The presence of the β PVDF phase in gel-2 (Figure ) is noteworthy. Segregation of -CF2 and -CH2 groups on opposite sides of the polymer in that phase facilitates cation hopping, which can improve cation mobility. Although the β PVDF phase can be difficult to obtain, its formation can be fast tracked by simply incorporating an ILE into PVDF or PVDF-HFP. The ILs used in those cases (e.g., [BMIM][PF6] and EMIMTFSI) have relative dielectric constants (12-16) similar to the IL in gel-1 (ε (PYR14TFSI) = 14.7). The fact that gel-1 was used as a template for gel-2 could help explain the appearance of the β phase in gel-2. Alternative explanations are discussed in the SI.
