Abstract

Abstract:

Small-scale lignin particles are new products for high-value utilization of lignin. Due to their excellent physicochemical properties and potential application value, such as non-toxicity, corrosion resistance, antibiosis and antioxidation, they have attracted extensive attention and have been studied and developed by scientific researchers. In this paper, the preparation technologies of small-scale lignin particles, including self-assembly method, antisolvent method, interfacial polymerization/crosslinking method, high shear homogenization method, ultrasonic wave method, ultrasonic spray freezing method, microbial method and enzymatic method, etc., were reviewed. Subsequently, the preparation principle, preparation conditions and product characteristics of small-scale lignin particles prepared by different lignin raw materials and different methods were expounded. Then, the main preparation process parameters, physical and chemical characteristics and main size characterization methods of small-scale lignin particles were summarized and compared. In addition, the research progress on the application of small-scale lignin particles in ultra-violet protection, composite materials and drug delivery carriers was briefly introduced. In the end, the main problems existing in the preparation and application of small-scale lignin particles at the present stage and the future development direction were analyzed compendiously in order to provide reference for the research and development of lignin in forest resource deep processing and biomass-based nanomaterial science and technology.
