Fluorine chain
WebThe basic structure of PFAS, shown in Figure 1, includes a carbon-fluorine chain, known as the tail, and a functional group at the end of the chain, known as the head (ATSDR, 2024a). Figure 1: Basic structure of Perfluorooctanoic acid (PFOA) (NIHES, 2024). WebPFAS molecules have a chain of linked carbon and fluorine atoms. Because the carbon-fluorine bond is one of the strongest, these chemicals do not degrade easily in the environment. PFOA, also known as C8, has …

WebThe CF 2 groups are equally spaced along the polymer chain; the conformation in the crystalline domains is a zigzag of carbon atoms with the whole chain twisted into a helix. The helical structure arises because fluorine atoms are too large to allow a planar zigzag conformation, so the carbon chain twists to accommodate the steric interaction ...
