AI Technical Summary
When existing single-dimensional carbon materials are mixed with magnetic nanoparticles, uneven distribution can easily occur, leading to unstable microwave absorption performance of the composite material.
By in-situ growing bimetallic LDH on melamine foam and calcining it at high temperature, a multi-dimensional, multi-component composite material of LDH-derived 2D carbon nanosheets, 0D magnetic nanoparticles and 3D carbon networks is formed, which synergistically improves dielectric loss, magnetic loss and polarization loss.
The prepared multidimensional, multi-component radar absorbing material has excellent microwave absorption capability, improves electron transmission rate and electromagnetic wave dissipation, and provides a new structural design idea for high-performance microwave absorbing materials.
