Conductive polymer coating with improved aging stability

摘要

The invention relates to a member comprising a substrate and a transparent conductive layer comprising an electronically conductive polythiophene polymer present in a cationic form with a polyanion, wherein said conductive polymer has an FOM less than or equal to 50 wherein FOM is defined as the slope of the plot of ln (1/T) versus [1/SER]: and wherein T=visual light transmission SER=surface electrical resistance in ohm per square FOM=figure of merit, and wherein the SER has a value of less than or equal to 1000 ohm per square and wherein said transparent conductive layer has an ASI (aging stability index) of <=0.002.
