Abstract
The invention belongs to the technical field of advanced manufacturing and provides a liquid electrode device for coaxial electrospray printing. The liquid electrode device is placed directly under acoaxial nozzle and mainly comprises a displacement table, a cantilever bracket, an electrode liquid storage chamber, a metal plate, a heating sheet, a wire and an electrode solvent. Before printing, the appropriate amount of the electrode solvent is added to the electrode liquid storage chamber, a thin electrode liquid film is formed on an upper surface of the metal plate, and the heating piece atthe bottom of the electrode liquid storage chamber heats the electrode solvent to a certain temperature. In the printing process, an electric field is formed between a coaxial nozzle and the metal plate, the coaxial jet flow firstly contacts the electrode liquid film before reaching the metal plate, a jet flow material dissolves rapidly and spreads, a problem of residual charges due to material accumulation is avoided, jet flow whipping caused by Coulomb repulsive force is eliminated, and printing process stability and printing structure consistency are improved.
Description
technical field [0001] The invention belongs to the field of advanced manufacturing technology, and relates to coaxial electrospray printing integrated platform equipment, in particular to a liquid electrode device for coaxial electrospray printing. Background technique [0002] The electrojet printing technology based on the electrohydrodynamic effect is a method of directly realizing the micro-nano structure on the substrate by using the effect of the local energy field. Highlighting the potential and advantages has become a research hotspot in the manufacture of high-resolution structures in recent years. Electrospray printing has two modes: single cone-jet and coaxial cone-jet. In the coaxial electrojet printing mode, two incompatible materials form a stable coaxial cone-jet at the outlet of the coaxial nozzle under the joint action of electric field force, mechanical force, surface tension, viscous force, and internal pressure. In this mode, the electric field force a...
