Morphological characterization and impedance spectroscopy study of porous 3D carbons

What is it about?

we used a microwave method to produce porous carbonaceous materials designated as graphene foam/polyvinyl alcohol/formaldehyde and graphene foam-polyvinyl alcohol/phenol-formaldehyde from graphene foam, phenol formaldehyde and polyvinyl alcohol (PVA). Scanning electron microscopy (SEM), Raman spectroscopy and Fourier-Transform Infrared Spectroscopy (FTIR) were used to characterize the surface morphology, structural defects and functional groups of the materials respective

Why is it important?

The physicochemical properties of the electrolyte ion (di ff usion) and its in fl uence on the capacitive behavior of the porous materials were elucidated. These encouraging results demonstrate the versatile potential of these porous materials (GF/PVA/F and GF/PVA/PF) in developing high energy storage devices.
