[0017] First, the pretreatment of the glass substrate, the glass substrate is treated with a strong oxidant. Treatment method: place the glass substrate in V (98% concentrated sulfuric acid): V (30% H 2 o 2 )=1:1 solution at room temperature for 1 hour, then ultrasonic cleaning with deionized water for 20 minutes, and then immersing the substrate in V(H 2 O): V(H 2 o 2 ):V (25% concentrated ammonia water)=5:1:1 solution soaked for 1 hour, then ultrasonically cleaned with deionized water for 20 minutes, placed in a dust-proof device and dried in an oven. The drying temperature has no special requirements. First immerse the treated glass substrate in the positively charged polydiallyl dimethyl ammonium chloride solution for 15 minutes, take it out and rinse and dry it with a large amount of deionized water; then immerse it in the negatively charged polystyrene sulfonic acid Sodium solution for 15 minutes, take out and rinse with a large amount of deionized water and dry, rep...
