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

摘要

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 center dot 6H(2)O 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 center dot 6H(2)O as oxidant. By increasing the concentration of monomer more uniform spheres were obtained. Characterization was made via FT-IR, UV-Vis, H-1 and C-13-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.
