Functionalization of cellulose as lignin to produce high value-added products

摘要

The present invention comprises the steps of preparing an aqueous mixture of lignin particles modified with tall oil fatty acids (TOFA) and reacting the TOFA-modified lignin particles with cellulose particles, a method of covalently attaching lignin to cellulose in an aqueous solution. It is about. The modified cellulose particles obtained are biodegradable and have antimicrobial properties, making them suitable for use as antimicrobial fabric surfaces (sportswear, medical fabrics), tissue adhesives and porous carriers in drug delivery. Furthermore, the material is useful for mass production products such as adhesives and dispersants.
