Chitosan-day nanocomposites

Xu, Y. and Hanna, M.A.Chitosan/day nanocomposite films preparation and characterization Abstract in 2005 IFT Annual Meeting July 15-20, New Orleans, Louisiana. 

Chitosan/day nanocomposites represent an innovative and promising class of materials. Potential biomedical applications of chitosan/clay nanocomposites include the intercalation of cationic chitosan in the expandable aluminosilicate structure of the clay is expected to affect the binding of cationic drugs by anionic clay the solubility of chitosan at the low pH of gastric fluid may decrease the premature release of drugs in the gastric environment ... 

However, there are few reports on chitosan/bentonite nanocomposites (Yang Chen, 2007 Zhang et al., 2009 Wan Ngah et al., 2010). The physical properties and biological response of chitosan strongly depend on the starting materials and nanocomposite preparation conditions. In the present study chitosan/day nanocomposites were prepared using two kinds of clay and different chitosan/day ratios, to evaluate how these variables affect the dispersion of clay particles into the chitosan matrix. The samples obtained were characterized by infrared spectroscopy, x-ray diffraction, and mechanical (tensile) properties.
