Abstract:
Patterned conducting polymer surfaces exhibiting excellent properties may be prepared by: (a) forming a surface of a conducting polymer on a surface of a substrate; (b) forming a surface of a blocking material on said surface of said conducting polymer in a pattern-wise fashion, to obtain a first patterned surface containing regions of exposed conducting polymer and regions of blocking material; (c) treating said first patterned surface with an agent which: (i) removes said conducting polymer from said regions of exposed conducting polymer; (ii) decreases the conductivity of said conducting polymer in said regions of exposed conducting polymer; or (iii) increases the conductivity of said conducting polymer in said regions of exposed conducting polymer; and (d) removing said blocking material to obtain a second patterned surface containing an exposed pattern of conducting polymer.
