AI Technical Summary
Existing inorganic fillers are prone to loss in high-concentration alcohol environments, leading to a decrease in the fuel barrier properties and mechanical properties of ECO materials. Furthermore, the multi-layer composite structure is prone to interlayer delamination, failing to meet stringent vehicle evaporative emission regulations.
By grafting flexible polymer segments onto the surface of layered inorganic fillers, covalent ether bonds are formed to enhance the interfacial bonding between the filler and the ECO matrix. The modified layered filler is then uniformly dispersed in the ECO matrix to form a physical barrier and reduce the diffusion channels of small fuel molecules.
It effectively maintains interfacial bonding, prevents interfacial debonding and filler delamination, improves fuel barrier properties and mechanical performance, and meets stringent vehicle evaporative emission regulations.
