“…The carboxylation reaction by oxygen is disregarded for some reasons: (1) low reaction temperature (À5-0°C) in the absence of air (oxygen), (2) no color change due to oxidation, (3) absence of characteristic asymmetric and symmetric carbonyl stretching bands (both strong at 1600 and 1430 cm À1 , respectively). 17 As for carbonation, some FTIR analyses have been reported related to the characteristic peaks of the carbonate ion. The characteristic peaks at 1673, 1350, and 1305 cm À1 are reported for sodium hydrogencarbonate ion.…”

In recent years, intelligent hydrogels which can change their swelling behavior and other properties in response to environmental stimuli such as temperature, pH, solvent composition and electric fields, have attracted great interest. The hydrogels based on polysaccharides incorporated with thermo-responsive polymers have shown unique properties such as biocompatibility, biodegradability, and biological functions in addition to the stimuli-responsive characters. These "smart" hydrogels exhibit single or multiple stimuli-responsive characters which could be used in biomedical applications, including controlled drug delivery, bioengineering or tissue engineering. This review focuses on the recent developments and future trends dealing with stimuli-responsive hydrogels based on grafting/blending of polysaccharides such as chitosan, alginate, cellulose, dextran and their derivatives with thermo-sensitive polymers. This review also screens the current applications of these hydrogels in the fields of drug delivery, tissue engineering and wound healing.

“…It is worth to remark that CMC used in this work was as sodium salt. The assignments are according with reports of IR spectroscopy studies of CMC (Bono et al 2009, Heydarzadeh et al 2009, Vasile et al 2004. Before, the main assignments for PHEMA were disscused.…”

“…This spectroscopy may used to identify the composition of polymers, to monitor polymerization processes, to characterize polymer structure, to examine polymer surface, and to investigate polymer degradation processes. There are several reports of use of IR spectroscopy to evaluate grafting of acrylic monomers onto natural materials as carboxymethyl cellulose (CMC) and chicken feathers (CF) (Martínez et al, 2003, Vasile et al, 2004, Zohuriann-Mehr et al, 2005, Joshi and Sinha, 2006.…”
