                 摘要:利用木糖驹形氏杆菌发酵生产细菌纤维素(BC),通过 FTIR、XRD、SEM 等对 BC 进行了表征,并对
                 BC 作为面膜基材方面的各项性能进行了全面评价。结果表明,BC 具有超细的三维网状结构,平均直径小于
                 100 nm,结晶度 83.46%,属于典型的Ⅰ型纤维素。相较于无纺布与蚕丝面膜基材,BC 面膜基材具有更优越的

                 Abstract: Bacterial cellulose (BC)  was  produced by  fermentation  of  Komagataeibacter xylinus and
                 characterized by  FTIR, XRD  and SEM. The performances  of BC as substrate for  mask was evaluated
                 comprehensively. The results showed that the BC had an ultrafine three-dimensional network structure with
                 an average diameter of less than 100 nm and a crystallinity of 83.46%, which belonged to typical typeⅠ
                 cellulose. Compared with  non-woven  fabrics and  silk mask  substrates, BC mask substrate had superior
