Fluorocarbon surfactants are a type of substance that can significantly reduce the surface tension of solvents at extremely low concentrations. Fluorocarbon surfactants are the most important type of special surfactants, referring to the hydrogen atoms in the hydrocarbon chain of hydrocarbon surfactants being completely or partially replaced by fluorine atoms, that is, the fluorocarbon chain replaces the hydrocarbon chain. Therefore, the non-polar groups in surfactants not only have hydrophobic properties but also have unique oleophobic properties.
Fluorocarbon surfactants have a wide range of applications, mainly including:
1. Surface treatment agent: Fluorocarbon surfactants can be used to treat the surfaces of various materials, forming a protective layer that is resistant to oil, water, and corrosion, and improving the surface performance of objects.
2. Coatings and coating materials: Due to their hydrophobicity and non adhesiveness, fluorocarbon surfactants are often used as additives in coating materials, which can give coatings good water, oil, and corrosion resistance.
3. Surfactants: Fluorocarbon surfactants can also be used as surfactants such as detergents, foaming agents, emulsifiers, etc. Due to their low surface energy and chemical inertness, they have unique advantages in cleaning and surface treatment.
The preparation methods of fluorocarbon surfactants generally include fluorinated alkylation, fluorinated arylation, and fluorinated allylation. These methods can prepare fluorocarbon surface activity by introducing fluorine atoms into chemical reactions
