“…A common technique to improve dispersion and achieve optimum utilization of CNTs is through chemical functionalization, which enables chemical bonding between the CNTs and material of interest. Both covalent6–10 and noncovalent11–15 functionalization methods have been employed to impart solubility and chemical modifications to CNTs. Generally, the linkage of small or large molecules to CNTs by covalent methods is more stable and effective because grafted molecules raise the solubility of CNTs even with a low degree of functionalization 16–19.…”

The nanohybrids composed of silver nanoparticles and aromatic polyamide functionalized multiwalled carbon nanotubes (MWCNTs) is successfully synthesized and tested for their antibacterial activity against different pathogens. Prior to deposition of silver nanoparticles, acid treated MWCNTs (MWCNTs-COOH) were successively reacted with p-phenylenediamine and methylmethacrylate to form series of NH 2 -terminated aromatic polyamide dendrimers on the surface of MWCNTs through Michael addition and amidation. Existence of high abundance of amine groups on the surface of functionalized MWCNTs (f-MWCNTs) provided sites for formation of silver nanoparticles by the reduction of aqueous solution of AgNO 3 . The silver nanoparticles formed in the resulted f-MWCNTs-Ag nanohybrids were determined to be face centered cubic (fcc) symmetry. The structure and nature of f-MWCNTs and f-MWCNTs-Ag nanohybrids were characterized by UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction analysis (XRD), Raman spectroscopy and thermogravimetric analysis (TGA). The dispersion state of f-MWCNTs and immobilization of silver nanoparticles on the surface of f-MWCNTs were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Elemental composition of f-MWCNTs-Ag nanohybrids was determined by energy dispersive X-ray spectroscopy (EDS). The antimicrobial activity of fMWCNTs-Ag nanohybrids were estimated against E. coli, P. aeruginosa and S. aureu and compared with MWCNTs-COOH and f-MWCNTs. The results indicate that functionalization of MWCNTs with aromatic polyamide dendrimers and successive deposition of Ag nanoparticles could play an important role in the enhancement of antimicrobial activity.

“…Also, the process normally involves van der Waals, π-π or CH-π interactions between polymer molecules and CNT surface [42][43][44] . The two major approaches for non-covalent functionalization is polymer wrapping and surfactant-assisted dispersion.…”

Carbon nanotube buckypaper reinforced polymer composites: a review

et al. 2017

RbstractThis review provides valuable information about the general characteristics, processing conditions and physical properties of carbon nanotube buckypaper (BP) and its polymer composites. Vacuum filtration is the most common technique used for manufacturing BP, since the carbon nanotubes are dispersed in aqueous solution with the aid of surfactant. Previous works have reported that mechanical properties of BP prepared by vacuum filtration technique are relatively weak. On the other hand, the incorporation of polymer materials in those nanostructures revealed a significant improvement in their mechanical behavior, since the impregnation between matrix and BP is optimized. Electrical conductivity of BP/polymer composites can reach values as high as 2000 S/m, which are several orders of magnitude greater than traditional CNT/polymer composites. Also, BP can improve remarkably the thermal stability of polymer matrices, opening new perspectives to use this material in fire retardant applications.

“…On the other hand, Morishita et al (2010) employed N-substituted MI polymers as compatibilizers for multiwalled carbon nanotube (MWCNT)-reinforced PPS composites. These aromatic polyimides exhibit very high heat resistance and can be easily synthesized by radical polymerization of MI units, which are much cheaper monomers than conventional CNT dispersants such as pyrene-containing polymers.…”
