Abstract The invention relates to the technical field of lignin nano material preparation, in particular to a composite lignin nano microsphere and a preparation method thereof. The preparation method comprises the following steps: dissolving lignin in a water-based solvent, carrying out ultrasonic dispersion, fully mixing and reacting with a nano-cellulose solution added with a cross-linking agent, an initiator and citric acid, and then carrying out rotary evaporation and freeze drying to obtain the composite lignin nano-microspheres. The whole preparation method is simple and easy to operate and low in cost; the composite lignin nano-microspheres prepared by the method have the advantages of uniform morphology, uniform dispersion, no aggregation, good stability, hollow opening, good biocompatibility, and small harm to human body and environment. 本申请涉及木质素纳米材料制备技术领域,尤其涉及一种复合木质素纳米微球及其制备方法。该制备方法包括:将木质素溶于水性溶剂后,经过超声分散后与加有交联剂、引发剂及柠檬酸的纳米纤维素溶液充分混合反应,然后通过旋转蒸发、冷冻干燥得到复合木质素纳米微球。整个制备方法简单易操作,成本较低;通过此方法制备的复合木质素纳米微球,形貌均一、均匀分散无聚集、稳定性
