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.

A consensus was built in the first half of 20th century, which further debated more than 3 decades ago, that wettability and condensation mechanisms on smooth solid surfaces are modified by adsorption organic contaminants present environment. Recently, disagreement has formed about this topic once again, as many researchers have overlooked contamination due to its difficulty eliminate. For example, intrinsic rare earth oxides been reported be hydrophobic non-wetting water. These materials were subsequently shown display dropwise with steam. Nonetheless, follow research demonstrated is hydrophilic wetting water, a transition hydrophobicity occurs matter hours-to-days consequence volatile compounds from ambient The mechanisms, kinetics, selectivity, these empirically known functions substrate material structure. However, govern surface wettability, remain poorly understood. In contribution, we introduce current demonstrating different metals, oxides, other materials, showing they intrinsically hydrophilic. Then provide details focusing (hydrophilicity) (hydrophobicity) somooth compounds. state-of-the-art figure merit mapping exposure function carbon content also developed. addition, analyse recent works address transitions so shed light how such processes affect droplet pinning lateral adhesion. We then conclude objective perspectives an attempt raise awareness regarding phenomenon within engineering, interfacial science, physical chemistry domains.
