纤维素纳米纤维（CNF）是一种环境友好的增强纤维，其与塑料的相容性引起了广泛的关注。在这项研究中，我们开发了一种简单的方法来制备由纳米原纤化细菌纤维素（NFBC）增强的醋酸纤维素（CA）复合材料直接从水溶胶。我们的方法的关键步骤是利用水/有机混合溶剂来保持NFBC的良好分散和CA的良好溶解，沿着该混合溶剂的蒸发而没有NFBC的显著聚集。这种简单的技术改善了NFBC在复合膜中的分散性，并显着提高了其机械强度。
Cellulose nanofibers (CNFs) are potential candidates as environmentally friendly reinforcing fibers, and their compatibilization with plastics has attracted widespread interest. In this study, we developed a simple method to prepare a cellulose acetate (CA) composite reinforced by nanofibrillated bacterial cellulose (NFBC) directly from an aqueous sol. The key steps of our method were the utilization of a water/organic mixed solvent to maintain a good dispersion of the NFBC and good dissolution of CA, along with the evaporation of this mixed solvent without significant aggregation of the NFBC. This simple technique improved the dispersibility of the NFBC in the composite film and significantly enhanced its mechanical strength.
