Molecular structure of PANI and its homologue PANI–PEO2000 catalyzed by Maghnite-H+ (Algerian MMT): synthesis, characterization and physical and chemical properties

Abstract

The homopolymer (PANI) and its homologue PANI-PEO 2000 copolymer have been prepared under effect of Maghnite-H+ (Algerian MMT) in different weight percentages (wt%) by cationic polymerization method. The formation of the hydrogen bonding between PANI and PEO 2000 and structure of PANI are predicted by the FT-IR and 1HNMR spectra. Glass transition temperature of pure PANI and pure PEO 2000 are, respectively, T g = 74 °C and T g = 65 °C, but DSC analysis for the copolymer (PANI-PEO 2000) showed only one (T g = 16.79 °C) implying compatibility of PANI and PEO 2000. Here we can suggest that under suitable condition (the amount of catalyst, molecular weight and functionality of the reactive stabilizer (PEO 2000) and molar ratio of (PANI/PEO 2000), our catalyst can improve the morphology, structure and chemical properties of PANI and its homologue PANI-PEO 2000 .
