Abstract
ABSTRACTPoly(m-phenylenediamine-co-anthranilic acid) P(mPDA-co-ANTH) and their doped Mn, Ni, and Cu poly (m-phenylenediamine-co-anthranilic acid) have been synthesized and characterized. Mn P(mPDA-co- AA) has been used as a molecular precursor of MnO nanoparticles. The spectral, optical, refractive index, solubility and thermal properties of the synthesized polymers have been measured and discussed. The optical band gap (Eg) measurements indicated that Mn P(mPDA-co-AA) has wider optical band than the neat P(mPDA-co-AA). MnO nanoparticles have been synthesized from calcination of MnP(mPDA-co-AA) at 800oC. The obtained nanoparticles have been characterized by XRD and HR-TEM. The average size of MnO nanoparticles was found to be 71 nm. The refractive index measurements indicated slight change in the refractive index values of the polymer solution than that of the pure solvent. The solubility of the synthesized polymers in ethanol, dimethyl formamide (DMF)-aqueous mixed solvents was found to increase as the mole fractions of both ethanol and DMF increases. UV spectra of the synthesized polymers in ethanol, DMF-aqueous mixed solvents indicated blue shift and hyperchromic effect.
