Abstract

The invention discloses an AZO transparent conductive film paint, glass plated with the paint and preparation methods thereof. The paint consists of a nano zinc oxide crystal doped with one or more metal ions selected from aluminium ion, tin ion, copper ion, molybdenum ion, titanium ion, vanadium ion, cerium ion, yttrium ion and magnesium ion. A surface of regular glass or ultra-white float glass is plated with the paint through an electrostatic spraying to form a transparent conductive film, so as to obtain an AZO glass, which can be arranged on a solar film cell and a flat-panel display. The prepared transparent conductive film has high conductivity, high transmittance, controllable haze and strong aging resistance capability.

Description
