Research Progress on Polymerization and Curing Technology of Urushiol and Its Application in Functional Polymers
Urushiol was the common plant polyphenol in China.It was isolated and purified from the lacquer by lacquer tree secretion.The structure contained active groups such as benzene ring,ortho/meta bisphenol hydroxyl group and long(unsaturated)alkane side chain(C15-C20).In recent years,the application of urushiol in membrane functional material technology had made rapid progress.In particular,the preparation of urushiol functional polymers by chemical polymerization and curing technology had been widely used in membrane surface/interface engineering,adhesives,hemostatic agents,and other fields.It was one of the important ways to realize the resource utilization and quality improvement of raw lacquer.This article reviewed the recent domestic and foreign research on the polymerization and curing mechanism of urushiol,as well as heating curing,ultraviolet curing,laccase biomimetic catalysis,metal coordination chelation,organic blend cross-linking,sol-gel reaction,electrospinning and other urushiol curing polymerization technologies.The research progress and main problems of urushiol functional polymers in the application of functional materials such as anti-corrosion coatings,hydrophobic coatings,hemostatic and antibacterial coatings were summarized,which provided theoretical basis and development direction for the commercial application of urushiol functional materials.
