Abstract:A layer−layer composite impedance-gradient structure can achieve good impedance matching characteristics. However, its impedance step and poor bonding fastness between layers are not conducive to the maximization of electromagnetic wave absorption. Based on the concentration-diffusion mechanism of interfacial freezing of conductive polymers, combined with the high conductivity of MXene nanosheets, a fabric structure with a continuous impedance gradient along the thickness direction was creatively constructed. … Show more
