摘要
Abstract
Sodium alginate/sodium carboxymethyl cellulose were used as the raw material and the aqueous solution of calcium chloride and ethanol co-solvent were used as mixed coagulation bath.The sodium algihate/sodium carboxymethyl cellulose blended films were prepared by changing the ratio of ethanol in coagulation bath.The tensile strength,elongation at break,water absorption,water retention and water vapor transmission of the blended films with different amounts of ethanol were measured.The structure was characterized by infrared spectroscopy (IR),scanning electron microscopy (SEM) and X-ray diffraction (XRD).The results showed that the compatibility of blended films components was good and the surface was smooth.When the volumn ratio of water and ethanol was 7:3,the blended films had the highest mechanical performances and low water absorption performances.关键词
