碳基材料电磁波吸收性能优化研究进展
Recent progress in increasing the electromagnetic wave absorption of carbon-based materials
摘要
Abstract
High-performance electromagnetic wave absorbing materials(EWAMs)are expected to solve electromagnetic wave radiation problems in both the military and civil fields.The desired features of EWAMs include strong absorption over a broad band-width,low density,thinness,oxidation resistance,wear resistance,ability to withstand high-temperatures and high strength.Carbon-based materials,including nanostructures and composites,are attractive alternatives to EWAMs because of their unique structures and properties.We summarize recent achievements in carbon-based EWAMs,including different dimensional(0D,1D,2D and 3D)carbon nanostructures and various types of carbon composites(dielectric/carbon,magnetic/carbon)and hybrids.The factors affect-ing the absorption of electromagnetic microwaves include electrical conductivity(σ),permittivity(ε)and permeability(μ)are dis-cussed based on the electromagnetic microwave absorption mechanisms.Representative carbon-based EWAMs and the correspond-ing mechanisms of improving their electromagnetic microwave absorption are highlighted and analyzed.Strategies for the modifica-tion of carbon-based EWAMs are summarized and research trends are proposed.关键词
