Abstract
Articles including a polymeric substrate and an electrically conductive surface are provided. Methods of making and using such articles also are provided.
Claims34
An article comprising:
- a polymeric substrate;
- and
- an electrically conductive coating disposed on at least a portion of the substrate and having a projected surface area and a topographical surface area wherein the topographical surface area is greater than the projected surface area, wherein the coating comprises at least one electrically conductive polymer that composes at least one moiety having π-electron delocalization.
An array comprising:
- an article that comprises a polymeric substrate and an electrically conductive coating disposed on at least a portion of the substrate, and having a projected surface area and a topographical surface area wherein the topographical surface area is greater than the projected surface area, wherein the coating comprises at least one electrically conductive polymer that comprises at least one moiety having π-electron delocalization;
- and
- one or more reactants affixed to the electrically conductive coating.
A method of making a coated article, the method comprising:
- providing a shrinkable polymeric substrate;
- coating at least a portion of the polymeric substrate with a dopant;
- permitting a monomer to contact the dopant, thereby forming an electrically conductive coating;
- and
- shrinking the substrate.
2 more elements
An article comprising:
- a polymeric substrate;
- and
- a polymeric coating comprising at least one electrically conductive polymer disposed on at least a portion of the substrate and having a projected surface area and a topographical surface area wherein the topographical surface area is greater than the projected surface area, wherein the electrically conductive polymer comprises acetylene, a polyacetylene, or a substituted analog thereof.
An array comprising:
- an article that comprises a polymeric substrate and a polymeric coating comprising at least one electrically conductive polymer disposed on at least a portion of the substrate and having a projected surface area and a topographical surface area wherein the topographical surface area is greater than the projected surface area, wherein the electrically conductive polymer comprises acetylene, a polyacetylene, or a substituted analog thereof;
- and
- one or more reactants affixed to the electrically conductive coating.
