Abstract

An electrochemically active element is provided which comprises a first layer of PEDOT-PSS mixed with an adhesion promoter, and a second layer of PANI which is in direct electrical contact with said first layer. Such an element exhibits a substantially increased resistance from being overoxidized, as well as an electrical conductivity which is virtually the same as for pure PEDOT-PSS, and substantially better than for pure PANI. The electrochemically active element can be used in e.g. electrochemical pixel devices, transistors, diodes etc.
