Interfacial challenges in unconventional oil extraction include heavy oil–water–solid multiphase separation and corrosion inhibition. Herein, a novel strategy based on interfacial hydrogen bonding reconstruction is proposed for constructing multifunctional interfacially active materials (MIAMs) to address multi-interfacial separation needs. A simple one-pot method is applied to successfully synthesize four different MIAM varieties, integrating site groups (–NH, O[dbnd]S[dbnd]O, –COOH, and Si–O–Si) with multiple hydrogen bonds (HBs) into allyl polyether chains. The results indicate that all synthesized MIAMs excel in demulsification, detergency, and corrosion inhibition simultaneously, even at 25 °C. Their dehydration efficiency for different water-in-oil emulsions (even heavy oil emulsion) surpasses 99.9 % even at 16 °C, showing their excellent energy-saving potential for field applications. Furthermore, they demonstrate effective, nondestructive static cleaning (up to 86 %) of adhered oil from solid surfaces at 25 °C and provide corrosion inhibition effects (up to 92.09 %) on mild steel immersed in saturated brine. Mechanistic tests reveal that incorporating multiple HB sites in MIAMs dramatically enhances their effectiveness in interfacial separations. Based on these findings, an HB-dominated noncovalent interaction reconstruction strategy is tentatively proposed to develop advanced materials for low-carbon, efficient interfacial separations.
