Recent progress in TiO₂-based microwave absorption materials

Abstract

It is particularly important to develop high-performance microwave absorption (MA) materials to answer the increasingly serious electromagnetic pollution. Recently, titanium dioxide-based (TiO2-based) composites have become a research hotspot due to...

Ultraflexible Ultrathin 3D/1D Hierarchical Interpenetrating Ni-MOF/CNT Buckypaper Composites: Microstructures and Microwave Absorption Properties

“…It is critically necessary to develop an effective microwave-absorbing material (MAM) to lessen the threat that electromagnetic pollution poses to military security, communication equipment, and human health. − Carbon nanomaterials are considered potential microwave attenuation materials owing to their high electrical conductivity and low weight. − One-dimensional (1D) carbon nanotubes (CNTs) stand out among carbon nanomaterials because of their capacity to create microcurrent networks by promoting electron transport in response to microwave migration and hopping. − Moreover, 1D CNT possesses significant mechanical strength . Despite these advantages of CNTs, their poor impedance matching due to their unusually high electrical conductivity limits their application in microwave absorption. , Thus, creating nanomaterial architectures and combining different nanomaterials to improve impedance matching are intriguing research avenues.…”
