“…However, the applications of CNTs in different fields have been limited by the strong intrinsic van der Waals force between the CNTs, which results in self-aggregation and the formation of the bundles or agglomerates of the nanotubes in liquid media or in polymer matrix [4]. To efficiently maintain and transfer their unique properties into different materials and actualize the potential applications using CNTs, many efforts have been focused on improving the dispersion of CNTs in solvents and the interfacial interaction of CNTs with other compounds [5,6].…”

“…Therefore, poor dispersion, the lack of solubility and weak chemical compatibility with the polymer matrix have become a bottleneck in the application of CNTs [11]. Mechanical methods such as ultrasonication and high-shear mixing as well as chemical methods including non-covalent and covalent functionalization were among the commonly used methods to prevent CNTs aggregation and achieve good dispersion in the polymer matrix.…”

Abstract.A simple and efficient method was presented for chemical functionalization of multi-walled carbon nanotubes (MWCNTs) with vitamin B 1 . Poly(ester-imide) (PEI) based nanocomposites were prepared by the incorporation of different amounts of modified MWCNTs (5, 10, 15 wt%) into a chiral and biodegradable PEI by solution blending and ultrasonic dispersion methods. The chiral PEI was produced by a step-growth polymerization of chiral diacid with 4,4!-thiobis(2-tertbutyl-5-methylphenol). Spectroscopic and microscopic techniques were used to examine the chemical structure, morphology and thermal stability of the functionalized MWCNTs and the obtained nanocomposites. The microstructure study revealed the homogeneous dispersion of modified MWCNTs throughout the PEI matrix. Thermogravimetric analysis results confirmed that the heat stability of the prepared composites was improved compared to the pure PEI.

“…Good thermal and electrical conductivity, high chemical stability, high mechanical performance, strong adsorptive ability, and excellent biocompatibility are advantageous for various applications. [1][2][3] CNTs have been broadly used in energy storage and conversion, solar cells, thermal conductors, optoelectronics, biosensors, drug delivery, and strength reinforcement in composites. [4][5][6][7] Polymer nanocomposites have attracted great attention due to the possibility to improve the composite properties for different applications in electronics, antistatic films, coatings for electrostatic painting, sporting goods, automotive parts, and reinforced aerospace materials.…”

Chemical functionalization of carboxylated multiwalled carbon nanotubes with vitamin B1 was carried out under ultrasonic irradiation. The functionalized nanotubes were embedded in a chiral and biodegradable poly(ester-imide) to prepare multiwalled carbon nanotubes reinforced polymer nanocomposites. Optically active poly(ester-imide) was synthesized by step-growth polymerization of aromatic diol and amino acid based diacid. The vitamin B1 functionalized multiwalled carbon nanotubes and the resulting nanocomposites were examined using Fourier-transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, transmission electron microscopy, and field-emission scanning electron microscopy. Thermogravimetric analysis results indicated that temperature at 10% weight loss was increased from 409℃ for pure PEI to 419℃, 427℃, and 430℃ for nanocomposites containing 5%, 10%, and 15% functionalized multiwalled carbon nanotubes, respectively. The Fourier-transform scanning electron microscopy and transmission electron microscopy images exhibited that the functionalized multiwalled carbon nanotubes were separated individually and enwrapped by polymer chains.
