A nanocellulose-gelatin (bacterial cellulose gelatin (BCG)) film was developed by a supplement of gelatin, at a concentration of 1%-10% w/v, in a coconut-water medium under the static cultivation of . The two polymers exhibited a certain degree of miscibility. The BCG film displayed dense and uniform homogeneous structures. The Fourier transform infrared spectroscopy (FTIR) results demonstrated interactions between the cellulose and gelatin. Incorporation of gelatin into a cellulose nanofiber network resulted in significantly improved optical transparency and water absorption capacity of the films. A significant drop in the mechanical strengths and a decrease in the porosity of the film were observed when the supplement of gelatin was more than 3% (w/v). The BCG films showed no cytotoxicity against Vero cells.
通过在椰子水培养基中静态培养，添加浓度为1%-10%（w/v）的明胶，制备了一种纳米纤维素-明胶（细菌纤维素明胶（BCG））薄膜。这两种聚合物表现出一定程度的互溶性。BCG薄膜呈现出致密且均匀的均质结构。傅里叶变换红外光谱（FTIR）结果表明纤维素与明胶之间存在相互作用。将明胶掺入纤维素纳米纤维网络中可显著提高薄膜的光学透明度和吸水能力。当明胶添加量超过3%（w/v）时，观察到薄膜的机械强度显著下降且孔隙率降低。BCG薄膜对Vero细胞无细胞毒性。
