Water-based formulations are preferred for membrane coat application because they do not require the use of noxious solvents. A novel aqueous chitosan-alginate-CaCl(2) system was evaluated as a potential formulation to produce water-insoluble membranes of biodegradable polymers. Chitosan-alginate coacervates were prepared by controlled reaction of chitosan (0.25% w/v) and sodium alginate (0.25% w/v) solutions. Coherent membranes were obtained by casting and drying the coacervates suspended in… CONTINUE READING
