ELECTRICALLY ACTIVE POLYMER AND MATERIAL BUILT AROUND IT Russian patent published in 2005 - IPC

FIELD: electrical engineering; physical action-to-electric signal converters: strain-gage components, pressure sensors, push-button switches for handling electric signals.

SUBSTANCE: proposed electrically active polymer whose electrical activity depends on impact of external physical fields has molecular fragments possessing high polarizability and/or bistable electron energy structure with respect to excess electron capture process; molecular fragments are linked together through respective intermediate elements of molecular chain. Novelty is that electrically active molecular fragments form single macromolecular structure chemically bonded through molecular chains. Proposed material built around mentioned polymer is produced in the form of films or fibers, or coatings, or bodies of revolution; at least one of geometrical dimensions dictating material form does not exceed double depth of surface charge penetration.

EFFECT: enhanced response of material electric conductivity to external factors within wide film-thickness range; high reproducibility of useful properties.
