Method for preparing degradable nanocellulose reinforced composite material

The invention relates to a method for preparing a degradable nanocellulose reinforced composite material, which comprises the following steps of: (1) pretreating a plant fiber raw material through esterification reaction or alkylation reaction to modify hydroxyl on the surface of cellulose so as to prepare modified plant fiber; and (2) drying the modified plant fiber, and mixing the modified plant fiber with a polymer matrix to obtain the degradable nanocellulose reinforced composite material. 一种制备可降解的纳米纤维素增强的复合材料的方法，其包括：(1)通过酯化反应或烷基化反应，预处理植物纤维原料以对纤维素表面的羟基进行改性，制备改性的植物纤维；和(2)干燥所述改性的植物纤维，和将其与聚合物基质进行混炼，得到可降解的纳米纤维素增强的复合材料。
