“…Also, the NH stretching of amide group at 3434 cm − 1 and the NH bending of amide group at 1625 cm − 1 can be observed. Moreover, the CH stretching band at 2929 cm −1 and its bending band at 690 cm −1 arise from the aniline aromatic ring, which confirm the successful amidation reaction on the surface of CNTs …”

The preparation of thermoplastic nanocomposites of waterborne polyurethane (WBPU) and multiwall carbon nanotubes (MWCNTs) via an in situ polymerization approach is presented. The effects of the presence and content of MWCNTs on the morphology and thermal, mechanical and electrical properties of the nanocomposites were investigated. Carbon nanotubes were modified with amide groups in order to enhance their chemical affinity towards WBPU. Thermogravimetric studies show enhanced thermal stability of the nanocomposites. Scanning and transmission electronic microscopy images prove that functionalized carbon nanotubes can be effectively dispersed in WBPU matrix. Mechanical properties reveal that Young's modulus and tensile strength tend to increase when appropriate amounts of MWCNTs are loaded due to the reinforcing effect of the functionalized carbon nanotubes. Thermal properties show an increase in the glass transition temperature and storage modulus with an increase in MWCNT content. X‐ray diffraction reveals better crystallization of the WBPU in the presence of MWCNTs. The WBPU/MWCNT nanocomposite film containing 1 wt% of MWCNTs exhibits a conductivity nearly five orders of magnitude higher than that of WBPU film. © 2017 Society of Chemical Industry

“…After, the chemically modified material was dried in a low pressured-oven, at 120 C. This process is necessary, since in composite applications there is a need to disperse the MWCNTs homogeneously throughout the polymeric matrix. The acid treatment was used in order to minimize the aggregation of the particles and improve the dispersion behavior, since the MWCNTs have a hydrophobic surface that is prone to aggregation and precipitation [36,37].…”

The production of polymeric fibers by the electrospinning technique stands out as being simple, accessible, versatile and with potential use of polymer microfibers in many areas of science and technology. In this article, polymeric microfibers of PBAT/PLA and carbon nanotubes were obtained using a Fractional Factorial Design. The statistical results, the optical microscopy and scanning electron microscopy (SEM) showed that the addition of MWCNT's had an influence in the diameter of the fibers (1.16 ± 0.22 mm), so that its incorporation decreased the value of the diameter, also they were more uniform and homogeneous. Besides, the MWCNT's provided the fibers a better mechanical resistance, probably being inside the fibers, as well as showed in the analysis of wettability by contact angle.
