New Hybrid Nanomaterial Based on two Polymers (PANI and PEO) in the Interlayer Galleries of an Ecologic and Friendly Catalyst Layered Called Maghnite-H+ (Algerian MMT)

摘要

Soluble and conducting block copolymer (PANI-PEO) nanocomposite was prepared by oxidative polymerization of aniline in non acid media and in different weight percentages in the presence of ecologic catalyst layered called (Maghnite-H+) and reactive polymer stabilizer such as poly(ethylene oxide) (PEO2000, Mn = 2000).The morphology, structure, solubility and electrical properties of PANI-PEO copolymer nanocomposite was characterized by FTIR,Uv-vis,1H-NMR spectroscopy , dynamic scanning calorimetry (DSC), and thermogravimetric analysis (TGA).It was found that structue, solubility an conductivity of resulting PANI-PEO nanocomposite depended on the amount of catalyst, molecular weight and functionality of the reactive stabilizer (PEO) and molar ratio of monomers (PANI-PEO). The formation of the hydrogen bonding between PANI and PEO copolymer was predicted by the FT-IR spectra. DSC analysis showed only one (Tg=16°C) for the blend copolymer implying compatibility of the two components.
