NEW CHITOSAN STRUCTURES IN THE FORM OF THE THERMOSENSITIVE GELS
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2008, Vol 0, Issue
Abstract
Chitosan hydrogels can be formed at normal body temperature with the use of β-sodium glycerophosphate. An optimum deacetylation degree of chitosan to form a gel is around 80 - 90%. Chitosan solutions with high DD (97%) start gelling already at the temperature below 20 °C. An advantageous ratio of the amount of chitosan to β-disodium glycerophosphate is around 0.3 - 0.45. Thermosensitive gels can be formed from various salts (acetate, lactate).
