Multilayer charging film coating preparation method

The invention discloses a multilayer charging film coating preparation method. The method includes: a first coating step, to be more specific, coating a glass plate with a conductive organic polymer solution, wherein the solution comprises 0.001-0.1wt% of polysulfonated styrene doped polyethylenedioxy thiophene and silicon alkoxide with the weight percentage being smaller than 5wt%; a second coating step, to be more specific, spreading siloxane Si(OR)4 after the first coating step is finished. The invention aims to provide a high-conductivity film coating, such as an image display screen coating; a high-conductivity film can be made by conductive organic polymers at a low cost according to a simple method and has improved static electricity resistance performance and high film hardness and bonding strength. The method includes steps for acquiring an antistatic film layer, and the steps include dissolving the conductive organic polymer solution into ethyl alcohol, spreading a solution obtained after dissolution, performing spin coating of an ethanol solution of siloxane, and subjecting the film layer obtained after spin coating to heat treatment.
