<p>Substrate carrying a mixed organic conductive polymer/transparent metal oxide coating having a thickness between 100 and 600 nm. The conductive polymer polyethylene-dioxythiophene (PEDOT) is an interesting material to reduce the alternating electric field (AEF) emitted at the front of a colour monitor tube. The processing of the PEDOT is based on chemical polymerisation of ethylenedioxy-thiophene (EDOT) and Fe (III) toluene sulphonate on a face plate of the tube. After the polymerisation is completed, the Fe salt is extracted from the coating by rinsing with an ethanolic solution. If TEOS is used, a hybrid PEDOT/SiO2 film is formed. The specific conductivity is 120 S/cm and the average transmission (380-780 nm) 80 % for a layer thickness of about 300 nm.</p> |
