General description: | Carboxylated poly-vinyl chloride (PVC-COOH), is generally used in order to immobilize the potassium ion-selective and pH membrane electrodes. Carboxylated PVC-COOH membrane′s adhesive properties to an inert substrate such as polyimide-coated Kapton, can be greatly improved by reducing the plasticizer content of the membrane. |
