The effect of initiators and oxidants on the morphology of poly [(±)‐2‐(sec‐butyl) aniline] a chiral bulky substituted polyaniline derivative

Abstract

The nano and micro sphere synthesis of chiral bulky substituted polyaniline from monomer (±)‐2‐sec‐butylaniline in bulk and template‐free method (rapid mixing) was done successfully using ammonium peroxydisulfate (APS) and FeCl3·6H2O as oxidants. The effect of initiators such as p‐phenylendiamine and 1,4‐benzenediamine, temperature and concentration of monomer on morphology is demonstrated by scanning electron microscopy (SEM) images. The nano and micro sphere morphology was obtained using initiators. Smallest particles were achieved when 1,4‐benzenediamine was used as initiator in the presence of FeCl3·6H2O as oxidant. By increasing the concentration of monomer more uniform spheres were obtained. Characterization was made via FT‐IR, UV–Vis, 1H and 13C‐NMR spectroscopy. Elemental analysis and electrical conductivity of products are also presented. All analysis data are in good agreement with nigraniline oxidation state of polyaniline.

Polymerization of aniline derivatives by K2 Cr2 O7 and production of Cr2 O3 nanoparticles

“…Potassium dichromate was selected for aniline polymerization as it can play an important role in aniline polymerization as an initiator in addition to the synthesis of polymer composites. PANI, PANA and PAA have high affinity to coordinate with Cr ions due to the presence of benzenoid or quinoid forms . The resulting Cr (III) /polymers (emeralidine base) were used as new precursors for production of chromic oxide nanoparticles based on solid state thermal decomposition route to avoid volatile organic solvents and sophisticated equipment in the synthesis process.…”

Solid-state synthesis of a new core-shell nanocomposite of polyaniline and silica via oxidation of aniline hydrochloride by FeCl3.6H2O

“…In commercial applications PANI has been used as chemical sensors, batteries, supercapacitors, corrosion‐prevention coatings, antistatic coatings, and energy storage . A wide range of alkyl and alkoxy substituted PANI have been synthesized to improve the solubility in organic solvents and improve the potential applications compared with PANI . Similarly, composites as an interesting class of materials combine the advantages of two or more components to achieve the improved physical properties and new potential usages .…”

“…), metals (Au, Ni, Ag, etc. ), and clays have been applied in building block of PANI to require the desired mechanical, electrical, and chemical properties in the final composites and nanocomposites . However, among the numerous composites based on reviewed inorganic fillers, silica/PANI composites have attracted great academic interest because silica not only improve the mechanical and thermal properties of composite but also exhibit some interesting properties.…”
