A Review of Various Synthesis Methods of Graphene and Applications

“…Electron delocalization investigation to be responsible for these polymers' increased electrical conductivity Polymer films were created by mixing an emeraldine base with dodecyl benzene sulfonic acid The electromagnetic and electrical resistance of the films were measured. Polymer films doped with acid, the thickness of which varies from 1 to 30 m [34,35]. The conductivity increased from 10 to 100 Scm -1 as the layer thickness grew.…”

Fabrication of One-Dimensional Polypyrrole Nanochains for a High-Efficiency Electromagnetic Wave Absorber with a Low Filler Loading

“…21 To date, PPy nanomaterials with different morphologies like nanoparticles (NPs), nanorods, nanofibers, etc., have been proven to be effective absorbers. Dai et al 22 fabricated a spectrum of PPy NPs with tunable conductivity and found that PPy with medium conductivity achieved a superior wave attenuation intensity with a minimum reflection loss (RL min ) value of −46.1 dB under a filler amount of 20 wt %. Except for PPy NPs, one-dimensional (1D) hollow PPy nanorods 23 and PPy nanofibers 24 were also exploited as highly efficient EWAMs with lower filler contents due to their structural advantage.…”
