摘要
为解决大面积高性能低频透明电磁屏蔽玻璃难以低成本批量化制造的挑战性问题,提出一种基于电场驱动微喷射和电镀的复合增材制造新方法,用于制备银镍复合金属网栅低频透明电磁屏蔽玻璃,阐述了制备银镍复合金属网栅的基本原理和工艺流程;通过实验揭示了主要工艺参数(打印电压、打印速度、打印气压、打印高度、电流密度、电镀时间)对制备银镍复合金属网栅电学性能、光学性能的影响规律;并结合优化的工艺参数,制备了线宽10 μm、方阻0.76 Ω/sq、网栅透过率90.2%、在低频波段(10 kHz~30 MHz)屏蔽效能大于40 dB的银镍复合金属网栅透明电磁屏蔽玻璃,复合金属网栅与衬底的黏附力为5B,实现了高屏蔽效能和高透过率电磁屏蔽金属网栅的制造,为高性能低频透明电磁屏蔽玻璃的批量化制造提供了全新的解决方案.
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.
