Dielectric and magnetic properties of conducting ferromagnetic composite of polyaniline with γ-Fe2O3 nanoparticles

Indirect Amperometric Determination of Selected Heavy Metals Based on Horseradish Peroxidase Modified Electrodes

“…The first absorption peak was assigned to π-π * transition of the benzenoid rings and the second was attributed to the transition of benzenoid rings into quinoid rings ( Laska & Widlarz 2005;Kan et al 2006). The results (UV-Vis characterization of PANI) obtained in this study are in close agreement with the literature values (Laska &Widlarz 2005;Kan et al 2006;Singh et al 2008;Mazeikiene et al 2007;Kang, Neoh & Tan 1998). The FTIR absorption band at 3325 cm −1 was assigned to N-H stretching of the amine group of polyaniline (spectrum not shown).…”

Remarkable magnetic enhancement of type-M hexaferrite of barium in polystyrene polymer

“…The authors have used BaM / PS in 2/1 weight ratio because this weight ratio is optimum for magnetic properties as verified in previous works of ferrite-polymer composites. [21][22][23] The BaM-PS composite at BaM/PS weight ratio 2/1 was formed by mixing 3.0 g BaM and 1.50 g PS (Sigma-Aldrich) in 10.0 mL m-cresol (Aldrich, 98%). The solution was being stirring at room temperature.…”

Synthesis and electrochemical investigation of polyindole based fiber as sensor electrode by EIS method

“…PIN has found usage in various areas; such as electronics, microwave absorbing materials, anode material in batteries, anticorrosion coatings, photovoltaics and supercapacitor applications [25][26][27][28]. In spite of the described advantages, PIN has comparatively been less studied in accordance to analogue conductive polymers, as indole monomer has low polymerization efficiency with chemical oxidants and poor mechanical properties due to its tendency on forming a powdery product [29,30]. But, a recent application has found usage of PIN as a fiber polymer electrode for lithium ion secondary battery [31].…”
