Abstract
An electrically conductive polymeric composition is fabricated by dispers polymeric ether complexes of TCNQ salts within a flexible, thermoplastic polymer matrix. The compositions form flexible, homogeneous, films which exhibit substantially superior properties over currently available TCNQ salt based systems.
Claims6
A flexible, film-forming, electrically conductive polymeric composition consisting of a thermoplastic polymer matrix having dispersed therein an effective amount of a complex represented by the formula:
- [E.multidot.(M.sup.n+)][TCNQ ].sub.n TCNQ.degree..sub.m
- wherein n is 1 or 2, m is o or 1, TCNQ is 7,7,8,8 tetracyanoquinodimethane, M is an alkali metal, alkaline earth metal, or ammonium, and E is a polymeric ether selected from the class consisting of poly(ethylene oxide), polyoxethane, polytetrahydrofuran, poly(vinyl ethers), polyphenylene oxide, polydioxalan, and mixtures thereof.
