“…The samples were coated with gold using BAL-TEC SCD 005 sputtered coated machine for 3 minutes. FTIR spectrum of the films were obtained from Perkin Elmer Spectrum One FTIR Spectrophotometer equipped with Attenuated Total Reflectance (ATR) from 400 to 4000 cm -1 with resolution of 4 cm -1 and 16 times of scan rate [14]. The electrochemical impedance measurement of all films were recorded using Hioki 3532-01 LCR Hi Tester in the frequency range of 100Hz -1MHz.…”

“…The measurement was carried out in an Espec Temperature & Humidity Chamber Model SH-241 at temperature of 25 °C and 40% humidity. The films were cut into round shape that fitted the diameter of the electrode and were sandwiched between two stainless steel electrodes of 2 cm in diameter [14]. The bulk resistance (Rb) was obtained from the cole-cole plot and the ionic conductivity of the polymer electrolyte films was calculated as…”

“…So, several modifications have been carried out to reduce the phase separation of the blend. This includes adding inorganic filler such as SiO2 nanoparticles [14]. Awkwardly, the filler tends to agglomerate due to the formation of hydrogen bonding between Si-OH groups with the surrounding moisture.…”

Carboxylic acids of various carbon chain lengths (Cn); i.e. butanoic acid (C4), octanoic acid (C8), dodecanoic acid (C12) and hexadecanoic acid (C16) have been used to organically modify silicon dioxide (SiO2). The acid modification involve replacing the hydrogen atom of the silanol group (Si-OH) of SiO2 with the RnCOO-of the acid via esterification technique. SiO2 and acid modified SiO2 (MoCn-SiO2) were used as filler in preparation of polymethyl methacrylate/50% epoxidized natural rubber electrolytes containing SiO2 (PEL-SiO2) and MoCn-SiO2 (PEL-MoCn-SiO2) via solvent casting method with lithium tetrafluoroborate (LiBF4) as dopant salt. Field-emission scanning electron microscopy (FESEM) analysis of PEL-SiO2 and PEL-MoCn-SiO2 films show LiBF4 accumulated to the fillers. Fourier-transform infrared spectroscopy (FTIR) analysis confirmed formation of hydrogen bonding between LiBF4 with fillers and polymers in the polymer electrolyte films. Interestingly, the ionic conductivity of PEL-MoCn-SiO2 films increases as the Cn of acids increased with the highest ionic conductivity of 5.56 x 10-7 Scm-1 was achieved in PEL-MoC12-SiO2 film.
