Ordered Mesoporous Multishell Composite Microspheres with Controlled Loading of Magnetic Particles for Enhanced Electromagnetic Wave Absorption Performance

Industrial & Engineering Chemistry Research, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 9, 2025

Precise construction of rational structures and optimization material components are the main strategies for design preparation novel high-performance electromagnetic wave (EMW) absorbers. Here, SiO2/RF@m-PDA multishell composite microspheres with an ordered mesoporous structure produced by a two-step reaction simultaneous hydrolysis precipitation polymerization dopamine self-polymerization soft stencil method. The monodisperse average particle size 380 nm. Then magnetic Co nanoparticles embedded inside pores using impregnation reduction method, which allows SiO2/C/NC-Co EMW absorbers different component loadings. effective absorption bandwidth SiO2/C/NC-Co-2 reaches 7.36 GHz at thickness 2.2 mm, minimum reflection loss −46.59 dB adjusting filling load absorber. excellent absorbing performance is attributed to dual mechanism synergistic effect magnetic/dielectric abundant heterogeneous interfaces given layer structure. This study provides feasible method prepare complex multicomponent doped
