Microstructural, optical, AC dielectric impedance, and conductivity properties of pure PVA and PVA: NaSe SCF samples doped with various NaSe salt fillers were investigated. The XRD study confirmed the semicrystalline structure of the PolVA:NaSe SCF samples which explicated the semi-crystalline nature of the pure PolVA as a matrix.

New polymeric phthalocyanine moieties (M = 2H, Zn, Ni, Cu, and Co) were synthesized via polytetracyclomerization reaction of o-bis[3-(3,4-dicyanophenoxy)propyloxy]benzene (3), which can be obtained by the reaction of 4-nitrophthalonitrile with o-bis[(3-hydroxypropyl)oxy]benzene. Aggregation and disaggregation behavior of the polymeric phthalocyanine (5) was studied with some alkali and earth alkali metal cations. Measured intrinsic viscosities of the polymeric phthalocyanines exhibited a substantial decreasing tendency with dilution of the solution.

Excellent conducting solid polymer electrolyte films were prepared by using Polyvinyl alcohol (PVA) and Iron alum through a reactive blending process. The effect of the concentration of the iron alum on the conducting behavior was studied in detail by varying the concentration of the alum in the PVA matrix. The functionality was studied using the Infrared (FT-IR) spectroscopic technique.

PVA/CuI polymer composite samples have been prepared and subjected to characterizations using FT-IR spectroscopy, DSC analysis, ac spectroscopy and dc conduction. The FT-IR spectral analysis shows remarkable variation of the absorption peak positions whereas DSC illustrates a little decrease of both glass transition temperature, Tg, and crystallization fraction, v, with increasing CuI concentration. An increase of dc conductivity for PVA/CuI nano composite by increasing CuI concentration is recoded up to 15 wt%, besides it obeys Arhenuis plot with an activation energy in the range 0.54–1.

This paper presents the results of AC electrical breakdown properties of coconut oil with and without Tertiary Butyl Hydroquinone (TBHQ) antioxidant. Ageing test of transformer oil was conducted according to the standard of IEC-61125 B at 120 oC for 72 h with the presence of copper as a catalyst. Experimental results showed that AC breakdown voltage of coconut oil was comparable to that of mineral oil.
