Another approach to improve the properties of chitosan hydrogels is via the preparation of polymer composites. Porous hydrogels of N-carboxymethyl chitosan/polyvinyl alcohol were prepared by Lee et al. [99]. Hydroxypropyl chitosan was combined with sodium alginate for the formation of biodegradable hydrogels [100]. Chitosan-hyaluronic acid composite was prepared by Tan et al. [101]. [Pg.28]

Similar to the chemical modifications applied to alginate, chitosan can be treated with chloro-acetic acid, ethylene oxide, and propylene oxide to obtain sodium car-boxymethyl chitosan, hydroxyethyl chitosan, and hydroxypropyl chitosan, respectively. These derivatives are highly absorbent and can be used for the production of superabsorbent fibers for medical applications. In addition to enhanced absorption properties, it is known that carboxymethyl chitosan possesses unique wound-healing properties whereby the application of foams, hydrogels, or nonwoven dressings can effectively promote the healing of chronic ulcerative wounds. [Pg.57]
