Glass plate having electrically charge-preventive film of conductive organic polymer, its making method, a solution for making the film, and its manufacturing method

摘要

A glass plate having high-electroconductive film which can be formed using electroconductive organic polyrmer in a simple method and at a low cost, and having an improved anti-static characteristic with a strong film hardness and a strong adhesive strength. The glass plate has an anti-static film (10, 20) formed on the exterior surface, the film comprising a first coating layer (11, 21) formed containing an electroconductive organic polymeric component and a second coating layer (12, 22) of silica coating formed by being overcoated onto the first coating layer (11, 21). The electroconductive organic polymeric solution contains 0.005-0.5 wt. % of polyethylenedioxythiophene which polystyrenesulphonate is doped to and silicon alkoxide of below 10 wt. %, and also may contain 40-90 wt. % of at least one a selected from a group consisting of a methanol, an ethanol, an isopropanol, a butanol, and combinations thereof, 5-70 wt. % of pure water, and 1-20 wt. % of at least one co-solvent selected from a group consisting of a compound having a carbonyl group, an ether, and combinations thereof.
