Abstract

The invention discloses a conductive ink, a preparation method and a use method thereof. It is prepared from the following components by weight: 0.5-10 parts of PEDOT:PSS solution; 73.0-97.9 parts of solvent; 0.5-5.0 parts of polycarboxylic acid film-forming aid; 0.1-2.0 parts of organic silicon coupling agent; ethylene glycol Or 1.0-10.0 parts of DMSO. The invention has the advantages of high conductivity, good stability and high film strength.

Description

technical field [0001] The invention relates to a conductive ink, a preparation method and a use method thereof, and belongs to the field of conductive polymer functional materials. Background technique [0002] Poly-3,4-ethylenedioxythiophene (PEDOT) is a new type of conductive polymer material. The ethylenedioxy group introduced at the 3,4-position of the thiophene ring of PEDOT can effectively prevent the C α -C β The connection of the polymer chain makes the polymer molecular chain more regular and orderly, and its structural formula is as follows: figure 1 shown. However, the intrinsic state of PEDOT has poor electrical conductivity and is insoluble and infusible, which largely limits the application research of PEDOT in various fields. After poly(p-styrene sulfonate) anion (PSS) (its structure is as figure 2 Shown) doped PEDOT can be well dispersed in aqueous solution to form a stable PEDOT:PSS suspension, which can form a light blue PEDOT:PSS transparent conduct...
