“…These composites possess unique properties, which do not exist for either inorganic component or polymer alone. Nanocomposites attract considerable attention and comprise a significant part in the field of portable devices because of their low cost, high sensitivity, fast response, and relative simplicity [7–14].…”

The interest to ferrite nanoparticles (NPs) is thriving because of their unique applications in life industry. Doping of rubber composites by nanoparticles results in a novel characteristics which is not exist either in the ferrite or rubber alone. In this study, zinc ferrite NPs have been synthesized via sol–gel technique. These nanoferrites embedded into acrylonitrile butadiene rubber (NBR) at different concentrations. The morphology and structure of zinc ferrite and zinc ferrite NPs doped NBR were investigated using X‐ray diffraction and transmission electron microscopy. The influence of zinc ferrite NPs loading on the thermal stability showed that the zinc ferrite enhanced the thermal stability and reduced the rate of thermal degradation of rubber nanocomposites. The effect of zinc ferrite NPs on the mechanical properties of NBR showed that the hardness, tear strength, and tensile stress are improved. The magnetic measurements of these nanocomposites showed that the saturation magnetization is enhanced as the concentration of zinc ferrite NPs increased into NBR nanocomposites. The EPR spectra of zinc ferrite NPs doped NBR indicated that the increase in zinc ferrite NPs content resulted in an increase in the g‐factor and line width. POLYM.

“…One may notice that at fixed temperature the electrical conductivity of the microporous film is higher than non‐imprinted dense polyaniline film by four orders. The temperature dependence of conductivity was interpreted on the basis of Arrhenius equation [27–30]. The activation energy values, E a , for both films have been calculated.…”

The solicitude to molecularly imprinted conjugated polymers is flourishing due to their auspicious properties for a myriad of technological and industrial applications. The preparation conditions strongly affect the structure, optical, thermal, and electrical properties of these polymers. Subsequently, a consistent contemplation is desired to entrench consanguinity between processing stipulations and these variables. Here, molecularly imprinted polyaniline films, based ascorbic acid as a template, have been synthesized via electropolymerization technique. This template has been extracted from the films to create microporous polyaniline films. The morphology and structure of these films were investigated using X‐ray diffraction and Fourier transform infrared spectroscopy. Thermogravimetric test showed an enhancement in the thermal stability of molecular imprinted polyaniline compared with non‐imprinted techniques. The optical measurements showed that the rate of light absorption is increased twice with low transmission and reflection. The electrical conductivity increased by four orders with activation energy of 0.30 eV. The optoelectronic measurements of molecularly imprinted microporous polyaniline films showed that the filling factor and external quantum efficiency are enhanced compared with non‐imprinted polyaniline films.

The influence of polymer on the structure, optical, electrical, and thermal properties of nanoscale fillers is a crucial clue to introduce these novel nanocomposites to service life applications. In the present work, different compositions of cadmium‐doped zinc oxide (CdxZn1−xO) nanopowders, x = 0.1, 0.3, and 0.5, with a uniform particle size of around 8 nm have been synthesized. A fixed amount, 1 wt %, of the prepared nanopowders was blended with aryl poly ether ether ketone (PEEK) by solution mixing to prepare PEEK/CdxZn1−xO nanocomposite films. The structure and morphology of CdxZn1−xO nanopowders and PEEK/CdxZn1−xO nanocomposite films have been characterized using transmission electron microscopy and X‐ray diffraction. The results showed that the particle size of nanoscale filler decreases from 10 nm to 5–7 nm when mixed with PEEK and these nanocomposites have amorphous structure. The thermogravitational analysis results show that a small amount of CdxZn1−xO nanopowders (1 wt %) without surface modification can greatly improve the thermal stability of PEEK. The UV–vis spectra showed that there is absorption peak at 284 nm due to interband π−π* electronic transition. This absorption peak gets shifted toward the longer wavelength region as the concentration of cadmium ions increase in the PEEK matrix. This red shift results in a decrease of the band energy gap. The electrical conductivity of PEEK/CdxZn1−xO nanocomposite films was increased as the cadmium ion increases. The results showed that PEEK/CdxZn1−xO nanocomposite films can be used in thermostat and/or fire alarm devices. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
