摘要
将水溶性甲壳素与用氢氧化钠-尿素-硫脲体系溶解的纤维素共混制膜.红外光谱、扫描电镜、透射比分析表明,当水溶性甲壳素浓度达到10%~15%时,水溶性甲壳素与纤维素具有较好的相容性.共混膜的吸湿率和保湿率分别达到32%和55%左右,并具有良好的抗菌性.
The composite membranes were prepared by blending soluble chitin and cellulose dissolved in the system of sodium hydroxide, urea and thiourea. The results of FT-IR, SEM and transparent rates showed that there was good miscibility between soluble chitin and cellulose in the blended system when the concentration of soluble chitin was 10% --15%. The moisture- adsorption rate and moisture-retention rate of blend membranes with good antimicrobial activities reached 32 % and 55 %, respectively.
