Abstract The conducting polymer polypyrrole and polypyrrole/ZnO nanocomposites are synthesized by in situ polymerization method at 0°C–5°C temperature with ammonium persulphate as an oxidizing agent. optical band gap of have been studied different weight percentage such 10%, 30%, 50%, room temperature. obtained absorption spectra the wavelength range 200–800 nm T90+ UV/Vis Spectrophotometer. PXRD pattern confirmed hexagonal wurtzite structure ZnO product. particle size is calculated using...
Abstract In situ polymerisation process used for manufacturing polypyrrole (PPy) nanoparticle-reinforced various doping concentration of zinc oxide (ZnO NPs) nanocomposites. Fourier transform infrared(FTIR), Scanning electron microscopy(SEM), Photo luminescence (PL) and UV-vis spectroscopy was to characterise the polymer nanocomposite. The ZnO nanoparticles are distributed throughout PPy matrix as shown in SEM pictures Distinctive peaks Pure metal bond displayed FTIR spectra. Optical...
Green synthesis of multifunctional magnesium oxide nanoparticles (NPs) were prepared by low temperature solution combustion route employing <i>Aloe vera</i> leaves extract as a fuel. The vera </i>leaf extracts acts fuel in the preparation MgO nanoparticles. obtained NPs further characterized various techniques such PXRD, SEM, TEM and UV-visible spectroscopic studies. surface morphologies samples studied with help scanning electron microscopy (SEM). PXRD pattern confirmed cubic (halite)...
The polymer blend composites of PANI with PVDF/KDP have been synthesized by polymerization method. different are obtained adding 10, 20, 30, 40 and 50 wt% KDP were added PVDF 1N concentration during synthesis to get the composites. samples characterized using X-Ray diffraction (XRD). dielectric properties such as constant, loss AC conductivity for at weight percentages studied a function frequency in range 5 Hz–35 MHz room temperature. It is found that permittivity decreased exponentially...
This research work presents the synthesis and characterization of PANI-Al2O3 composites by in situ polymerization technique. Al2O3 content was varied from 2 to 10 wt% steps wt%. Microstructure structural developed conducted using scanning electron microscope X-ray diffraction. The dielectric behavior AC conductivity studied as a function frequency while DC 60 - 200°C temperature range. constant loss were found decrease with increasing values. all increase for values which is attributed...
Abstract Present work depicts the progress of cadmium oxide (CdO)‐polyaniline composites synthesized by chemical oxidative technique. The with change in CdO composition are subjected to structural, electrical, dielectric, and morphology using X‐ray diffraction, AC conductivity, scanning electron microscopy. thermogravimetric analysis carried out study thermal stability, which shows that composite highest concentration displays better stability. electrical conductivity modified polyaniline...
