研究目的
To study the polymerization of aniline and its homologue block copolymer PANI–PEO catalyzed by Maghnite-H+ as proton exchanged montmorillonite clay under microwave irradiation.
研究成果
The study successfully demonstrated the synthesis of PANI and PANI–PEO2000 composites using Maghnite-H+ as an ecological catalyst. The composites showed improved morphology, structure, and chemical properties under optimized conditions. The findings suggest potential applications in conducting polymers and nanocomposites.
研究不足
The study focuses on the synthesis and characterization of PANI and PANI–PEO2000 composites using Maghnite-H+ as a catalyst. The limitations include the specific conditions under which the polymerization was carried out (microwave irradiation at 160°C) and the use of a particular type of clay (Algerian MMT).
1：Experimental Design and Method Selection:
The study involved the preparation of PANI and PANI–PEO2000 copolymer under the effect of Maghnite-H+ (Algerian MMT) by cationic polymerization method. The formation of hydrogen bonding and structure were analyzed using FT-IR and 1HNMR spectra.
2：Sample Selection and Data Sources:
Polyethylene oxide (PEO2000) was obtained from Sigma Aldrich, and MMT clay was obtained from ENOF Maghnia (Algeria).
3：List of Experimental Equipment and Materials:
Microwave apparatus (CEM reactor, Model Discover), 300 MHz Bruker NMR spectrometer, ATI Matson FT-IR, Ubbelohde capillary viscosimeter, WISP 712 Waters Associates chromatograph.
4：Experimental Procedures and Operational Workflow:
The polymerization was carried out under microwave irradiation at 160°C. The products were characterized by various spectroscopic and thermal analysis techniques.
5：Data Analysis Methods:
The data were analyzed using FT-IR, 1HNMR, UV–visible spectroscopy, TGA, DSC, and GPC.
