▎ 摘　　要

NOVELTY - The method involves using an acidic solution with corrosion, an alkaline solution, an oxidizing solution, acidic-oxide mixed solution or alkaline-oxide mixing solution for hydroxylation treatment to the surface of the insulating substrates, and cleaning and drying. The material to be printed, solvent A is selected, and jet printing ink solution is prepared. One conductive substance in the jet ink solution is selected for electrospray printing, where the heating temperature of the insulation substrate is higher than the boiling point of the solvent A by more than 20?oC in the process of electro-electro-hydrolysis printing. The printed insulated substrate is sintered, solvent A and the solvent B are removed, and the jet print ink solution is cured or converted to obtain a dense functional structure. USE - Method for realizing electro-hydrodynamic spraying printing on insulating substrate used in field of flexible electronics, biomedical and micro-nano optical multifunctional sensor. ADVANTAGE - The method has simple operation, does not need complex electrode structure design, the formed conductive liquid film to the shape feature of the printing material, structure function does not cause interference, effectively solves the problem that the electric spray printing on the insulating substrate cannot be continuously carried out, enlarges the type and range of the controllable printing material and the substrate, improves the printing stability, reliability and continuity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram showing the ceramic sheet by conductive coating solution before after liquid cone state at the nozzle and under 100 times of microscope.
