Research Progress on Anticorrosive Microwave Absorbers
摘要
Abstract
Microwave absorbers are the core components of radar absorbing coatings,and researchers continuously optimize their composition,structure,and preparation processes to achieve'thin,light,wide,and strong'properties.In addition to absorption property,environmental stability is also an aspect that researchers are focusing on.Coatings prepared by magnetic absorbers are prone to oxygen corrosion in marine environments,which will lead to the deterioration of the microwave absorption property and further decrease in the stealth performance of equipment.Therefore,the development of dual-functional absorbers with excellent microwave absorption and anti-corrosion effects is of great significance for improving the long-term service capability of equipment in corrosive environments and reducing the daily maintenance cost. This work focuses on the research progress of preparation ideas and methods for anticorrosive absorbers,mainly including surface modification of magnetic absorbers,surface coating of magnetic absorbers(carbon coating,inorganic oxide coating,organic polymer coating,multi-layer composite coating,etc.),porous structure embedded with corrosion inhibitor,multi-component composites,and new anticorrosive absorbers.The microwave absorption property,corrosion resistance,anti-corrosion mechanism,technical advantages and disadvantages of different types of absorbers are summarized.Surface modification of magnetic absorbers by physical and chemical methods or silane coupling agents is a simple and effective strategy.The preparation process is relatively simple and easy to mass produce,but the long-term corrosion resistance needs to be further improved.Covering the surface of traditional magnetic absorbers with a corrosion-resistant layer is currently the main strategy,which is usually designed as a core-shell structure with single-layer or multi-layer composite coatings.The corrosion-resistant shell can effectively prevent the erosion of corrosive media,but it will also increase the thickness and weight,and may lead to the loss of magnetism.Another important direction in current research is to combine magnetic loss absorbers with corrosion-resistant electrical loss absorbers and polymers.The electrical loss components used include carbon nanotubes,graphene oxide,reduced graphene oxide,conductive polymers,etc.Polyaniline is widely used due to its dual properties of dielectric loss and corrosion resistance.Multi-component composite method usually involves multiple preparation steps,which have shortcomings such as complex preparation processes and difficult stability control. In recent years,with the progress of material science and technology,some new materials have been gradually applied in the field of anti-corrosion and microwave absorption,such as layered double hydroxide(LDH),biomass-derived carbon(BDC),graphene foam,super-helical chiral polypyrrole,metal organic framework(MOF),MXenes,etc.By optimizing the combination of different components,researchers have prepared a series of new microwave absorbers that can realize both microwave absorption and corrosion resistance.However,the current work is still mainly laboratory exploratory research and has not yet formed large-scale manufacturing production. In addition,this work outlines the commonly used testing and evaluation methods for the absorption and corrosion resistance properties of anticorrosive radar absorbers,including coaxial ring method,arc method,electrochemical method,etc.Lastly,the future development directions of anticorrosive radar absorbers are discussed,which primarily involve improving comprehensive performance,optimizing preparation processes,and strengthening assessment and verification,aiming to provide a reference for the research and engineering applications of absorbers.关键词
