“…Due to these properties FAP ILs are entitled as ultrahydrophobic ionic liquids [12,[17][18][19]. The advantageous properties of FAP ionic liquids [20] make them attractive for various applications, namely for liquid-liquid extractions and separations [17,18,[21][22][23], chemical technology [24][25][26][27][28][29], analytics [23,[30][31][32][33][34], electrochemistry [2, 4, 35-37, 40, 41], lubrication [38,39], sensors [31][32], catalysis [42,43], polymer electrolytes [40], the preparation of carbon-based composite materials [44], polymer chemistry [45], membrane technology [46], and the generation of ion beams for electrical propulsion [47]. FAP ionic liquids are robust liquid media that can serve as solvents for chemical reactions with aggressive substances, for instance with elemental fluorine [48].…”
