Fluorinated surfactants are highly efficient surface-active agents that incorporate fluorine atoms—typically in perfluorinated or partially fluorinated alkyl chains—into their molecular structure. Due to the exceptionally strong carbon–fluorine bond, these surfactants exhibit superior performance over traditional hydrocarbon-based surfactants in aspects such as surface tension reduction, wetting and spreading, anti-fouling, and water/oil repellency. Even at very low concentrations, they can significantly lower surface tension, making them ideal for applications demanding high surface performance, including electronics manufacturing, fine chemicals, functional coatings, and fire suppression systems.
