Synthesis of Ultralight and Porous Magnetic g-C3N4/g-Carbon Foams with Excellent Electromagnetic Wave (EMW) Absorption Performance and Their Application as a Reinforcing Agent for 3D Printing EMW Absorbers

Herein, magnetic g-C3N4/g-carbon foams (CNFs) are fabricated via impregnating the as-prepared melamine–formaldehyde (MF) foams in iron acetylacetone (Fe(acac)3) N,N-dimethylformamide (DMF) solution...
