CHARACTERIZATION OF NANOPARTICLES BASED ON GUARGUM SYNTHESIS

Abstract

Because of their distinct chemical and physical characteristics, small silver particles (Ag NPs) as a subject of ongoing research. They are useful for the variety of uses visual, antibacterial, catalytic, and electric capabilities, and they may be made utilising a number of green chemical methods. Guar gum (GG), an organic material that we used an oxidant in our experiment, was used to create silver nanoparticles. A capping agent is another function of guar gum. Using straight forward method of dip and spinning the coating on glass substrates, Ag/GG composite thin films were created. To determine the structural, chemical, and optical characteristics of the materials that were synthesised, various characterization techniques were applied. Particle size was determined by SEM images to be between 100 and 150 nm. Guar gum is present and serves as a capping agent, according to the FTIR analysis. The absorbance peak occurs within the UV-visible spectrum occurs around 450 nm, and the energy of the optical band gap, Eg, is approximately 1.86 eV. The tiny particles have uses in sensors and physical semiconductor.
