Non-magnetic bimetallic MOF-derived porous carbon-wrapped TiO2/ZrTiO4 composites are firstly used for efficient electromagnetic wave absorption. The absorption mechanisms including enhanced interfacial polarization and essential conductivity intensively discussed. Modern communication technologies put forward higher requirements (EMW) materials. Metal-organic framework (MOF) derivatives have been widely concerned with its diverse advantages. To break the mindset of magnetic-derivative...
Metal-organic frameworks (MOFs) manifest enormous potential in promoting electromagnetic wave (EMW) absorption thanks to the tailored components, topological structure, and high porosity. Herein, rodlike conductive MOFs (cMOFs) composed of adjustable metal ions Zn, Cu, Co, or Ni ligands hexahydroxytriphenylene (HHTP) are prepared attain tunable dielectric properties for a EMW absorption.

Designing a functional, conductive metal-organic framework (cMOF) is highly desired. Substantial efforts have been dedicated to increasing the intralayer conjugation of cMOFs, while less dedication has made tuning interlayer charge transport nanosheets for controllable dielectric property.
