Characterization of Poly(o-methoxyaniline) Emeraldine-base form obtained at different time neutralization

Rigid and semi rigid polyurethane resins: A structural investigation using DMA, SAXS and Le Bail method

“…Nevertheless it has been used to characterize some polymeric materials [16][17][18][19][20]. In order to be able to estimate R factors related to integrated intensities, Rietveld [21] stated: ''a fair approximation to the observed integrated intensity can be made by separating the peaks according to the calculated values of the integrated intensities, i.e.…”

Nanostructured Polypyrrole Powder: A Structural and Morphological Characterization

“…[47,48] to obtain structural information from semicrystalline patterns is not very common due to the large overlapped peaks on diffractograms. Nevertheless, it has been used to characterize some conducting polymers as polyaniline and substituted polyanilines [49][50][51]. This process uses iteratively the Rietveld decomposition formula for whole powder pattern decomposition (WPPD) in the FullProf program package [52].…”

Chemically synthesized poly(o-methoxyaniline): Influence of counterions on the structural and electrical properties

“…Previous reports based on PANI and its derivatives also verified average crystallite size smaller than 55 Å [5,80,81]. The HCl-doped POMA was previously synthesized [5] The as-synthesized polymers presented a prolate-like crystallite shape.…”

“…For this reason, the functionalized side groups at the ortho, meta or para positions in polyaniline (PANI) derivatives, such as poly(o-methoxyaniline) -POMA, allowed a range of physicochemical properties [3]. Structural, morphological, thermal and electrical properties of ortho-substituted polyanilines have been widely discussed [4][5][6]. However, to the best of our knowledge, no systematic studies have been reported on the relationship between the influence of doping acids on the properties of POMA.…”
