ketones such as acetone, methyl ethyl ketone or methyl isobutyl ketone. Formula 1:R1-C(O)-R2 (wherein R1 is H or C1-C10 alkyl or aryl; and R2 is C1-C10 alkyl or aryl). |
