“…The miscibility of materials in polymer blends is dependent on specific interactions between the components such as: the degree of hydrogen bonding, ionic and dipole, p-electron and chargetransfer complexes. From the literature, there is evidence of inter-and intramolecular hydrogen bonding and/or ionic interactions between chitosan and the following homopolymers: silk fibroin, 15 poly(acrylic acid), 16 poly(3-hydroxybutyric acid), 17 poly(ethylene glycol), 18 poly(vinyl pyrrolidone), 19 nylon-4, 20 pectin, 21 poly(caprolactone), 22 poly(vinyl alcohol), 23 and collagen. 24 Chitosan has also been reported to be immiscible with poly(lactic acid), 25 nylon-6, 20 and cellulose.…”
