By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Essential Amino Acids. According to news reporting from Esfahan, Iran, by NewsRx journalists, research stated, "Carboxylic functionalized multi-walled carbon nanotubes (MWCNTs) have been incorporated to biodegradable poly(ester-imide) (PEI) matrix and the effect of the carboxylated-MWCNT on the thermal and morphological properties of MWCNT-reinforced bionanocomposites (BNCs) was demonstrated. Chiral PEI was synthesized from a step-growth polymerization of amino acid based diacid (4) with 4,4'-thiobis(2-tert-butyl-5-methylphenol) (5) promoted by tosyl chloride in pyridine and N,N-dimethyl formamide solution."

The news correspondents obtained a quote from the research from the Isfahan University of Technology, "The resulting BNCs were analyzed by Fourier transform infrared spectroscopy, Xray diffraction, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The homogeneous dispersion of MWCNTs throughout PEI matrix and strong interfacial adhesion between them were achieved in the obtained BNCs as evidenced by FE-SEM and TEM images."

According to the news reporters, the research concluded: "The results from TGA indicated that the thermal stability of the resulting BNCs was obviously improved in comparison with the pure PEI."
