Preparation and Characterization of Polythiophene Containing Al₂O₃Nanoparticles Using Sodium Dodecylbenzenesulfonate as a Surfactant

Abstract

Nanocomposite and composite PTh/Al 2 O 3 nanoparticles were prepared in aqueous media by using sodium dodecylbenzenesulfonate (DBSNa) as a surfactant. Al 2 O 3 nanoparticles were coated with PTh using a chemical oxidative polymerization method. The chemical structure and surface morphology of PTh/Al 2 O 3 nanoparticles were characterized by X-ray diffraction and scanning electron microscopy. The results indicate that the type of surfactant and Al 2 O 3 influence the size and homogeneity of particles.

The modified polythiophene‐Cu NPs composites for Pb(II) ions removal from aqueous solution

“…Moreover, PTh has facile synthesis and electrical conductivity, combined with well mechanical characteristics and processing advantages 27 . These unique advantages make it to have different important application areas such as removal of heavy metals, 28–31 solar cells, 32 catalyst support materials, 33 sensors, 34 photocatalytic degradation, 35 light emitting diodes and electrochromic devices 36–43 . Polythiophenes have suitable molecular structure, surface area and the number of sites that let them to interact with the pollutant materials such as heavy metals 44 …”

Synthesis and characterization of conductive polyaniline nanocomposite containing fluorene

“…In recent years, there has been great interest in the production, characterization, and application of conductive composites such as polyacetylene, polythiophene, polypyrrole (PPy), and polyaniline (PANI) because of their potential applications in numerous areas, such as gas sensors, biotechnology, information storage, microelectronic devices, antistatic coating, electromagnetic interference shielding, optical devices, redox capacitors, and electrochemical displays, because of their high intrinsic conductivity, environmental stability, easy synthesis and processing, and good cyto-compatibility. [1][2][3] In the family of conducting polymers, it is well known that PANI is expected to play an important role in practical applications, such as electrode materials, sensors, electromagnetic shielding material, anticorrosive material, electrochromic originals, selective permeation membranes, light-emitting diodes, plastic welding, and microwave absorbing material, because of their cheap monomer material, good oxidation resistance, high-temperature resistance, redox reaction property, electrochromic color effect, high capacitance, good environmental stability, ease of preparation and antibacterial properties, and lightweight. [4][5][6] In recent decades, several reports have been published on the synthesis of PANI nanocomposites with inorganic nanoscale materials such as zinc oxide, 7 titanium oxide, 8 gold, 9 silica, 10 LiNi ferrite, 11 and nickel and zinc ferrite 12 as well as PANI composites with organic macromolecules such as polystyrene, 13,14 poly(ethylene-co-acrylic acid), 15 and polyamide.…”
