Fabrication and characterization of a solid polymeric electrolyte of PAN‐TiO₂‐LiClO₄

Abstract

ABSTRACT:The ionic conductivity of PAN-TiO 2 -LiClO 4 as a function of TiO 2 concentration and temperature has been reported. The electrolyte samples were prepared by solution casting technique. Their conductivity was measured using the impedance spectroscopy technique. The highest room temperature conductivity of 1.8 Â 10 À4 S cm À1 was obtained at 7.5 wt % of TiO 2 filler. It was observed that the relationship between temperature and conductivity were linear, fitting well in Arrhenius and not in Vogel-Tamman-Fulcher equation. The pre-exponential factor, r 0 and E a are 1.8 Â 10 À4 S cm À1 and 0.15 eV, respectively. The conductivity data have been supported by differential scanning calorimeter (DSC) analysis. DSC analysis showed that there was a significant change in glass transition temperature (T g ) with the filler concentration. The SEM micrograph revealed that the TiO 2 particles are dispersed in the electrolyte, thus enhancing its conductivity.

Review on polymer electrolyte in dye-sensitized solar cells (DSSCs)

“…They consist of a variety of classical polymeric materials from synthetics polymer and its blends to bio-based polymer. Namely, PEO (Ren et al, 2002), poly (methyl methacrylate) (PMMA) (Lee et al, 2010e;Yang et al, 2008), polyethylene glycol (PEG) (Joseph et al, 2006), poly(ethylene glycol) methyl ether methacrylate (PEGMA) (Bella et al, 2013a(Bella et al, , 2013b, polyacrylonitrile (PAN) (Taslim et al, 2010;Rika et al, 2009;Rahman et al, 2010), poly(vinyl chloride) (PVC) (Rahman et al, 2004(Rahman et al, , 2007, and poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) Lee et al, 2008b;Priya et al, 2008;Noor et al, 2014). To date, polysaccharides and modified polysaccharides based materials such as chitosan (Buraidah et al, 2010), cellulose (Rudhziah et al, 2015) and carrageenan (Bella et al, 2015) received the attention due to their higher ionic conductivities at room temperature.…”

PEO based polymer-ceramic hybrid solid electrolytes: a review

“…Polymers used in SPEs include polyacrylonitrile (PAN) [ 19 ], PS [ 12 , 13 ], polymethyl methacrylate (PMMA) [ 20 ], polyvinylidene fluoride (PVDF) [ 21 ], polyvinyl pyrrolidone (PVP) [ 22 ], etc. Compared with the other polymers, PEO has many advantages due to its special structure.…”

Polymer‐Based Solid Electrolytes: Material Selection, Design, and Application

“…Except for plasticizers, introduction of inorganic fillers into PAN is another strategy to improve the ionic conductivity. [ 32 ] Wang and co‐workers [ 33 ] also demonstrated that ceramic fillers with modified surfaces could act as sources of charge carriers, leading to an enhancement in ionic conductivity based on the Lewis acid–base theory (Figure 3c). However, PAN has a low solubility in most volatile solvents (e.g., methanol, acetone, and THF).…”
