“…Earlier studies observed that upon addition of various plasticizers amorphous humps are enhanced and they attributed to the disruption of hydrogen bonds that built up the crystalline phase through the polymer host [ 29 , 32 , 33 , 38 ]. The ionic conductivity is robustly affected by the nature of crystallinity, and the amorphousness of the materials [ 39 ]. Remarkably, the ionic conductivity of the PVCH films expected to be enhanced when the amorphous nature was increased [ 40 ].…”

In this study, plasticized films of polyvinyl alcohol (PVA): chitosan (CS) based electrolyte impregnated with ammonium thiocyanate (NH4SCN) were successfully prepared using a solution-casting technique. The structural features of the electrolyte films were investigated through the X-ray diffraction (XRD) pattern. The enrichment of the amorphous phase with increasing glycerol concentration was confirmed by observing broad humps. The electrical impedance spectroscopy (EIS) portrays the improvement of ionic conductivity from 10−5 S/cm to 10−3 S/cm upon the addition of plasticizer. The electrolytes incorporated with 28 wt.% and 42 wt.% of glycerol were observed to be mainly ionic conductor as the ionic transference number measurement (TNM) was found to be 0.97 and 0.989, respectively. The linear sweep voltammetry (LSV) investigation indicates that the maximum conducting sample is stable up to 2 V. An electrolyte with the highest conductivity was used to make an energy storage electrical double-layer capacitor (EDLC) device. The cyclic voltammetry (CV) plot depicts no distinguishable peaks in the polarization curve, which means no redox reaction has occurred at the electrode/electrolyte interface. The fabricated EDLC displays the initial specific capacitance, equivalent series resistance, energy density, and power density of 35.5 F/g, 65 Ω, 4.9 Wh/kg, and 399 W/kg, respectively.

“…Salah satu cara untuk meningkatkan konduktivitas ionik kitosan disamping penambahan garam-garam adalah dengan menambahkan filler oksida berukuran nano seperti TiO 2 , monmorillonit SiO 2 , Al 2 O 3 dan ZrO 2 (Navaratnam, Ramesh, and Basirun 2011; Winie et al 2014;Yulianti et al 2013;Aziz and Abidin 2014). Selain itu teknik implantasi ion juga bisa dikembangkan untuk meningkatkan konduktivitas ionik kitosan (Yulianti, Karo, dan Susita 2012). Akan tetapi konduktivitas yang diperoleh relatif masih rendah sekitar 10 -5 S/cm.…”

ABSTRAK OPTIMALISASI KONDUKTIVITAS IONIK ELEKTROLIT POLIMER BERBASIS KOMPOSIT KITOSAN-ZIRKONIA/LITIUM PERKLORAT DENGAN PENAMBAHAN GLISEROL.Untuk meningkatkan nilai konduktivitas ionik elektrolit polimer, telah dilakukan modifikasi terhadap sistem komposit kitosan-ZrO2/LiClO4 dengan menambahkan gliserol sebagai plasticizer. Pembuatan lembaran elektrolit polimer dilakukan dengan metode casting, setelah seluruh komponen dicampur secara bertahap dan diaduk dengan pengaduk magnet. Penambahan plasticizer dilakukan dengan berbagai komposisi yaitu antara 0% (g/g) sampai dengan 80% (b/b). Elektrolit polimer kemudian dikarakterisasi meliputi struktur mikro dengan difraksi sinar-X (XRD), sifat mekanik dengan uji tarik menggunakan UTM, spektrometer impedansi (LCR-meter) dan pengukuran jumlah transferensi ion. Hasil karakterisasi dengan XRD dan uji sifat mekanik menunjukkan bahwa elektrolit polimer menjadi semakin amorf dan elastis dengan penambahan plasticizer. Penambahan plasticizer yang optimal adalah sebanyak 60% (b/b) dimana pada komposisi tersebut masing-masing diperoleh bilangan transferensi ion tertinggi 0,85 dengan nilai konduktivitas ionik 3,52 x 10 -4 S/cm.

“…The solid polymer electrolytes (SPEs) are known to be very attractive due to many advantages such as non‐leakage, volumetric stability, and solvent‐free condition. Furthermore, they have a wide electrochemical stability window, simple preparation in different forms, and good mechanical and adhesion properties to different substrates . SPE consists of a salt dissolved in a polymer matrix that results in an ionically conducting solid solution .…”

Natural polymers are widely used as matrices for solid polymer electrolytes (SPEs) in electrochemical devices due to their richness in nature, low cost, and biodegradation properties. Xanthan gum (XG) is a natural polymer obtained from microbial origin and when dissolved form transparent solution with high viscosity and stability even in different temperature conditions. This article describes the synthesis of XG-based SPEs with proton conduction. These new materials were obtained by crosslinking XG with glutaraldehyde, plasticized with ethylene glycol, and doped with acetic acid as ions source. The ionic conducting membranes, casted from this polymer solution, showed a high ionic conductivity of 7.93 3 10 25 S cm 21 at room temperature, a microscopically homogeneous surface, thermal stability, and predominantly amorphous structure. These results prove that XG-based SPEs are very promising new materials that could be applied in modern electrochemical devices.
