An improved frequency dependent AC-conductivity ng of poly(aniline-co-o-fluoroaniline)s (PA-co-o-FAs) has been recorded which are synthesized by in-situ copolymerization of aniline with o-fluoroaniline by oxidation of the monomers mixture (in different molar feed ratios) using aqueous solution of ammonium persulfate as oxidant. The electrical AC conductivity of the copolymers has been measured at...
The sulfonated poly(ether ether ketone) (SPEEK)-barium zirconate (BaZrO3)-based polymer nanocomposite membranes are prepared by solvent casting technique. The composite membranes have been characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), water uptake, swelling, and ion exchange capacity (IEC). The NMR, IEC, and CHNSO analyses...
Among sustainable technologies, TiO2 photocatalysts are promising materials as an alternative to conventional methods that are being used for eliminating problems such as water, air, and environmental pollution originating from industrial waste. In this work, TiO2 film was produced by ultrasonic spray pyrolysis technique and annealed in oxygen, argon, and nitrogen atmospheres. The effect of the annealing...
