It is of great significance to design epoxy coatings with superior antibacterial properties and high adhesive properties,as well as excellent processing,superior durability,and high transparency.However,it is still a challenge because of the common complex design and synthesis.Herein,the bio-based monomer protocatechuic acid(PCA)was used as raw material,the catechol structure with high bonding and antibacterial properties was introduced into the flexible alkane segment of ethylene glycol diglycidyl ether(EGDE)through an efficient,and green method,and it was cured with isophorone diamine(IPDA)to prepare corresponding thermosets.The cured resins exhibited excellent all-around qualities,particularly in bonding and antibacterial.When 30％PCA was added to pure epoxy resin,the adhesion between substrate and coating increased from 4.40 MPa to 13.60 MPa and the antibacterial rate of coating against E.coli and S.aureus could approach 100％.All of this is due to the fact that the catechol structure present in PCA has the ability to interact with various substrates and alter the permeability of bacterial cell membranes.The architecture of this method offers a fresh approach to dealing with the issues of challenging raw material selection and complex synthesis techniques.
