Abstract: In order to solve the challenging problem of large-area high-performance low-frequency transparent electromagnetic shielding glass that is difficult to be manufactured in batch at low cost, a new additive manufacturing method based on electric field-driven micro-jet and electroplating composite is proposed for the preparation of silver-nickel composite metal mesh low-frequency transparent electromagnetic shielding glass, and the basic principle and process flow of preparing silver-nickel composite metal mesh are described; the influence of the main process parameters (printing voltage, printing speed, printing air pressure, printing height, current density, plating time) on the electrical and optical properties of the prepared silver-nickel composite metal grids was revealed through experiments; and with the optimized process parameters, the silver-nickel composite metal grid transparent electromagnetic shielding glass with 10 μm line width, 0.76 Ω/sq square resistance, 90.2 % grid transmittance, and shielding efficiency greater than 40 dB in the low frequency band (10 kHz-30 MHz) has been prepared, and the adhesion between the composite metal grid and the substrate is 5B. It provides a new solution for the mass production of high performance low frequency transparent electromagnetic shielding glass.

Key words: transparent electromagnetic shielding, micro and nano 3D printing, composite metal grids, electric field driven jetting, micro plating
