The development of practical and efficient electromagnetic wave (EMW) absorbing materials is a challenging research problem. A mussel-inspired molecular structure regulation strategy using polydopamine to increase the roughness functional groups basalt fiber (BF) surface, which can improve interfacial adhesion. Herein, novel BF-Fe3O4/CNTs heterostructure synthesized through dip-coating adsorption process. three-dimensional network Fe3O4/CNTs hybridin situanchored on surface BF, endows...
ABSTRACTABSTRACTBasalt fibers (BF)-reinforced double-layered resin composite with excellent absorption performance in X band (8.2–12.4 GHz) has been designed, choosing carbon black (CB) and nano-Fe3O4 as absorbent for absorbing layer matching layer, respectively. The electromagnetic parameters of the composites were measured by vector network analyzer using waveguide method. calculated result suggests that an increased amount could significantly improve microwave absorbability single-layered...
The microstructure, pore structure and changes in electromagnetic parameters of cement paste prepared with nano carbon black (CB) were analysed. results showed that the addition CB significantly influenced paste, increasing content pores less than 100 nm improving overall structure. use dispersant further enhanced dispersion increased its filling effect. also had a significant impact on compressive strength presence certain agglomerates reducing strength. However, when (CBC) was 0.5 wt%,...
Abstract: Due to the complexity of design multilayer electromagnetic (EM) wave absorbing materials, it is difficult establish relationship between material parameters (type and filling ratios) EM properties using traditional trial error methods. Based on measured within a few materials Boltzmann mixing theory, database was thereafter built up. In this study, genetic algorithm (GA) used wave-absorbing cement mortar. order verify method, mortar fabricated measured. The simulated results are...
