Metal oxide pH sensor

摘要

A pH sensor comprising a metal oxide-polymer composite, comprising: a continuous polymer resin matrix and a solid particulate component dispersed in the polymer resin matrix comprising (i) metal oxides and (ii) a particulate carbon-based conductor wherein the metal oxides comprise Ta20s and RuO 2 in a weight ratio of Ta2 0. RuO 2 (on the basis of weight of metal component) in the range of from 90:10 to 10:90
