A conductive adhesive composition is provided and articles that include the adhesive composition as a component thereof. The conductive adhesive composition comprises: (a) pressure sensitive adhesive; (b) electrolyte comprising water soluble or water dispersible organic chloride; and (c) humectant. In some embodiments, the conductive adhesive composition is a bicontinuous composition comprising an aqueous phase and an oil phase, and the bicontinuous composition may be derived from a polymerizable microemulsion composition, the microemulsion composition comprising: an aqueous phase comprising one or more hydrophilic monomers or oligomers and/or one or more amphiphilic monomers or oligomers in water, the water-soluble or water- dispersible organic chloride, surfactant and humectant; and an oil phase comprising one or more hydrophobic monomers or oligomers. Biomedical articles such as biomedical electrodes, may incorporate the foregoing adhesive as a component.
La présente invention concerne une composition d'adhésif conducteur ainsi que des articles utilisant cette composition d'adhésif. La composition comprend: (a) de l'adhésif autocollant; (b) de l'électrolyte à base de chlorure organique hydrosoluble ou hydrodispersable; et (c) de l'humectant. Dans certains modes de réalisation, la composition d'adhésif conducteur est une composition bicontinue à phase aqueuse et phase huileuse. La composition bicontinue peut provenir d'une composition de microémulsion polymérisable, laquelle composition de microémulsion comprend: une phase aqueuse comprenant un ou plusieurs monomères ou oligomères hydrophiles et/ou un ou plusieurs monomères ou oligomères amphiphiles dans l'eau, le chlorure organique hydrosoluble ou hydrodispersable comprenant un ou plusieurs monomères ou oligomères hydrophobes. Des articles biomédicaux tels que des électrodes biomédicales peuvent intégrer les adhésifs de l'invention en tant que composant.
