Applications of Lignin and Characteristics of Spherical Particles
Lignin,as a widely available biomass resource,has immense potential for applications in high-value chemicals,nanomaterials,and biomass-based materials.As one of the most abundant natural polymers on earth,lignin is traditionally considered as an industrial waste in the pulp and paper industry.However,lignin shows great potential in the development of eco-friendly,sustainable,and biodegradable products.This paper reviewed the chemical structure characterization and separation methods of lignin and its applications in various indus-trial fields,such as dispersants,adhesives,coatings,and composite materials,particularly the use of spherical lignin.The paper also pro-vided a perspective on future research directions related to lignin.
