Abstract:Water-soluble coupling reagent N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS) were used to graft 3-aminophenylboronic acid onto carnauba wax latex microspheres for obtaining microspheres with phenylboronic acid functional groups (CW-ABBA). According to the mechanism of controllable interaction between boric acid and 1,2/1,3- polyol, the controllable adsorption of modified carnauba wax latex microspheres on the surface of cellulose membrane was achieved, meanwhile, the treated cellulose membrane materials acquired significant improved physical properties. The results show that at pH of 10.5, the water-vapor transmission rate of modified cellulose membrane is reduced 24.2%, the water repellency, tensile strength and elongation at break are improved 60.2%, 61.9% and 40%, respectively. Hence, the method mentioned above has a potential application value in improvement of the physical properties of fiber products.
