Three-dimensional carbon nanotube/SiC nanowire composite network structure for high-efficiency electromagnetic wave absorption
Source abstract
Abstract
Abstract Lightweight high-performance electromagnetic wave absorbing materials have attracted enormous interest. In this work, high-conductivity carbon nanotubes with semiconducting SiC nanowires were combined to construct a three-dimensional composite material for electromagnetic wave absorption. These two kinds of one-dimensional nanomaterials can form a composite electrical conduction network in the matrix, thereby enhancing electrical conductivity and conduction loss. Based on this, the electromagnetic wave absorption properties of the composite materials were further optimized by regulating the ratio between carbon nanotubes and SiC nanowires. When the weight ratio of carbon nanotubes, SiC nanowires and paraffin was 1:29:70, the composite had the lowest −10 dB bandwidth at 3.4 GHz (frequency range between 8.5 and 11.9 GHz) and a minimum reflection loss of −33.77 dB at 10.01 GHz.
