Electrical characterization of PVA-based nanocomposite electrolyte nanofibre mats doped with a multiwalled carbon nanotube

Enhanced Thermal and Electrical Properties of Polystyrene-Graphene Nanofibers via Electrospinning

“…Thermal conductivity substantially increased upon the addition of GNP, up to a 630% increase corresponding to 10 wt.% GNPs loading, in line with best results published in the scientific literature ( Figure 5(a)). Figure 5(b) compares the electrical conductivity values of PS-GNP nanofibers with other electrospun mats containing carbonaceous fillers [31,[34][35][36][37][38][39][40][41][42]. The electrical conductivity of PS/GNP nanofibers increased suddenly corresponding to a GNP content below 1 wt.% reaching 1.4±0.6 S/m for 10 wt.% GNP loading.…”

DMA and Conductivity Studies in PVA:NH4SCN:DMSO:MWNT Nanocomposite Polymer Dried Gel Electrolytes

“…Careful examination of modulus data shows that CNT soaked films give rise to dynamic of composite system coupled with transition related to melting of composite electrolyte system in the temperature range 120-160 ∘ C. Existence of dynamic in composite system dispersed with particles of nanodimensions has been earlier reported by Tsagaropoulos and Eisenberg [14]. Increasing CNT content shifts melting related peaks to lower temperature and ultimately convolutes the separate transitions into a broader transition at 6 wt% CNT.…”

“…Thus, efforts have been directed in recent past to develop high performance nanocomposite polymer electrolytes [11,12]. Generally, nanostructural particles like ceramics [12,13] and carbon nanotubes [14] have not only been shown to improve the mechanical properties of gel and solid polymer electrolyte membranes and their nanofibers but they have also provided improved conductivities to allow their usage in sensors, super capacitors, batteries, electronic components, and so forth [15]. Carbon nanotubes (CNTs) are considered as an ideal reinforcement material for polymer nanocomposites [14,15], as the mechanical properties of the polymer composites are strongly influenced by their morphology and crystallization behaviour [16][17][18].…”

Polyvinyl Alcohol Based Solid Electrolyte Film: Synthesis, Characterization and Electrical Properties

“…Since polymer gels encapsulate electrolyte solution within the pores, they generally exhibit a high ionic conductivity in the order of $1 Â 10 À3 S cm À1 or more at room temperature. [1,2] In the recent past, nanostructured inorganic inert particles like Al 2 O 3 , [3] SiO 2 , [4] TiO 2 , [5] ferrites, [6] etc., have been reported as suitable dispersed solids in the development of these electrolytes. Such nanofillers have found applications in energy storage, actuators, scaffold, etc.…”

“…Such nanofillers have found applications in energy storage, actuators, scaffold, etc. Recently, Agrawal and Awadhia [2] have extensively studied polyvinyl alcohol (PVA)-NH 4 SCN gel electrolytes and PVA-NH 4 SCN-Al 2 O 3 fibers with conductivities in order of $10À3 S cm À1 . [7] The present work is to synthesis the proton-conducting polymer electrolytes based on polyvinyl alcohol (PVA) with alum (ammonium aluminium sulfate) in different molar ratios, have been prepared using conductivity water as solvent.…”
