- Description
- We form self-assembled monolayer (SAM) of fluoro-carbon chain (C-F_SAM) or hydro-carbon chain (C-H_SAM) to compare their interaction with surfactants containing C-F chains (PFOA, PFOS) or C-H chains (linear alkylbenzene sulphonate, LAS). We observe that the interaction between the C-F_SAM and the C-F chain is much stronger than that between the C-H_SAM and the C-H/C-F chain, and also stronger than that between the C-F_SAM and the C-H chain. The reason is due to the unique fluorophilic interaction among the C-F chains, which is similar with and thus confirm the mechanism for F-extraction. This unique interaction among the C-F chains might shine new light on the development of fluorosurfactant's sensor and remediation.
