“…Some of those materials are based on acrylic monomers [ 156 , 157 , 158 , 159 , 160 ] and display important flocculation properties. There are also reports of radiation-induced chitosan grafted with poly(maleic acid) showing high sorption capacity of Co(II) [ 161 , 162 ]. On the other hand, Burillo et al have developed thermosensitive graft copolymers based on chitosan derivatives by gamma radiation [ 163 , 164 , 165 , 166 ].…”

The functionalization of polymeric substances is of great interest for the development of innovative materials for advanced applications. For many decades, the functionalization of chitosan has been a convenient way to improve its properties with the aim of preparing new materials with specialized characteristics. In the present review, we summarize the latest methods for the modification and derivatization of chitin and chitosan under experimental conditions, which allow a control over the macromolecular architecture. This is because an understanding of the interdependence between chemical structure and properties is an important condition for proposing innovative materials. New advances in methods and strategies of functionalization such as the click chemistry approach, grafting onto copolymerization, coupling with cyclodextrins, and reactions in ionic liquids are discussed.

“…This has also been discussed previously by others. 39 Aer further purging with N 2 for 2 h, the graing mixture containing the lms was heated to 55 C for 16 h. Aer graing, the resulting membranes (designated L-poly(VBC)) were thoroughly washed in toluene, heated in toluene for 70 C for at least 4 h, dried in a vacuum oven at 50 C for no less than 3 h, and weighed. The degree of graing (DoG, a standard measure of graing yield) 40,41 were calculated using eqn (1) to be 121%:…”

“…Graft polymerization of vinyl monomers onto chitosan using gamma irradiation have been reported [30] for examples butyl acrylate onto chitosan [31], it was revealed that grafting percentage increased as the monomer concentration and the total irradiation dose were increased. Radiation grafting of acrylamide and maleic acid on chitosan and its effective application for removal of Co(II) from aqueous solutions has been studied by Saleh et al; [32] it was found that chitosan-P(acrylamide) and chitosan-P(maleic acid) show high sorption capacity toward Co(II) as. 150 mg/g and 421 mg/g, respectively, that makes them potential sorbents of Co(II) for wastewater treatment.…”

Nanocomposite hydrogels were synthesized by γ-radiation-induced copolymerization and crosslinking of Chitosan biopolymer (CS), acrylic acid (AAc) and TiO 2 nanoparticles (CS-PAAc/TiO 2). The structure, morphology, and properties of the nanocomposites were investigated using Fourier-transform infrared spectroscopy, X-Ray Diffraction, Scanning electron microscopy, Transmission electron microscopy, and thermogravimetric analysis techniques. The nanocomposites hydrogel was used for the removal of methylene blue dye (MB) from wastewater. It was found that the presence of TiO 2 in the copolymeric matrix enhances the adsorption by increasing the physical interaction between the dye molecules and the adsorbent surface. The removal percentage increases with the increase in pH of the medium of all investigated samples and the maximum value is obtained at the solution pH is 10. The maximum adsorbent dosage for CS-PAAc/ TiO 2 nanocomposites is 0.20 g and for CS-PAAc hydrogel is 0.15 g per liter of the adsorbate. This study revealed that the loading of TiO 2 nanoparticles into the polymeric matrix of CS-PAAc does a remarkable increase in the removal parentage of MB dye from its aqueous solution.
