Abstract

In recent decades, the ozone layer has suffered considerable damage, increasing the entry of ultraviolet (UV) light into the atmosphere and reaching the earth’s surface, negatively affecting life. Accordingly, researchers aimed to solve this problem by synthesizing advanced UV-shielding materials. On the other hand, developing an easy and green strategy to prepare functional materials without standing properties based on naturally abundant and environmentally friendly raw materials is highly desirable for sustainable development. Because biomass-derived materials are sustainable and biodegradable, they present a promising substitute for petroleum-based polymers. The three main structural constituents of the plant biomass-based materials that are naturally available are cellulose, hemicellulose, and lignin. This review details current developments using wood-based products such as cellulose, hemicellulose, and lignin in UV-shielding applications. It will start with assembling the structure and chemistry of cellulose, hemicellulose, and lignin, followed by their contributions to preparing UV-shielding materials. Finally, it will briefly discuss the different processing methods for the design of UV-shielding materials. The wood by-products offer additional opportunities to use the whole tree harvest.
