Powder coatings have attracted great attention from academia and industry dueto their advantages of no VOC emissions，high coating efficiency，and convenient storage andtransportation. In this paper the research progress of bio-based powder coatings was reviewed， and the use of renewable materials such as furan dicarboxylic acid，lignin，chitosan，isosorbide， and citric acid to prepare film-forming resins，curing agents and fillers was emphaticallydiscussed. It was found that the application of bio-based materials in powder coatings not onlyimproveed product performance but also complied with environmental protection trends. Theapplication prospects of bio-based powder coatings were proposed，providing theoretical basisand practical guidance for promoting the green and sustainable development of the coatingindustry.
