Thermosensitive chitosan gels containing calcium glycerophosphate
2018
Abstract In this paper the properties of thermosensitive chitosan hydrogels, formulated with chitosan chloride with β-glycerophosphate disodium salt hydrate and chitosan chloride with β-glycerophosphate disodium salt hydrate enriched with calcium glycerophosphate, are presented. The study focused on the determination of the hydrogel structure after conditioning in water. The structure of the gels was investigated by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The crystallinity of the gel structure was determined by X-ray diffraction analysis (XRD) and the thermal effects were determined based on DSC thermograms.
