The article focuses on the suitability of electrically characterized polypyrrole-banana carbon (PPy-BC) nanocomposites for broadband electromagnetic interference (EMI) shielding application. The environmental-friendly polypyrrole (PPy)-banana carbon (BC) nanocomposites were synthesized via in situ chemical polymerization technique and were characterized using powder X-ray diffraction, FT-IR spectroscopy, scanning electron microscopy (SEM), and UV-Vis spectroscopy techniques. Frequency-dependent dielectric, impedance, loss tangent, and conductivity measurements were analyzed in detail in the frequency range of 20 Hz to 1 MHz. The EMI shielding efficiency (SE) of PPy-BC nanocomposites were performed in the broad frequency range of 12 GHz to 18 GHz (Ku band), relevant for practical applications. The EMI SE achieved for PPy-BC nanocomposites was in the range of * 12 to * 18 dB. The present investigation also explores the anticorrosion property of polypyrrole nanocomposites coatings on mild steel surface in 5 M hydrochloric acid solution through atomic absorption spectroscopy (AAS), potentiodynamic polarization, Nyquist plots, and SEM techniques. AAS studies revealed that corrosion inhibition efficiency increases with an increase in the concentration of polypyrrole nanocomposites. Electrochemical impedance measurements showed that charge transfer resistance values depend on the composites concentration. Obtained SEM results also support the AAS and electrochemical results. The observed electrical property and EMI shielding properties with anticorrosive behavior suggest that PPy-BC nanocomposites can be optimized for useful technological applications.

The stoichiometric ratio 2:1 mix of 1-phenylpiperazine and oxalic acid dihydrate followed by slow evaporation results ina new material, bis(4-phenylpiperazin-1-ium) oxalate dihydrate, with the general chemical formula (C10H15N2)2(C2O4).2H2O, indicated by PPOXH. The title compound’s asymmetric unit and three-dimensional network have been determined by single crystal X-ray diffraction. Intermolecular O-H…O, N-H...O and C-H...O hydrogen bonding assist in maintaining and stabilization of the crystal structure of this new compound. Hirshfeld surface analysis and two-dimensional fingerprints have been performed to quantify the non-covalent interactions in the PPOXH structure. The vibrational modes of the different characteristic groups of the title chemical were identified using infrared spectrum analysis. The thermal characterization of this product was studied by a coupled TG/DTA analysis. The ultraviolet-visible absorption spectrum has been used to study the optical properties and the energy gap of this compound. DFT calculations were employed to evaluate the composition and properties of PPOXH. The analysis of HOMO-LUMO frontier orbitals analysis allows us to understand the chemical reactivity of this supramolecular compound and to determine the electrophilic and nucleophilic sites responsible for electron transfer. Topological analysis (AIM), reduced density gradient (RDG), molecular electrostatic potential surface (MEPS) and Mulliken population were analyzed to evaluate the types of non-covalent interactions, localization of electrons in space, atomic charges and molecular polarity in depth.
