Highly crystalline and thermally stable poly(aniline-co-2-nitroaniline)
Waware, Umesh S.; Rashid, Mohd; Hamouda, A. M.S.; Adnan, Rohana ( Springer Nature , 2020 , Article)Abstract: To synthesize a crystalline polymer is unconventional. Here, we found the well-defined hexagonal or rectangular cubical shape of poly(aniline-co-2-nitroaniline)s PA-co-2-NAs through scanning electron microscopy. ... -
N-cetyl-N,N,N trimethyl ammonium bromide (CTAB)-stabilized polyaniline: a corrosion inhibitor for mild steel
Rashid, Mohd; Waware, Umesh S.; A. Rahim, Afidah; Hamouda, A. M.S. ( Emerald Publishing , 2018 , Article)Purpose: The purpose of this study is to compare the inhibitive effect of polyaniline (PAni) and N-cetyl-N,N,N trimethyl ammonium bromide (CTAB)-stabilized PAni in a hydrochloric acid (HCl) medium. Design/methodology/approach: ... -
Poly(aniline-co-o-nitroaniline): transport properties using electrochemical impedance spectroscopy
Waware, Umesh S.; Rashid, Mohd; Summers, G. J.; Hamouda, A. M.S.; Adnan, Rohana ( Springer Science and Business Media Deutschland GmbH , 2020 , Article)Highly uniform ac conductivity and dielectric permittivity of poly(aniline-co–o-nitroaniline) (PA-co-o-NA)s have been recorded by using electrochemical impedance spectroscopy in the frequency range of 10–2–107 Hz. Also, ... -
Synthesis and characterization of electroactive novel poly-2-cynoaniline
Waware, Umesh S.; Rashid, Mohd; Rahim, Afidah A.; Umare, S. S. ( Indian Academy of Sciences , 2014 , Article)Uniform needle-like structures of poly-2-cynoaniline are formed without the use of any template by electrochemical oxidative polymerization method on copper electrode in acidic medium. The structural characterizations are ...
