Claims
- 1. A method comprising: providing a precursor to an electrically conductive polymer; said precursor being polyaniline having cross-linkable functionality;cross-linking said polyaniline to form a cross-linked polyaniline precursor; and exposing said polyaniline cross-linked precursor to a dopant to dope said cross-linked precursor to the conductive state; wherein said dopant further includes a solvent solvation enhancing functionality.
- 2. A method according to claim 1 wherein said precursor is selected from the group consisting of a polyaniline and a copolymer thereof and wherein said electrically conductive polymer is selected from the group consisting of an electrically conductive polyaniline and copolymer thereof, said precursor and said electrically conductive polymer contain a hydroxyalkyl group which provides solvent solvation enhancing functionality and said crosslink functionality.
- 3. A method according to claim 1 wherein said cross-link functionality sufficiently overcomes steric constraints of said solvent solvation functionality by holding adjacent precursor molecules sufficiently close together that the doped form of said precursor has an increase in electrical conductivity as compared with the undoped form of said precursor.
- 4. A method according to claim 1, wherein said cross-linked polyaniline is cross-linked through a dopant selected from the group consisting of a protonic acid having pendant hydrogen bonding functionality, protonic acid having pendant chemical cross-linkable functionality, non-protonic acid having pendant hydrogen bonding functionality and non-protonic acid having pendant chemical cross-linkable functionality.
- 5. A method comprising: providing a precursor to an electrically conductive polymer; said precursor being polyaniline having cross-linkable functionality;cross-linking said polyaniline to form a cross-linked polyaniline precursor; and exposing said polyaniline cross-linked precursor to a dopant to dope said cross-linked precursor to the conductive state; said polyaniline cross-linked precursor is cross-linked through a dopant selected from the group consisting of a protonic acid having pendant hydrogen bonding functionality, protonic acid having pendant chemical cross-linkable functionality, non-protonic acid having hydrogen bonding functionality and non-protonic acid having pendant chemical cross-linkable functionality.
