Biomedical Textiles Through Multifunctioalization of Cotton Fabrics Using Innovative Methoxypolyethylene Glycol-N-Chitosan Graft Copolymer
Original language description
Multifunctioalization of cotton fabrics was developed by a novel finishing formulation. The method is based on chitosan-N-polyethylene glycol graft kopolymer along with citric acid and sodium hypophosphite (SHP) as catalysts. Treatment of the cotton fabric resulted in the chemical attachment of the copolymer to the cotton fabric via bridging-based esterification where the latter involves reaction of one molecule of the polycarboxylic acid (citric acid) with both the amino group of the copolymer and thehydroxyl groups of cotton. Inclusion of the copolymer in the crosslinked structure of cotton as well as by hydrogen bonding and van der Waals forces are additionally possible. Synthesis of the copolymer was raised out by the reaction of chitosan with methoxy polyethylene glycol (MPEG) aldehyde followed by the reduction with sodium borohydride. MPEG was prepared by oxidation of PEG with acetic anhydride in dimethyl sulphoxide at room temperature.
