عنوان انگلیسی Synthesis and Characterization of Phenylene Diamine and Poly (Methyl Methacrylate) Coupled with Multi-Walled Carbon Nanotubes by in Situ Oxidation Polymerization
چکیده انگلیسی مقاله In this study, an effective approach for the preparation of functionalized multi-wall carbon nanotubes (MWCNTs) through grafting with PDA (phenylenediamine) and PMMA (polymethyl methacrylate) by in situ oxidation polymerization method was demonstrated successfully. To this purpose, first, the carboxylated MWNCTs (MWNCTs–COOH) after treatment with pristine MWCNTs were obtained with a compound of 3:1 (v/v) HNO3 and H2SO4. Then, MCNTs-CO-NH-Ph by treated MWCNTs-COOH with aniline, DCC, and DMAP were produced. Following that, the ring of aniline was nitrated by means H2SO4 and HNO3. To synthesize MCNTs-PDA, the nitro group was reduced to the amine group with HCl in ethanol. Finally, MWCNTs-PDA was functionalized by in situ oxidation polymerization with PMMA to afford MWCNTs-g-(PDA-g-PMMA). The resulting functionalized MWCNTs (Oxidation, decrease, and coupling) were demonstrated by FT-IR spectroscopy, and morphology attachment of PDA and PMMA onto MWCNTs surfaces was confirmed by SEM, TEM, and AFM. Thermal particularities of grafted polymers onto MWCNTs surfaces were studied using TGA and DSC analysis. The prepared MWCNTs-g-(PDA-g-PMMA) can be used as an improvement for polymeric (nano-) composites owing to the excellent properties of MWCNTs in addition to their adaptability with polymeric materials after functionalization processes.
