The majority of organic ultraviolet (UV) absorbers that available on the market today are synthetic chemicals derived from petroleum. This increases the growing need for UV absorbers with high safety and low environmental effects. Currently, there has been an increasing interest in developing alternatives to fossil fuel-based products since these products are derived from nonrenewable resources and associated with global warming. Due to its excellent UV absorption ability, lignin is a promising raw material for the replacement of organic UV absorbers. Lignin is a natural UV-blocking material due to its aromatic structure and the presence of numerous phenolic, ketone, aromatic building blocks and intramolecular hydrogen bonds. The present review focuses on providing a comprehensive insight into lignin-based UV aging resistance. These insights are including the UV aging mechanism of polymers, the potency of lignin as UV absorbers, and the utilization of lignin as UV aging resistance in polymers. Therefore, the role of lignin in improving UV aging resistance in polymer materials was detailed and explored.
