“…Consequently, the free volume originated from the inefficient packing of disordered chains in the amorphous regions [45] increases, and ionic species become more mobile following micro-Brownian motion [46] to contribute to higher conductivity. The ionic conductivity of all GPE-IL increased with the temperature and achieved nearly $10 À2 S cm À1 (for sample containing 7.5 wt.% [bdmim]BF 4 ) at 363 K, which suggests that the ion mobility is closely associated with the enhancement of segmental movement in the polymer chain within the amorphous region [47][48].

“…These nano-particles can interact with two Lewis bases, the PMMA/PLA blend oxygen atoms and BOB, which arises from the Si-O stretching vibration. As a result of this interaction, the OH groups on the nano-particle surface of SiO 2 establish hydrogen bonds with the oxygen atoms of polymer matrices, indicating the presence of Lewis acid-base interactions [32,33].…”

In the present work, varying silica nanofillers (SiO2) compositions were successfully introduced into PMMA/PLA-20%LiBOB amorphous gel polymer electrolyte (GPE) systems. FTIR analysis unveiled subtle alterations in wavenumber shifting and intensity at several highlighted peaks, indicating the occurrence of molecular interactions within the GPE. XRD analysis revealed a notable reduction in crystallinity, particularly up to 6 wt.% SiO2, implying that the presence of nanofillers influenced complexation ability and amplified amorphous regions. Meanwhile, TGA analysis confirmed that the 6 wt.% SiO2 sample exhibited the least mass loss, affirming its exceptional thermal stability and proved the increase in ionic conductivity until the maximum value of 2.19×10-3 S cm-1 for samples up to 6 wt.%. The TNM testing resulted in a notably high lithium-ion transference number, which indicates the practical viability of this composition for application in lithium-ion batteries and provides promising enhanced electrochemical performance.

“…The value of n > 1 shows the caged hoping of ions, [ 29 ] 0 < n < 1 shows the correlated hopping and n = 0 shows the hopping free motion of ions. [ 30,31 ] Herein the HFP and doped HFP shows n < 1 which indicates the correlated hopping type ionic transport in the polymer matrix. The value of DC conductivity, power exponent “ n ” and value of R square for HFP, HFP‐BF 3 , and HFP‐AlCl 3 are shown in Table 1.…”

Perfect crisscross chain arrangements with high inter‐chain H‐bonding structure of conjugated polyamides are capable of inter‐chain proton transfer and this property of conjugated polyamides makes them semiconducting material. To establish this, we synthesized in situ HCl doped Hydrazine‐Fumaryl Polyamide (HFP) material via the condensation polymerization method. HFP was further modified by doping with Lewis acids BF3 and AlCl3 to increase the amorphous nature and ionic conductivity. Among the synthesized material, HFP–AlCl3 showed the highest amorphous property with the best bulk conductivity in the order of 10−5 S/cm at room temperature. HFP and doped HFP showed correlated hopping type (n < 1) ionic dynamics in the polymer matrix. There was a high amount of charge associated with the polymer matrix (>106 F/m) with negligible electrode‐electrolyte effect contribution. These properties of materials can make them useful in the field of organic voltaic and fuel cell applications.
