Polyvinylidene fluoride–hexafluoropropylene (PVdF–HFP)-based composite polymer electrolyte containing LiPF3(CF3CF2)3

Effect of ethylene carbonate in poly (methyl methacrylate)-lithium tetraborate based polymer electrolytes

“…Therefore, the free volume around the polymer chain causes the mobility of ions and polymer segments. Hence, temperature increase causes an increase in ionic conductivity due to the increased free volume and their respective ionic and segmental mobility [26,27].…”

Structural, morphological, thermal, and conductivity studies of magnesium ion conducting P(VdF‐HFP)‐based solid polymer electrolytes with good prospects

“…In HATR‐FTIR spectrum of sample MT10 in Figure 1(c), which contains P(VdF‐HFP) : MgTf (90 : 10), it is observed that there is formation of a new peak at 834 cm −1 . This can be assigned to band that attributes to newly formed amorphous region of P(VdF‐HFP) 14. There are several peaks that have visible decrease in intensity, such as asymmetrical stretching of SO 3 at 1259 cm −1 and characteristic peak of Tf − anion at 1638 cm −1 from Figure 1(a), and also α‐phase of PVdF at 760 cm −1 and 974 cm −1 , together with CF 3 stretching at 794 cm −1 from Figure 1(b).…”

Performance characteristics of guanine incorporated PVDF-HFP/PEO polymer blend electrolytes with binary iodide salts for dye-sensitized solar cells

“…The PVDF-HFP/KI þ TBAI/I 2 exhibited characteristic vibrational bands at 838, 883, 1405, 1417, 2962 and 3018 cm À1 . The vibrational bands appeared at 838 and 883 cm À1 corresponds to the amorphous phase of the polymer [33]. A band at 1405 cm À1 is assigned to the eCF stretching frequency of the polymer and a band at 1417 cm À1 corresponds to the eCH 2 wagging and scissoring mode of vinylidene group of the polymer [29].…”
