Abstract
The objective of study is preparing multi-responsive, nontoxic, and highly stable nanocomposite hydrogels for effective reduction and decolonization of broad spectrum of toxic dyes. The nanocomposite hydrogels are composed of N-isopropy acrylamide, acrylic acid, and silver/chitosan nano-dispersion and prepared by the effect of Gamma radiation at a dose rate of 2.6 kGy/h. The physical and chemical properties of the various prepared nanocomposites hydrogels were studied by various techniques as SEM, TEM, XRD, and FTIR. The swelling properties of the nanocomposites hydrogels were studied under various conditions as pH and temperature. Given the physical properties of multifunctional thermo-responsive N-isopropy acrylamide, acrylic acid hydrogel, and its Ag nanocomposite, they hold the strong potential for toxic dyes degradation as Erioglaucine as a model dye. In this paper, we review various silver and thermo-responsive poly (N- isopropylacrylamide/Acrylicacid /silver), (PNIPAM/AA/Ag) nanocomposites and highlight their high activity as a catalyst for degradation of various types of dyes.
