Abstract

Functional films with electromagnetic interference (EMI) shielding capabilities and pressure sensing functions epitomize the intersection of materials science and electronics. These films not only protect against electromagnetic interference but also provide essential data on mechanical stresses, thus improving the reliability, performance, and safety of electronic devices and structures. Carbon cloth (CC) offer excellent air and moisture permeability, ensuring long-term comfort when in contact with human skin; however, they face challenges in achieving highly effective EMI shielding. In this study, a Cu₃Se₂ coated CC based composite film was fabricated using a facile electrodeposition method. The EMI shielding effectiveness was significantly enhanced from 15 dB to 63 dB, a more than fourfold improvement. The Cu₃Se₂/CC film also demonstrated distinctive resistance variation and high sensitivity when used as pressure sensors to detect human motions, including finger bending, wrist flexion, knee movement, and elbow swing. Additionally, the Cu₃Se₂-modified textile exhibited flame retardancy, excellent flexibility, and breathability. This work highlights the potential for cost-effective, high-EMI-shielding textile sensors and paves the way for the development of multifunctional wearable electronics.

期刊介绍： The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
