Chitosan (CHI) and chitosan/poly(2-ethyl-2-oxazoline) (CHI/POZ)-based films were prepared\nby casting from aqueous solutions of polymer blends with different compositions. Ciprofloxacin was\nused as a model drug in these formulations. The weight, thickness, folding endurance and transparency\nof blend films were measured and characterised. All films had a uniform thickness (0.06................
