The gelation behavior of chitosan in an alkali/urea aqueous solution was studied by means of rheology, X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The sol-gel transition temperature of the chitosan alkaline solution strongly depends on chitosan concentration and...
