Research Progress in Natural Phenol-based Dynamic Covalent Polymer Materials
The research progress of natural phenol-based dynamic covalent polymer materials in recent years was reviewed,which mainly included two aspects.Firstly,the basic situation of natural phenolic resources,the development history and characteristics of dynamic covalent bonds were summarized,emphasizing that the dynamic covalent bonds often had two mechanisms of rearrangement and disassociation at the same time.Secondly,the research progress of natural phenol-based polymer materials was reviewed.The involved types included Schiff base,disulfide bond,hydroxy-ester bond,acetal bond,and borate bond.The referred natural phenol-based raw materials mainly included vanillin,eugenol,ferulic acid,urushiol,cashew phenol,naringin,guaiacol,tannic acid,etc.The purpose of this review was to promote the plastic pollution control as well as the research and application of green materials.
