    摘要： Solid state conductive polymer compositions which are ionically-conductive regardless of the amount of water present in the composition are disclosed. The compositions have solvating polymer, ionic salt, and optionally if the composition is not cohesive and pliable, essentially non-volatile plasticizer in an amount sufficient to render the composition cohesive and pliable. Biomedical electrodes having means for electrical communication contacting the compositions are also disclosed. Methods of making the compositions and electrodes are also disclosed.

    摘要： The present invention discloses a low impedance, water-absorbing, ionically-conductive, hydrophilic pressure sensitive adhesive composition comprising an ionically-conductive, hydrophilic, pressure sensitive adhesive hydrogel and crosslinked poly(N-vinyl lactam) in an amount sufficient to retain low electrical impedance and maintain hydrogel adhesion and cohesion during use of the composition in the presence of water and other moisture tending to plasticize the hydrogel. Crosslinked homopolymers and copolymers of poly(N-vinyl pyrrolidone) having Swelling Capacity of at least 15 milliliters of water per gram of poly(N-vinyl pyrrolidone) are preferred. Adhesion values upon removal from mammalian skin after about four hours of adhesion are not greater than initial adhesion removal values, demonstrating ease of removal of electrodes of the present invention from skin.

    摘要： A composite article is prepared comprising in sequence a fibrous polymeric support which has been subjected to a surface treatment to provide binding sites thereon, a layer of a protein immobilizer compound, and a biologically active protein. The surface treatment comprises coating the support with a 2 to 500 nm thick layer of inorganic oxide or subjecting the support to a plasma treatment. The protein immobilizer can be a polymer or silane-functional compound. The biologically active protein can be the enzyme, catalase, which has use in decomposing hydrogen peroxide when disinfecting contact lenses.
