Using the method of ball milling dispersion,and the ITO slurry was prepared by the dispersion of ITO stive in anhydrous ethanol system.After that,the ITO slurry was combined with the PVB resin,disper-sant of PVPK30 and isopropyl alcohol to prepate the ITO/PVB paint.At last,ITO/PVB glass was prepared by filming on the matrix glass.By using the UV-visible spectrophotometer in the visible light transmittance of the coating,UV and infrared light absorption rate was characterized,analysised and tested,scanning e...
