Abstract

In different weight percentages of our ecological and green catalyst called Magnite-H+ (Algerian MMT) and a reactive polymer stabilizer such as poly (ethylene oxide) (PEO, Mn = 2000), the chemical transformation of polyaniline under effect of this green catalyst was investigated and discussed. The formation of the hydrogen bonding between PANI and PEO was predicted by the FT-IR and the 1HNMR spectra. The glass transition temperature of pure PANI and pure PEO respectivly (Tg=74°C and Tg= -65°C), in the other hand the DSC analysis showed only one (Tg=16.79°C) for the mixte product (PANI-PEO) implying compatibility of two components. Here we can suggest, that under suitable condition (the amount of catalyst, molecular weight and functionality of the reactive stabilizer (PEO) and molar ratio of PANI-PEO), our catalyst can improved the morphology, structure, stability and properties chemicals of polyaniline.
