Fluorocarbon surfactants- A class of substances that can significantly reduce the surface tension of a solvent at very low concentrations . Fluorocarbon surfactants are the most important species of specialty surfactants, which means that the hydrogen atoms in the hydrocarbon chains of the hydrocarbon surfactants are totally or partially replaced by fluorine atoms, that is, the fluorocarbon chains replace the hydrocarbon chains. Therefore, the surface The non-polar groups in the active agent are not only hydrophobic but also oleophobic.
Fluorocarbon surfactants are classified as anionic, cationic, nonionic, ampholytic fluorocarbon surfactants, as well as other types of fluorocarbon surfactants such as silicon-containing fluorocarbon surfactants, hybrid surfactants, long chain type surface-active Agents and non-hydrophilic fluorocarbon surfactants.
