Carbon nanotube-based nanocomposites are being increasingly utilized in materials for electromagnetic shielding purposes due to their exceptional electrical and mechanical properties. The current study optimizes a simple procedure prepare multi-wall carbon nanotubes (MWCNTs)-based hydrogel out of water, gelatin, glycerol. content ratio each component the composite is carefully selected optimize dielectric properties over (EM) wave frequency 0.5 20 GHz. were prepared with MWCNT concentrations ranging from 0.1 0.9 wt%. dispersion MWCNTs was investigated confirmed using scanning electron microscope (SEM). parameters, including real constant ε′, imaginary ε″, tangent loss tan δ along DC AC conductivity (σDC,σAC) investigated. shows significant enhancement parameters as concentration increased. effectiveness (SE) against waves range 1.7 6.0 GHz found be enhanced have ranges 10 dB 26 dB, equivalent 90% more than 99% incident radiation, respectively.
