Abstract
In recent years, nanocomposites have been the main point of study in the field of nanotechnology. In this field, the development of safe and eco-friendly techniques for the preparation of nanocomposites is critical. Nanomaterials can be prepared by several methods including chemical, physical, and biological methods. The chemical method contains many techniques (laser ablation, laser irradiation, lithography, cryochemical synthesis, sono-decomposition, thermal decomposition, electrochemical reduction, and chemical reduction). Various biological systems including plant extracts, small biomolecules, bacteria, and fungi have provided alternative safer methods to chemical methods. Chemical reduction is the most popular approach for the preparation of silver nanoparticles. Characterization of polymer/silver nanocomposites is important to evaluate the functional aspects of the prepared particles. The silver nanoparticles encapsulated within polymer chains were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS) in addition to transmission electron microscopy (TEM) and thermal gravimetric analysis (TGA). There are several mechanisms available to convert silver ions to metallic silver.
