          摘要:

          纖維素是自然界儲量最豐富的可再生生物質資源,其綠色高值化利用在實現“雙碳”和“循環經濟”目標中起到不容忽視的重要作用。纖維素的綠色高效溶解是實現其高值化利用重要途徑之一。眾多纖維素溶劑體系存在價格昂貴、毒性和環境威脅、溶解工藝復雜、溶解效率低、溶劑回收困難和能耗高等問題。金屬鹽溶液體系具有高穩定性、價格便宜,同時溶解纖維素速度快、溶解工藝簡單等特點,是更具應用前景的低成本綠色溶劑。本文綜述了不同金屬鹽溶液溶解纖維素的溶解機理,總結了影響溶解性能的關鍵因素,并進一步綜述了基于不同金屬鹽溶液溶解纖維素在薄膜材料、凝膠材料以及復合材料等領域的應用研究進展,總結并展望了金屬鹽溶液在纖維素溶解及功能化應用方面的優勢、不足及發展方向,以期為纖維素的綠色高效溶解的研究與應用提供參考與借鑒。

          Abstract:

          Cellulose is the most abundant renewable biomass resource in nature, and its high value green utilization plays an important role in realizing the goal of "double carbon" and "circular economy". The green and efficient dissolution of cellulose is one of the important ways to realize its high value utilization. Many cellulose solvent systems are expensive, toxic and environmental threats, complex dissolution process, low dissolution efficiency, difficult solvent recovery and high energy consumption. Cellulose metal salt solution system has the advantages of high stability, low price, fast dissolution speed, simple process and so on. It is a low-cost green solvent with more application prospects. This paper reviews the dissolution mechanism of cellulose dissolved by different metal salt solutions, summarizes the key factors affecting the dissolution performance, and further reviews the application research progress of cellulose dissolved by different metal salt solutions in thin film materials, gel materials and composite materials. The advantages, disadvantages and development direction of metal salt solution in cellulose dissolution and functional application are summarized and prospected, in order to provide reference for the research and application of green and efficient cellulose dissolution.
