Although the oil-and-water repellent effect is excellent, long-chain perfluoroalkyl monomers (PFCs) and C8-PFCs (perfluorocarbons containing 8 carbons) with more than 6 carbon atoms and usually 8 carbon atoms are generally used as the oil-and-water repellent agent, and the longer the chain of the carbon atoms in the perfluoroalkyl group is, the better the oil-and-water repellent performance is, because the fluoropolymer can form a film on the paper fiber, the long side chain containing fluorine in the film can be stretched and aligned on the interface, and the film can significantly reduce the surface energy of the substrate and is smaller than that of a common liquid, so the oil-and-water repellent performance is achieved.
However, in recent years, it has been found that these long-chain fluoroalkyl compounds generate ammonium perfluorooctanoate/perfluorooctane sulfonate (PFOA/S) which is harmful to the environment and human body during use, and low dosage of these substances has bioaccumulation property, especially when they are in contact with food for a long time, and they are highly toxic to human body, and may cause diseases such as hereditary, reproductive, developmental, liver and cardiovascular diseases.
