Abstract Lignin is an abundant natural feedstock that offers great potential as a renewable substitute for fossil‐based resources. Its polyaromatic structure and unique properties have attracted significant research efforts. The advantages of enzymatic over chemical or thermal approach to construct deconstruct lignins are it operates in mild conditions, requires less energy, usually uses non‐toxic chemicals. Laccase widely investigated oxidative enzyme can catalyze the polymerization depolymerization lignin. dual nature causes challenge controlling overall direction lignin‐laccase catalysis. In this Review, factors affect laccase‐catalyzed lignin were summarized, evaluated, compared identify key features favor polymerization. addition, critical assessment conditions enable production novel hybrids via grafting was presented. To assess industrial relevance laccase‐assisted valorization, patented applications surveyed challenges opportunities analyzed. Finally, our perspective realizing full laccase building lignin‐based materials advanced deduced from analysis limitations governing grafting.

Fabrication of spherical lignin nanoparticles (LNPs) is opening more application opportunities for lignin. However, dissolution LNPs at a strongly alkaline pH or in common organic solvent systems has prevented their surface functionalization dispersion state as well processing and applications that require maintaining the particle morphology under harsh conditions. Here, we report simple method to stabilize through intraparticle cross-linking. Bisphenol A diglycidyl ether (BADGE), cross-linker that, like lignin, contains substituted benzene rings, coprecipitated with softwood Kraft form hybrid (hy-LNPs). The hy-LNPs BADGE content ≤20 wt % could be cross-linked without altering colloidal stability. Atomic force microscopy quartz crystal microbalance dissipation monitoring were used show internally particles resistant conditions acetone-water binary dissolved unmodified entirely. We further demonstrated covalent 12 an epoxy ring-opening reaction obtain pH-switchable charge. Moreover, ≥30% allowed both inter- cross-linking >150 °C, which enabled waterborne wood adhesives competitive dry/wet adhesive strength (5.4/3.5 MPa).
