“…Polymer nanocomposites are hybrid materials composed of a polymer matrix and nanoscale fillers, which can enhance the properties and functionality of the polymer matrix [1][2][3][4]. It is widely investigated that the surface decoration of these fillers using a variety of materials is a promising strategy to further improve the properties and performance of polymer nanocomposites [5][6][7][8]. The surface decoration involves the modification of the surface chemistry and morphology of the nanofillers to enhance their compatibility with the polymer matrix and improve the interfacial interactions between the two components.…”

Here, we have syntheized Ppy (Polypyrrole) decorated GO (graphene oxide) and investigaed its morphological and optical characteristics. For fabrication of nanocomposites, in-situ polymerization technique was used. The crystalline size and strain of the synthesised sample were determined using an X-ray diffractometer (XRD). The surface morphology of the nanocomposites was investigated using field emission scanning electron microscopy (FESEM). The optical bandgap and PL spectra of the synthesised sample were examined using a photospectrometer and photoluminescence (PL) technique. The calculated crystalline size was ~ found as 5.91 nm with strain ~ 0.33907. In PL spectra, two peaks were found at ~ 430 nm and ~ 500 nm. The direct bandgap was calculated as~ 2.22 eV (visible region). Insights into their structural and optical characteristics are gained from the synthesis and characterization of PPy decorated GO nanocomposites, opening the door for further research and application in a variety of fields.

The mitigation of hazardous effects of chemical dyes on the environment and living organisms, greatly demands an efficient and effective management of dye-laden wastewater. One such solution gaining prominence is the utilization of metal-infused nanofibers-based dye removal techniques, which are simple, effective, and environmentally friendly. In this report, we present the fabrication of mechanically stable hydrophobic nanofibers infused with metal blends, fabricated through the utilization of electrospinning techniques. The successful fabrication of these mechanically stable hydrophobic nanofibers is evidenced through contact angle measurements, tensile tests, and FESEM analysis. While polystyrene-based nanofibrous mats were anticipated to be effective, nanofibrous mats infused with Cu-Fe and Cu-Ni metal blends exhibit exceptional efficacy in degrading dyes. The size and morphology of nanofibers depend on polymer concentration, with the average diameter increasing from 13 to 20%. At a 20% polystyrene concentration, only nanometer-scale fibers of polystyrene polymers were fabricated, while both Cu-Fe and Cu-Ni metal blend-infused fibers were synthesized in micrometers. Fibers infused with Cu-Fe and Cu-Ni metal blend at a 17% polymer concentration displayed nano-scale diameters, confirmed by FESEM characterizations. The heat-based technique is identified as an accessible and cost-effective approach for industries reliant on color-based processes.
