Abstract

The invention discloses a CNT:SNC:PEDOT ternary water-based conductive ink and a preparation method thereof. The method comprises the following steps: adding carbon nanotubes into a sulfated nanocellulose aqueous dispersion, and conducting uniform dispersing to obtain a CNT:SNC dispersion; adding an EDOT monomer into the CNT:SNC dispersion, and conducting uniform stirring to obtain a mixed liquid;and adding ammonium persulfate and ferric chloride into the mixed solution, and carrying out polymerization reaction in an inert atmosphere to obtain the CNT:SNC:PEDOT ternary water-based conductiveink. The CNT:SNC:PEDOT ternary conductive ink has the advantages of being water-based, environment-friendly, good in stability, good in adhesive force, free of heating curing, high in universality andthe like. Meanwhile, due to the advantages of stable dispersion, high conductivity, excellent printing adaptability, excellent coating mechanical stability and the like, the conductive ink provided by the invention is expected to be applied to printing of various flexible electronic devices.

Description

technical field

[0001] The invention belongs to the field of conductive ink, and mainly relates to a CNT:SNC:PEDOT ternary water-based conductive ink and a preparation method thereof. Background technique

[0002] Conductive ink refers to the ink that is printed on conductive substrates to enable it to conduct current and eliminate the ability to accumulate static charges. It is generally printed on non-conductive substrates such as plastic, glass, ceramics or cardboard. As a key material used in printed electronic technologies such as radio frequency identification technology, flexible printed circuits, sensors, electromagnetic shielding, membrane switches and e-books, conductive ink has attracted widespread attention for its application advantages and research results. Conductive inks are generally composed of conductive fillers, binders, solvents and various auxiliary agents, among which conductive fillers are the key phase of ink conductivity. Conductive fillers include...
