Laser–induced amorphous metal oxide is increasingly applied to enhancing interfacial bonding in metal–polymer hybrid materials. This work aims explore physicochemical interactions between and polymer understand its mechanism from the micro–nano scale. Scanning electron microscopy X–ray photoelectron spectroscopy were used investigate properties of laser–induced aluminum oxides on alloy surfaces. A well–infiltrated layer incompletely oxidized at enhanced alloy–polymer interface was characterized using transmission microscopy. Subsequently, molecular dynamics simulations density functional theory calculations utilized interaction process polymers role interface. It demonstrated that generate strong electrostatic with polymer, ionic ionic–covalent bonds are main chemisorption under low reaction energy barrier, which reveals origin favorable infiltration high reactivity oxides. Furthermore, clarified based discovery anchoring effect resulting polymer.
