Key Points

This research aims to enhance the demulsification efficiency of water-in-heavy oil emulsions using polyethyleneimine-modified magnetic carbon nanoparticles.
Prepared polyethyleneimine-modified magnetic carbon nanoparticles (P-MCNs) through surface functionalization.
Evaluated P-MCN demulsification performance in water-in-heavy oil emulsions using the standard bottle test.
Conducted microscopic visualization characterization of the interfacial activity of P-MCN.
P-MCN at 500 ppm achieved effective water removal within 60 minutes at 50 °C.
High interfacial activity of P-MCN was demonstrated, facilitating rapid migration to the heavy oil–water interface.
Demulsification was effective due to disruption of the interfacial film through electrostatic interactions and hydrogen bonding.
