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 faceplate of the tube. After the polymerisation is completed, the Fe salt is removed out of the coating by use of a TEOS solution. During this process, a hybrid PEDOT/SiO 2 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.
