On May 9, it was learned from the Xinjiang Institute of Physics and Chemistry of the Chinese Academy of Sciences (hereinafter referred to as "Xinjiang Institute of Physics and Chemistry") that researchers from the institute used glass fiber fabric as raw material to successfully prepare a new material for high-performance electromagnetic interference shielding, providing an important alternative to traditional metal shielding layers. The relevant research results were recently published in the Journal of Materials Science and Engineering B.
With the increasing popularity of various artificial intelligence devices such as smartphones, laptops, wearable technologies, and communication devices, there is an urgent need for high-performance electromagnetic interference shielding materials to meet the challenges of electromagnetic interference and ensure electromagnetic compatibility. Traditional shielding materials and technologies, such as metal shielding layers made of materials such as copper or aluminum plates and metal shells, have limitations such as high density, rigidity, easy corrosion, and low mechanical strength. Conductive fabric materials have become a promising alternative shielding solution due to their inherent flexibility, lightness, and relatively low cost.
Flow chart of the preparation process of GFF materials with chemical copper plating. Recently, researchers from the Xinjiang Institute of Physics and Chemistry achieved high uniformity and high-quality copper nanoparticle deposition on three-dimensional glass fiber fabrics through chemical copper plating, and successfully prepared new materials for high-performance electromagnetic interference shielding. Glass fiber fabric as the substrate has the advantages of high tensile strength, heat resistance, fire resistance, durability and low density.
Researchers found that at the optimal deposition temperature, it can achieve increased copper thickness, improved surface coverage, enhanced crystallinity and interface interaction, which is also the main factor in enhancing the shielding effect of the material.
It is worth noting that the chemical copper plating method used by the research institute provides an efficient and scalable way to produce high-performance electromagnetic interference shielding materials. The resulting copper-plated glass fiber fabric is expected to be widely used in many fields such as electronic products, communication systems, smart textiles, and protective clothing in high-radiation environments.
