Dissolution of oligo(tetrafluoroethylene) and preparation of poly(tetrafluoroethylene)-based composites by using fluorinated ionic liquids

Fluorophilic ionic liquids (ILs) showing enhanced compatibility with poly(tetrafluoroethylene) (PTFE) have been newly synthesised. The as-designed ILs contributed both to the dissolution of PTFE oligomers and to the preparation of composites with PTFE with no fear of bleed-out of the ILs.
