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 In (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 =.002.
