Description

General description

Carbon/graphite screen printing paste is a carbon containing ink that can be used in the formation of working and counter electrodes. The electrode formed can be modified using an ionophore to obtain good cathodic peaks and cyclic voltammetric values. These electrodes can further be used in the fabrication of electrochemical devices.[1][2]

This product is designed to be used for screen-printing working electrodes. This ink has been optimised to give superior electrochemical performance. It combines good line definition and good electrochemical performance with good reversibility when using cyclic voltammetry.

Application

Carbon/graphite screen printing paste can be coated on flexible substrates for the formation of electrochemical sensors for biological detection.[1][2][3][4]

Features and Benefits

This ink can be used in conjunction with UV dielectrics and ink is fast drying.
