This review summarizes the recent advances in preparing cellulose hydrogels via ionic liquid-based processes and the applications of regenerated cellulose hydrogels/iongels in electrochemical materials, separation membranes, and 3D printing bioinks. Cellulose is the most abundant natural polymer, which has attracted great attention due to the demand for eco-friendly and sustainable materials. The sustainability of cellulose products also depends on the selection of the dissolution solvent. The current state of knowledge in cellulose preparation, performed by directly dissolving in ionic liquids and then regenerating in antisolvents, as described in this review, provides innovative ideas from the new findings presented in recent research papers and with the perspective of the current challenges.
本文综述了基于离子液体法制备纤维素水凝胶的最新进展,以及再生纤维素水凝胶/离子凝胶在电化学材料、分离膜和3D打印生物墨水方面的应用。纤维素是最丰富的天然聚合物,由于对环保和可持续材料的需求,它备受关注。纤维素产品的可持续性还取决于溶解溶剂的选择。如本文所述,通过直接溶解于离子液体然后在反溶剂中再生来制备纤维素的当前知识状态,从最近研究论文中提出的新发现以及当前挑战的角度提供了创新思路。
