Preparation of Arylidene Sulfacetamide Reduced Graphene Oxide Nanocomposites and Measure some of its Optical Properties

Nanocomposites based on Schiff base reactions with reduced graphene oxide were prepared, and their optical and mechanical properties were studied. The preparation methods included synthesizing Schiff bases using sulfacetamide and aromatic benzaldehydes, preparing graphene oxide via the modified Hummer's method, and reducing it with aqueous hydrazine. Infrared spectroscopy (FTIR) and (NMR) analyses confirmed the successful formation of the nanocomposites. The results revealed that the prepared composites exhibit unique properties, with optical transmittance increasing variably between 49% and 89%, and energy band gaps ranging from 3.5 to 4.0 eV. Scanning Electron Microscope (SEM) images demonstrated that these composites possess distinctive nanostructures, enhancing their hydrogen bonding capability and increasing their effective surface area. These properties make the composites suitable for diverse applications in optical, magnetic, and mechanical fields.
