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.

本研究中，我们合成了一种新型的含全氟烷基的离子液体，并尝试对聚四氟乙烯（PTFE）进行增溶。将全氟烷基引入咪唑鎓阳离子中，并将TFSA（双（三氟甲磺酰基）酰胺）阴离子用作抗衡阴离子。合成的离子液体在250 °C下稳定。PTFE粉末（约5重量%）加入到离子液体中并在250 °C下加热48小时。观察到PTFE粉末的溶胀，但不幸的是PTFE粉末未溶解。
