Abstract
The invention discloses a kind of water-based UV electrically conductive inks and preparation method thereof, on the basis of the gross weight of the electrically conductive ink, it is made up of the component of following weight/mass percentage composition：40~60% conducting polymer PEDOT, 10~30% deionized water, 1~8% oxidant, 10~20% copper nanoparticle, 0.2~1.2% stabilizer, 2~5% adhesive, 1~6% levelling agent, 0.2~1.2% defoamer, 0.2~2% polymerization inhibitor and 10~30% solvent.Using technical scheme, due to preparing electrically conductive ink using the conducting polymer PEDOT and Nanometer Copper of relative low price, cost and simple to operate is greatly reduced, it is easy to accomplish industrialized production；Technical scheme need not only simplify technique to ink progress high temperature sintering in printing process while improve the stability and uniformity of electrically conductive ink simultaneously.
Description
Technical field
The invention belongs to macromolecule conducting material field, more particularly to a kind of water-based UV electrically conductive inks.
Background technology
Water-based UV (ultraviolet light solidification) electrically conductive ink is a kind of novel ink developed in recent years, water-based UV ink settings speed
Degree is fast, and environmental pollution is low, and energy resource consumption is few, turns into the universally recognized novel ink kind of current ink industry, is mainly used in
Radio frequency identification (RFID), printed wiring board (PCB), electronics panel type display, sensor, Electronic Paper, solar cell and thin
The fields such as membrane switch, water-based UV electrically conductive inks represent the development of film printing electronic material, even whole printed electronic industry
Direction, it is expected to turn into the following cutting edge technology for changing human life style.It is applied to the electrically conductive ink of printed electronics industry at present
