Abstract
En 中文
• Oxidative aging shifts asphaltenes to weakly concentration-dependent clusters. • Oxidation increases asphaltene polarity and strengthens interfacial adsorption. • Oxidation weakens interfacial films, accelerating oil droplet coalescence. • DFT and AIMD reveal adsorption via hydrogen bonding and π–π interactions.
