“…In nature, lignin can be biomodified by oxidative depolymerization and demethylation through the action of lignin-degradation enzymes produced by bacteria and fungi. [70] The used enzymes to degrade lignin are mainly hydrogen peroxide enzymes (LiP), [71] Mn-dependent peroxidase (MnP), [72] and laccase, [73] among others. The potential mechanisms of these enzymes for lignin degradation are revealed by the degradation routes shown in Scheme 6.…”

Traditionally, phenols used to prepare phenol‐formaldehyde (PF) resin adhesives are obtained from phenolic compounds and various chemicals, which are extracted from petroleum‐based raw materials. Lignin, a sustainable phenolic macromolecule in the cell wall of biomass with an aromatic ring and a phenolic hydroxyl group similar to those of phenol, can be an ideal substitute for phenol in PF resin adhesives. However, only a few lignin‐based adhesives are produced on a large scale in industry, mainly because of the low activity of lignin. Preparing lignin‐based PF resin adhesives with exceptional achievements by modifying lignin instead of phenol is an efficient method to improve the economic benefits and protect the environment. In this review, the latest progress in the preparation of PF resin adhesives via lignin modification, including chemical, physical, and biological modifications, is discussed. In addition, the advantages and disadvantages of different lignin modification methods for adhesives are compared and discussed, and future research directions for the synthesis of lignin‐based PF resin adhesives are proposed.
