Study on Preparation of Chitosan Fiber Grafted with β-Cyclodextrin

Abstract:

The aim of the study was to investigate the grafting process of β-cyclodextrin onto chitosan fibers via epichlorohydrin as a crosslinking agent. The parameters influencing the efficiency of the grafting reaction were studied by L9 (34) orthogonal test. The amounts of β-cyclodextrin grafting onto the treated fibers were estimated in terms of levofloxacin content. The optimum process was found to be epichlorohydrin 0.64 ml, temperature25°C, post-reaction time 48h, pre-reaction time 4.5h when chitosan fibers were 0.48g. In the case, the inclusion amount of levofloxacin was 1.792mg/g, and the releasing amount was 0.845mg/g at 35°C. The modified and unmodified fibers were characterized by FTIR Spectroscopy , which indicated that β-CD grafted with chitosan fibers were prepared successfully.
