Mesomolecular Anilines*: New Horizons in Electrically Conducting Organic Materials
MacDiarmid, University of Pennsylvania
Technology Issues: (i) New Grant: Polyaniline has a conductivity ~104 smaller than its projected intrinsic value which approaches |
||
Objectives: (i) New Grant: Study mesomolecular anilines with particular emphasis on their isomeric forms--forms which are predicted to control the conductivity of polyaniline. Evaluate new, unexpected properties of oligomers. (ii) Old Grant: Determine properties of polypyrrole films as a function of thickness and application as electrodes. |
||
Approach: a) as a function of thickness. b) as electrodes on poly(VDF-TrFE). |
Accomplishments: |
|
Impact & Transition: In-situ deposited polypyrrole electrodes show very considerable promise in electro-acoustic applications. |
*A mesomolecular aniline is an oligomer of aniline (short chain aniline) in which the band structure of polyaniline is approaching complete development
