pH Surface Renewable Hydrogen Ion Electrodes Made of Composite of Nano-Iridium Oxide and Polymer Resin pH Sensor Using the Same and Preparation Method Thereof

摘要

A hydrogen ion electrode comprising a composite material of polymer resin and nano iridium oxide dispersed so that 1 to 10 nm of nano iridium oxide particles and / or agglomerates thereof are electrically connected to a thermoplastic and hydrophobic polymer resin matrix capable of being formed, a pH sensor using the same, A manufacturing method is provided. The pH of the surface of the hydrogen ion electrode is very fast and close to the ideality and the pH sensitivity of the surface of the sample exposed to the sample solution is very high and the pH sensitivity is very low due to high hysteresis and high physical strength Durability and high surface regeneration due to abrasion, thereby prolonging the life of the electrode, and can be easily manufactured in various sizes and shapes.
