Plasticized chitosan–PVA blend polymer electrolyte based proton battery

Electrical Conduction Mechanism in Solid Polymer Electrolytes: New Concepts to Arrhenius Equation

“…Chitosan has good film forming ability, porous scaffolds, and hydrogels [8]. Ion-conducting polymer electrolytes based on chitosan have also been reported [9][10][11][12][13][14][15][16]. From the fundamental point of view, ionic conduction in polymer electrolytes is still poorly understood.…”

Ionic conductivity and dielectric studies of LiClO4 doped poly(vinylalcohol)(PVA)/chitosan(CS) composites

“…The solution so obtained was poured onto clean Petri dishes and dried at room temperature. 13 After drying, the films were peeled from the Petri dishes and kept in vacuum desiccators for future use. Thicknesses of the obtained films were in the range of % 100-200 m, measured using Mitutoyo-7327 Dial Thickness Gage of accuracy 0.001 mm.…”

“…As the temperature increases, the ionic mobility increases and Li þ ion starts penetrating into the PVA/CS polymer blend matrix, due to the size of the lithium ion is small (ionic radius of Li þ ¼ 0:92 Å) compared to the short distance between hydroxyl groups of PVA and CS molecules, hence it increases the conductivity. 13,14 Also, as temperature increases, the vibrational energy of segmental motion of polymer molecules operates against the hydrostatic pressure imposed by its neighboring molecules. Consequently, it creates a free volume around the polymer chains, which causes the augmentation in mobility of ions and hence enhances the conductivity with temperature.…”

The microstructure and performance of solid-state hydrogen sensor using CH3COONH4-doped chitosan as electrolyte

“…At the same time, the XRD peaks of Ag and Pt clearly appear in the XRD pattern, which indicates that the surfaces of chitosan electrolyte are metalized after the impregnation and reduction, i.e., the corresponding electrodes have formed. Figure 2 shows the surface morphologies of 40 wt% CH 3 COONH 4 -doped chitosan electrolyte before and after Figure 2a shows that the chitosan membrane exhibits a rough surface initially that indicates the occurrence of phase separation [23]. After the impregnation-reduction process, Pt electrode and Ag electrode are homogeneously deposited on respective side of the electrolyte and show a porous structure, as shown in Fig.…”
