摘　　要：纤维素作为自然界中天然、可再生、可降解的高分子资源,被广泛应用于各个领域,但纤维素分子内/间的强氢键和形成的高结晶结构使其在实际应用中存在许多问题,往往需要进行改性。低温等离子体技术作为一种新型高效的技术已被引入到纤维素的改性中,主要介绍了低温等离子体技术对纤维素结构(形态结构、聚集态结构、分子结构)和性质(溶解性、热稳定性)的影响以及在纤维素基材料中的应用(纤维素基气凝胶/水凝胶、纤维素基膜/纸)。低温等离子体技术可以有效地对纤维素进行改性,提升纤维素基材料的性能,但具体的改性效果与纤维素原料、等离子体类型及工作条件有关。As a renewable and degradable natural resource, cellulose has been widely used in various fields. However, the formation of strong intra-and intermolecular hydrogen bonds induced a high crystallinity of cellulose, restricting the practical application of cellulose. This review mainly presents the basic information of cold plasma technology, the effects of cold plasma on the structures(morphological structure, aggregation structure and molecular structure) and properties(dissolution and thermal stability) of cellulose, and application of cold plasma in cellulose-based materials(cellulose-based aerogels/hydrogels and cellulose-based films/paper). It is concluded that the cold plasma can effectively modify cellulose and improve the properties of cellulose-based materials. However, the effect of cold plasma mainly depend on the cellulose raw materials, cold plasma generation types and treatment conditions.
