Abstract

The invention discloses an ink printing process-based preparation method of a carbon electrode. The method is characterized by comprising the following steps of (1.1) mixing a carbon material with a poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) dispersion liquid doped with a complex acid to obtain doped PEDOT:PSS dispersion liquid-based conductive carbon paste; (1.2) stirring the doped PEDOT:PSS dispersion liquid-based conductive carbon paste obtained in the step (1.1) to obtain sample conductive carbon paste, and uniformly scraping and attaching the conductive carbon paste obtained in the step (1.2) on a pretreated glass substrate by use of a scraper method to obtain the glass substrate which uniformly covers the conductive carbon paste; and (1.3) carrying out heat treatment of the carbon electrode, carrying out constant-temperature heating treatment on the glass substrate which uniformly covers the conductive carbon paste and is obtained in the step (1.2), and naturally cooling to a room temperature to obtain the carbon electrode, wherein the constant-temperature heating temperature range is 40-130 DEG C and the heating time is 1-15 minutes.

Description

technical field [0001] The invention relates to the field of organic optoelectronic technology materials, and relates to a method for preparing a carbon electrode based on an ink printing process. Background technique [0002] Conductive carbon paste is a conductive ink made by uniformly distributing carbon-based particles of non-metallic conductor materials in a solvent through an organic or inorganic dispersant. Conductive carbon paste is an intermediate product. After being applied by a scraper and cured at a certain temperature for a period of time, a conductive film layer is obtained. [0003] The conductive carbon paste has stable performance, corrosion resistance and oxidation resistance, and the ink has strong adhesion and is not easy to peel off. It can be well combined with metal, glass cloth board and VC, PET and PC sheets. [0004] At present, many conductive pastes on the market are metal pastes (conductive silver paste, etc.), but such metal pastes are expensi...
