چکیده انگلیسی
Electromagnetic radiation pollution has become a serious threat to human health. Wearable materials with high electromagnetic interference (EMI) shielding are highly desirable to protect people far from electromagnetic radiation. In this study, we prepared flexible and wearable materials with ultrahigh EMI shielding via a facile wet electroless deposition of Ag on surface of cotton fibers (Ag@CFs) in non-woven fabrics. High conductivity of â¼3333 S/m and excellent EMI shielding effectiveness (SE) of â¼71â¯dB were achieved by only costing the wet deposition time of 10â¯s with 1.61â¯vol% Ag coating layers, which was far more than the requirement for common commercial EMI SE of 30â¯dB. The EMI SE of the materials could reach â¼111â¯dB when the Ag plating time was 3â¯min. The ultrahigh EMI shielding performance was ascribed to cell-like configuration, which is the abundant interfaces and porous structure in the Ag@CFs non-woven fabrics, and the voids in Ag layers. The electromagnetic radiation, which was reflected at the interfaces and then absorbed in the composites, was hard to escape from the cell-like configurations. Moreover, the prepared Ag@CFs films could also maintain high EMI SE by suffering dozens of washing times or one thousands of bending times. For example, there were only reduction of a few dB in the EMI SE for the non-woven fabrics with the coating time of 3â¯min after washing 20 times or bending 1000 times. Therefore, this work gave a new strategy for fabricating wearable materials with high-performance EMI shielding.
