A preliminary investigation of polymer electrolyte based on hexanoyl chitosan, lithium perchlorate (LiClO4) and various filler additives are described in this paper. Hexanoyl chitosan-based nanocomposite polymer electrolytes were prepared using solution casting technique. The effect of filler addition and type of filler on the electrical properties of the prepared electrolyte system was investigated by impedance spectroscopy (IS). The maximum conductivity of 3.06 × 10-4 S cm-1 and 1.96 × 10-4 S cm-1 were achieved for the hexanoyl chitosan-LiClO4-TiO2 and hexanoyl chitosan-LiClO4-SiO2 electrolyte system, respectively. The variations in conductivity observed were discussed quantitatively using the Rice and Roth model from which the concentration of free ions and their mobility were calculated.

Blend Polymer

Blend polymer electrolytes based on PEO:PVP with various wt% of NH4SCN are prepared by simple solution casting method. The prepared polymer electrolytes are characterized using several techniques. The XRD studies confirm the amorphous and crystalline behavior of prepared BPEs. Functional groups present in the systems are confirmed by Fourier Transform Infrared spectroscopy (FTIR) studies. The electrical properties are analyzed by ac impedance technique. The maximum ionic conductivity is obtained for 20wt% of ammonium thiocyanate doped system and it is 1.81×10-5 S/cm-1 . The dielectric properties of polymer films are also studied and discussed.

Solution Casting Technique

Hexanoyl chitosan-based polymer electrolytes were prepared using the solution casting technique. The effect of dimethyl carbonate (DMC) plasticizer on the structural and electrical properties of the prepared electrolyte system was investigated by X-ray diffraction and impedance spectroscopy, respectively. Upon addition of 15 wt. % of DMC, the ionic conductivity was increased to 4.09 x 10-4 S cm-1 from 3.06 x 10-4 S cm-1. The XRD results revealed the variation in conductivity from the structural aspect. For example, sample with lower crystallinity exhibits higher conductivity. The Rice and Roth model was employed to understand the variation in conductivity on the basis of number and mobility of free ions.

This study included the fabrication of    compound (Tl2-xHgxBa2-ySryCa2Cu3O10+δ) in a manner solid state and under hydrostatic pressure ( 8 ton/cm2) and temperature annealing(850°C), and determine the effect of the laser on the structural and electrical properties elements in the compound, and various concentrations of x where (x= 0.1,0.2,0.3 ). Observed by testing the XRD The best ratio of compensation for x is 0.2 as the value of a = b = 5.3899 (A °), c = 36.21 (A °) show that the installation of four-wheel-based type and that the best temperature shift is TC= 142 K  .When you shine a CO2 laser on the models in order to recognize the effect of the laser on these models showed the study of X-ray diffraction of these samples when preparing models with different concentrations of the values ​​of x, the best ratio of compensation is 0.2 which showed an increase in the values ​​of the dimensions of the unit cell a=b = 5.3929 (A °), c = 36.238 (A°). And the best transition temperature after shedding laser is TC=144 K.
