▎ 摘　　要

NOVELTY - Preparing ultrafine grid transparent electrode with high-aspect-ratio comprises printing single layer of grid with ultrafine line width by combining electric field driven jetting three-dimensional printing and charge-induced self-alignment, and then using charge-induced self-alignment to print many layers of ultrafine grid, connecting conductive nozzle to alternating-current pulse power supply, setting distance between nozzle and insulating substrate, forming electric field between nozzle and substrate, generating cone jet flow at tip of nozzle under action of electric field to be deposited on substrate to form printing material micro-droplet and moving nozzle upwards, continuing to control, and accumulating charged printing material micro-droplets on formed layer with charge-induced self-alignment under action of electric field between formed layer and nozzle until the grids with set number of layers are printed, and sintering grid printed part to prepare grid transparent electrode. USE - The method is useful for preparing ultrafine grid transparent electrode with high-aspect-ratio. ADVANTAGE - The method: provides ultrafine grid transparent electrode with a high-aspect-ratio that has a wide selectable range for a substrate material, and has high conductivity and high light transmittance, thus achieving desirable popularization and application values; and improves stability of the electric field.
