Harnessing the Potential of Amide-Linked Gemini Surfactants for Corrosion Inhibition and Antimicrobial Activity: From Molecular Design to Functional Performance.

Gemini surfactants, also called Gemini, especially those with quaternary ammonium head groups, are recognized for their distinctive aggregation behavior and enhanced structure-activity relationships. The unique dual-head and dual-tail structure of Gemini grants them superior surface activity, allowing them to effectively lower surface and interfacial tension. To investigate the self-assembly behavior and surface-active properties that make them suitable as anticorrosion and antimicrobial agents, a series of cationic Gemini featuring amide bonds and varying alkyl chain lengths were synthesized.
