生物基多糖的疏水改性及其在纸基材料中的应用进展

Progress in Hydrophobic Modification of Bio-based Polysaccharides and Their Application in Paper-based Materials

纸基材料具有良好的应用性能,但较强的吸水性严重制约了其在很多领域的应用。采用石油基化合物进行疏水化处理会破坏纸基材料原本的可降解性。因此,目前研究人员更加关注以生物相容性好的生物基多糖作为疏水改性剂原料。本文综述了近年来生物基多糖在改善纸基材料疏水性方面的研究进展,重点介绍了纤维素、淀粉、壳聚糖、海藻酸盐等生物基多糖的疏水改性及其在纸基材料疏水化处理中的应用现状,并对未来发展趋势进行了总结与展望。

Paper-based materials have great application properties,but their strong water absorption seriously restricts their application in many fields.The hydrophobic treatment for petroleum-based products disrupts the original degradability of paper-based materials.Therefore,in recent years,researchers have become more concerned about using polysaccharides with good biocompatibility as raw materials for hydrophobic modification.This article reviewed the research progress of bio-based polysaccharides in improving the hydrophobicity of paper-based materials in recent years,with a focus on the hydrophobic modification of cellulose,starch,chitosan,alginate,and other bio-based polysaccharides,as well as their application status in the hydrophobicity treatment of paper-based materials.It also summarized and prospected the future development trends.
