Research Abstract

In this study, we synthesized novel ionic liquids bearing perfluoroalkyl groups and tried to solubilize polytetrafluoroethylene (PTFE). Perfluoroalkyl groups were introduced into imidazolium cations and TFSA (bis(trifluoromethanesulfonyl)amide) anion was used as a counter anion. The synthesized ionic liquids were stable at 250 °C. PTFE powder (approx. 5 wt%) was added to the ionic liquids and heated at 250 °C for 48 h. The swelling of the PTFE powder was observed but unfortunately the PTFE powder was not solubilized.
