A modified screen-printed carbon electrode (SPCE) has been designed and fabricated for the determination of malondialdehyde (MDA), an important biomarker oxidative stress. Magnetic graphene oxide (MGO) was synthesized coated by a molecularly imprinted polypyrrole (MIPy) preparation novel hybrid nanomaterial ([email protected]). The nanocomposite characterized using different spectroscopic imagi...

Polypyrrole nanoparticles were synthesized by chemical polymerization method using ammonium persulphate as an oxidant. The synthesized polypyrrole nanoparticles were characterized by FT-IR, UV-Visible, FESEM and CV. The structure of polypyrrole nanoparticles were confirmed by FT-IR spectroscopy. The UV-Vis spectra of polypyrrole nanoparticles show π-π* and n-π* transitions. The morphological pr...

The present paper describes the preparation and characterization of Polyvinyl Alcohol-Polypyrrole-Silver Nanocomposite (PVA-PPy-Ag NC) films. The prepared films were conducting, freestanding, flexible, and robust. Silver nanoparticles (Ag NPs) were synthesized from an aqueous solution of silver nitrate using trisodium citrate as a reductant. The casting solution for the films was prepared by in...

We report the structural, morphological, and electrochemical properties of polypyrrole (PPy), copper doped PPy (Cu/PPy), multi-walled carbon nanotubes (Cu/PPy/MWCTs) prepared by oxidative polymerization technique. The incorporation Cu in form nanoparticles composites was confirmed from XRD data. granular morphology observed FESEM micrograph. However, size grains decreased with nanoparticle inse...

The search for lightweight and low-cost anticorrosion coatings is particularly important in coastal environments with high salt humidity. Graphene-based are currently unable to provide long-lasting corrosion protection metals because of their “corrosion-promoting activity”, graphene-like materials, such as molybdenum disulfide (MoS2), beginning be anticipated its ability protect against metals....
