The invention discloses a local in-situ electrochemical polymerization 3D printing method of a conductive polymer. The method comprises the steps of S100, uniformly mixing a conductive polymer monomer, an additive and a supporting electrolyte in a solvent for a 3D printer to prepare conductive polymer monomer dispersing liquid; S200, loading the conductive polymer monomer dispersing liquid into the 3D printer and applying voltage between a printing head and a conductive substrate; and S300, performing printing, allowing the conductive polymer monomer dispersing liquid to be printed by the printer layer by layer, and allowing the conductive polymer monomer to perform polymerization in a printing process to obtain a required conductive polymer product. The method is simple in technology, fewin procedure and high in production efficiency, is suitable for single or small-lot production, is also suitable for simultaneous large-lot 3D printing production of massive printers, and has a certain application prospect.

Description

Technical field [0001] The present invention belongs to the field of 3D printing (additive manufacturing), and specifically relates to a method of local in-situ electropolymerization 3D printing conductive polymer. Background technique [0002] 3D printing, also known as additive manufacturing, is a technology that manufactures three-dimensional products through layer-by-layer printing based on digital models. Because of its unique manufacturing method and huge manufacturing potential, it has received extensive attention and research from many research institutions and companies at home and abroad, and has been applied in medical, automotive, aerospace and other fields. In view of the difference between the printing targets of 3D printing and the printing materials, 3D printing is also subdivided into many types. Among them, the ink direct writing technology has obvious advantages in the printing of micro-electronic devices and micro-energy storage devices due to its wide range ...

Problems solved by technology

[0003] However, the subsequent heat treatment after ink direct writing has always been one of the main defects of ink direct writing technology, especially for conductive polymers, which are widely used in microelectronic devices and energy storage devices, the sintering process will not only make The volume and shape of the printed components change to a certain extent, which is not conducive to the precise molding of microelectrodes; at the same time, the high temperature of sintering will destroy the molecular structure of conductive polymers, causing them to lose or even lose their original electrical properties
