Synthesis and corrosion resistance properties of novel conjugated polymer-Cu2Cl4L3 composites
A novel conjugated polyaniline (PANI)-[Cu2Cl4(m-aminophenylbenzimidazole)3] hybrid nanocomposites were prepared by using novel benzoyl peroxide as an organic oxidant by Inverse emulsion polymerization technique. The FTIR spectra of nanocomposites revealed the vibrational bands due to N–H stretching...
