چکیده مقاله:

Natural polysaccharide-based hydrogels show unique properties such as biodegradability, biocompatibility, stimuli-responsive characteristics and biological functions making them a material of option for various applications. Actually, during the last few years, a number of biopolymers-based hydrogels have attracted great interest for different applications such as biomedical area, toxic ion removal and waste-water treatment, agriculture, biosensors, and tissue engineering. In order to improve the drawbacks related to hydrogels, nanocomposite hydrogels were extended by incorporating different types of nanoparticles in the hydrogel network. This research focuses on preparation of biodegradable chemically cross-linked hydrogels hybrid composites consisting of metal oxide nanoparticles (CuO-ZnO), two natural and synthetic polymers including the polysaccharide extracted of quince seed mucilage (QSM) and functionalized poly vinyl alcohol which are both inexpensive, and exhibits remarkable mechanical properties. QSM which is obtained from Cydonia Oblonga has been modified through graft copolymerization and network formation using APVA and acrylic acid (AA) as the monomers, ammonium persulphate (APS) as an initiator, and MBA as a cross-linker. Various reaction parameters such as amount of initiator and solvent, reaction time and temperature, pH, and monomer and cross-linker concentration, were optimized. A range of structural, mechanical and practical techniques were utilized to identify the hydrogels including, FTIR, UV/VIS, XRD, EDAX, TGA and swelling and hydrolytic stability.
