铝粉涂覆型电磁波响应/红外隐身双功能织物的制备及性能
Preparation and properties of aluminum powder-coated fabrics with dual functions of electromagnetic wave response and infrared stealth
摘要
Abstract
To prepare the dual-functional fabrics with electromagnetic shielding and infrared stealth,aluminum powder was used as a filler,and a composite coating was prepared by combining polyacrylic acid resin.The composite coat-ing was uniformly applied to cotton fabric via a coating method,resulting in a dual-functional coated fabric with high electromagnetic shielding performance and low infrared emissivity.The performances of the fabric were test-ed and compared with other metal-coated fabrics.The results show that compared with fabrics coated with copper powder,bronze powder,and nickel powder,the fabric coated with aluminum powder exhibits superior electro-magnetic shielding performance and infrared stealth performance.With the increase in aluminum powder content and the thickness of the aluminum powder coating,the electromagnetic radiation intensity of the aluminum pow-der-coated fabric first decreases gradually and then tends to stabilize.The optimal preparation conditions are as follows:aluminum powder with a particle size of 200 mesh and a mass fraction of 20%,and a coating thickness of 0.2 mm.Compared with the uncoated fabrics,the aluminum powder-coated fabric prepared under these con-ditions exhibits a 24%reduction in electromagnetic radiation intensity,a 22%decrease in infrared emissivity,and a 21%increase in near-infrared reflectance within the wavelength range of 780-2 500 nm.Thus,it pos-sesses the dual functions of infrared stealth and electromagnetic wave shielding.关键词
