The Role of Renewable Protocatechol Acid in Epoxy Coating Modification: Significantly Improved Antibacterial and Adhesive Properties
A multi-functional epoxy coating was prepared by using protocatechinic acid (PCA) as raw material in this paper
reacting with ethylene glycol diglycidyl ether (EGDE) by one-step method and curing with isophorone diamine (IPDA). It demonstrated outstanding adhesion and antibacterial activity
the highest adhesion was 13.60 MPa
and the highest antibacterial rate was 100%.
Abstract
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.
