LEAK-FREE REFERENCE ELECTRODE WITH NANO-POROUS PROTECTIVE MEMBRANES

摘要

The present invention provides a solid state reference electrode comprising; polymeric substrate, silver materials, silver chloride materials; and nano-porous hybrid solgel materials doped with chloride salts and borate compounds. The present invention also provides a method for preparation of solid hydrogel comprises the steps of: (a) mixing tetraethyl orthosilicate, methyltriethoxysilane, deionized water, and hydrochloric acid; (b) stirring and mixture until a clear homogeneous mixture is achieved; (c) adding lithium chloride and trimethyl borate to the homogeneous mixture; (d) sonicating the mixture of step (c).
