Short Chained Fluoro-surfactants; their synthesis and surface activities |
| 초록 |
Fluoropolymers have unique characteristics, for example outstanding thermal stability, low surface energy, excellent dielectric properties, nonadhesive properties and etc.. Emulsion polymerization in practice is a very simple process and perfluorooctanoic acid (PFOA) derivatives, especially ammonium salt have been used as emulsifiers. Due to their high toxicity and bioaccumulation problems, PFOA and theirs derivatives are designated as prohibited substances by environmental groups such as the United States Environmental Protection Agency (EPA). In this study, potential alternatives with shorter fluorocarbon chains have been synthesized. The products were structurally characterized, and their surface active properties were systematically analyzed. It was found that these new surfactants have superior surface activities compared to PFOA derivatives. |
