Preparation of polypyrrole (PPy)-derived polymer/ZrO2 nanocomposites

Enhanced tailored of thermal stability, optical and electrochemical properties of PANI matrix containing Al2O3 hybrid materials synthesized through in situ polymerization

“…In a typical experimental procedure, 220 mmol of ANI monomer and stoichiometric amounts of Al 2 O 3 nanoparticles (Al 2 O 3 /ANI monomer = 0.02, 0.04, and 0.06) were added in 25 mL of HClO 4 0.1 M solution under vigorous stirring for ½ h. Then, APS solution (220 mmol) was added dropwise to the on initial solution with stirring. After 24 hours of stirring at 25°C, the precipitate may facilely be separated by filtration, washed with distilled water and ethanol several times, and then dried at 60°C overnight 12–14 . The resultant samples were named as PANI@Al 2 O 3 (2%), PANI@Al 2 O 3 (4%) and PANI@Al 2 O 3 (6%), respectively.…”

“…Electrochemical test were carried out employed a three electrode experiential cell equipped with a Pt auxiliary electrode, working electrode and reference electrode (REH). All the electrochemical studies were carried in 1 M HClO 4 aqueous solution as electrolyte at 25°C 12,13 …”

“…Metal oxides are of intense interest and high performance due to their possessing complementary properties, such as SiO 2 , TiO 2 , Al 2 O 3 , V 2 O 5 , ZnO, SiC, ZrO 2 , MnO 2 , NiO, and Fe 3 O 4 have been widely investigated as the electrode materials for semiconductives 7–17 . Aluminum oxide (Al 2 O 3 ) has been utilized for different applications in industries due to its good physicochemical properties such as lightweight, chemical stability, strength, high‐specific strength, corrosion resistance, with unique thermal properties of thermal stability, and high‐thermal conductivity 18–20 .…”

Preparation of PVA-Based Composites with the Addition of Zinc Oxide Nanoparticles

“…The concentration of glycerine in square function is the parameter which affects the elution of zinc from composites. As found by other researchers, the addition of metallic oxide nanoparticles to a polymer matrix has a great importance in creating their physicochemical and mechanical properties [15]. However, the force needed to tear off the composites from a polypropylene surface is dependent only on the temperature of samples prepared in linear function.…”

Development and characterization of a novel conductive polyaniline-g-polystyrene/Fe 3 O 4 nanocomposite for the treatment of cancer

“…Conducting polymers (CPs) are significant because of their relatively easy processability, thermal and environmental stabilities and tunable electrical conductivities, for example, polyaniline (PANI) [11], polypyrrole (PPy) [12] and polythiophene (PTP) [13,14]. Conducting polymers may have potential applications in areas such as composite materials, tissue engineering, separation membranes, surface-activation materials, supercapacitor, electronic and electro-optic devices, as well as molecular motors [15][16][17].…”
