Electric Field Driven Hybrid Micro and Nano 3D Printing of Low Frequency Transparent Electromagnetic Shielding Glass
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.
