Abstract:

Lignin is the second largest natural organic polymer compound in plants after cellulose, which has excellent corrosion resistance, heat resistance, and antibacterial and antioxidative properties. The efficient utilization of lignin resources is of great significance to solve the problems of increasing shortage of fossil resources and environmental pollution. The emergence of lignin nanoparticles (LNPs) has opened up a new way for the development and application of high value-added lignin-based products, which combines the small size effect, surface effect and interface effect of nanomaterials with the excellent characteristics of lignin itself. LNPs have shown potential applications in many fields. Herein, the characteristics and principles of six preparation methods of LNPs were summarized, including self-assembly method, interfacial polymerization/crosslinking method, high shear homogenization method, ultrasonic method, microbial method and enzymatic method. The product composition and final product state of each method were also introduced. Then, the research progress on functional applications of LNPs in adsorbents, colorimetric probes and composite materials (composite films and composite hydrogels) was reviewed, and the development trend of LNPs was prospected to provide ideas for functional development of LNPs.
