Abstract: A method for making an electromagnetic wave shielding material comprises the steps of (a) mixing ternary Fe—Al—Si alloy powders and a solvent to prepare a Fe—Al—Si solution; (b) adding an acid in the Fe—Al—Si solution to release Fe ions through a dissolution reaction; (c) adding copper chloride powders in the Fe—Al—Si solution; (d) adding a lye in the Fe—Al—Si solution to induce a displacement reaction; (e) adding a silane coupling agent in the Fe—Al—Si solution; (f) placing the Fe—Al—Si solution in a microwave reactor to accelerate the displacement reaction; (g) producing a quaternary Cu—Fe—Al—Si alloy after the displacement reaction of the Fe—Al—Si solution, thereby forming a quaternary Cu—Fe—Al—Si alloy solution, which proceeding with a solid-liquid separation and a drying treatment to obtain an electromagnetic wave shielding material composed of quaternary Cu—Fe—Al—Si alloy in solid powders.
