Abstract: A composite material for electromagnetic interference shielding is provided. The composite material comprises an electrically conductive microscale films based on Transition Metal Carbo-Chalcogenides (Nb2S2C) stack layers. The stack is effective to provide a substantial electromagnetic interference (EMI) shielding. Once decorated with special metallic nanoparticles made mainly with noble metals including Au, Ag and Pd, this efficiency against the EMI is even enhanced. The disclosed technology introduces a special coating that can be applied to electronic devices and materials. This coating acts as a shield that protects these devices from different types of interference that can disrupt their signals and performance. This coating can work on devices that bend or move, and effectively blocks interference across a wide range of frequencies. As such, the disclosed technology keeps devices working smoothly even in places with a lot of electronic “noise” without restricting their flexibility or range of use.
