Processing of Graphene Oxide for Enhanced Electrical Properties

Prevention of electrostatic discharge is a very important aspect of the electronic domain. The development of electrostatic dissipative (ESD) materials is crucial for packaging materials. The present work focuses on chemical‐free air plasma‐treated graphene oxide (PT GO) loaded polyvinylidene fluoride (PVDF)/polysulfone (PSF) blends for ESD applications. Molecular vibrations and phases of the host polymer system and filler confirmed by Raman spectroscopy were observed. Decreased intensity and interplanar spacing demonstrate exfoliation of GO due to plasma exposure confirmed by X‐ray diffraction (XRD). GO clusters in the host polymer blend system are investigated by scanning electron microscope (SEM). The electrical properties of modified blends are obtained by an impedance analyzer. Enhanced electrical conductivity up to 10−3 (AC) and 10−1 (DC) S cm−1 for plasma‐treated samples demonstrated excellent electronic transportation within the polymer matrix mutually matching the ESD. Reduced area under the curve of impedance confirms the increased electrical conductivity of material due to enhanced conducting boundaries because of plasma exposure. Overall, adequate results of the modified polymer blends by plasma‐treated GO could be emerging material for ESD applications.

Our work investigates the interaction of synthesized graphene with the SARS-CoV-2 virus using molecular docking and molecular dynamics (MD) simulation method. The layer dependent inhibitory effect of graphene nanosheets on spike receptor-binding domain of 6LZG, complexed with host receptor i.e. angiotensin-converting enzyme 2 (ACE2) of SARS-CoV-2 was investigated through computational study. Graphene sample was synthesized using mechanical exfoliation with shear stress and its mechanism of inhibition towards the SARS-CoV-2 virus was explored by molecular docking and molecular dynamics (MD) simulation method. The thermodynamics study for the free binding energy of graphene towards the SARS-CoV-2 virus was analyzed. The binding energy of graphene towards the virus increased with an increasing number of layers. It shows the highest affinity of À17.5 Kcal/mol in molecular docking while DG binding is in the order of À28.01 ± 0.04 5 Kcal/mol for the seven-layers structure. The increase in carbon layers is associated with an increasing number of edge sp 3-type carbon, providing greater curvature, further increase the surface reactivity responsible for high binding efficiency. The MD simulation data reveals the high inhibition efficiency of the synthesized graphene towards SARS-CoV-2 virus which would help to design future in-vitro studies. The graphene system could find potential applications in personal protective equipment and diagnostic kits.
