AI Technical Summary
Acrylic coatings have insufficient adhesion on non-polar or low surface energy substrates. Existing modification methods lead to increased coating brittleness, making it difficult to balance adhesion and toughness.
By using epoxy-modified monomers with sophisticated molecular structures, flexible crown ether rings are chemically synthesized and incorporated into a rigid epoxy framework to form a dynamic interfacial bonding mechanism. The crown ether rings are used as molecular-level dampers to absorb mechanical energy and improve interfacial stress dissipation.
When subjected to external impact or scratches, the coating maintains complete adhesion, preventing the formation of microcracks and improving long-term protective performance and reliability in harsh environments.
