ELECTRICALLY CONDUCTIVE POLYMER THICK FILM OF IMPROVED WEAR CHARACTERISTICS AND EXTENDED LIFE

摘要

the invention relates to a composition for u00e9lectroconducteur polymer film (10), which includes a polymer resin, a substance u00e9lectroconductrice intimately mixed with the polymeric resin in an amount sufficient to render the polymer resin particle and u00e9lectroconductrice. (16) such that the fibres or areas of relevant quantities.the composition is mixed with the polymer in an amount sufficient to particles contained in the polymer film on the surface of rubber to projection (14) of the film and make the uneven surface on the scale of microns.this composition is incorporated in the vulcanized polymer film potentiometers and electrical devices and the like in the form of a thick film through a brush contact (18) which is essentially continuous protruding fibres.the potentiometers in which is incorporated a thick layer has a polymer film useful life considerably expanded, extending generally from several million cycles of motion of the brush to contact the film.
