Reference electrodes that include a solid electron conductor; an interlayer; and a polymeric membrane layer comprising a polymer composition, the polymer composition comprising at least one silicone-containing polymer and at least one ionic liquid, wherein the polymeric membrane layer and the polymer composition are essentially plasticizer free and the silicone-containing polymer and the ionic liquid are miscible as determined using a thermodynamic method that shows a single glass transition temperature (T) of a composition including the at least one silicone-containing polymer and the at least one ionic liquid, wherein the interlayer is disposed between the solid electron conductor and the polymeric membrane layer. Also disclosed are electrochemical measurement systems including such reference electrodes.

Reference electrodes including silicone-containing polymer and ionic liquid

An electrochemical sensor with an ion-selective membrane that comprises a crosslinked alkyl methacrylate homopolymer or copolymer of two or more alkyl methacrylates 1. with a covalently attached electrically neutral or electrically charged ionophore that is selective for a target cation or anion, or 2. with a covalently attached cationic or anionic ionic site, or 3. with a covalently attached cationic or anionic ionic site and covalently attached electrically neutral or electrically charged ionophore.
