Substrates having free surface hydroxyl groups, such as silaceous and aluminous materials, are rendered corrosion resistant by the application thereto of an amorphous, homogeneous tantalum pentaoxide coating layer.

Corrosion resistant tantalum pentaoxide coatings

A method of making an electrically conducting polymer is disclosed which includes poly(N-alkyl 3',3 carbazolyl) at least a portion of which is doped with a compatible charge transfer acceptor to provide p-type electrical conductivity, and in which the alkyl group is one selected from the group consisting of ethyl and methyl or a combination thereof.
