Abstract

The invention provides a piezoelectric ceramic ultra-high filling silicone rubber composite ink material for ink direct writing printing and its preparation method and application. The raw materials of the composite ink material mainly include silicone rubber resin, piezoelectric ceramic filler and solvent components , wherein the amount of piezoelectric ceramic filler can reach 90wt%. Its preparation method is to fully disperse the piezoelectric ceramic filler in a solvent, then add silicone rubber resin to fully mix, and finally get it through thickening treatment, which can be directly applied to ink Direct write 3D printing. After testing, the composite ink material has good printing ability, good dispersion and strong supporting force, and the printed piezoelectric parts have good flexibility and piezoelectric output.
