Polymer Grafting of Carbon Nanotubes Using Living Free‐Radical Polymerization

The chemistry of carbon nanotubes has become an area of intense research as chemical derivatization is the only means for modifying the properties of these highly interesting and technologically promising materials. Specifically, numerous researchers have focused on improving the solubility of carbon nanotubes through chemical grafting. To this end, significant recent effort has been devoted to the attachment of polymers to the nanotube surface, as macromolecules can be more effective in modifying nanotube solubility properties than small molecules. In addition, the use of functional polymers has enabled the preparation of polymer-nanotube composite materials that demonstrate a variety of interesting properties, such as responsiveness to environmental stimuli (solvent, temperature, pH), the ability to complex metal ions, and photoinduced electron transport. A variety of different techniques have now been developed for the functionalization of carbon nanotubes with polymers, including "grafting to", "grafting from", and supramolecular interactions. This review will focus on recent developments in the use of living radical polymerization methods for the functionalization of carbon nanotubes with well-defined polymers.

“…Modification of the polymers physical properties as well as the implementation of new features in the polymer matrix was carried out by the addition of inorganic spherical nanoparticles to polymers. Over the past two decades, materials and structures with geometric dimensions of less than 100 nm (nanomaterial) have gained more attraction for chemistry and pharmaceuticals, such as synthesis of organic compounds, health, medical, or food technology [1][2][3][4][5][6][7][8][9][10].…”

Preparation and properties evaluation of polyimide-matrix nanocomposites reinforced with glutamine functionalized multi-walled carbon nanotube

l-glutamine-grafted multi-walled carbon carboxylic acid nanotube (denoted as l-Gl-MWCNT) and polyimide-matrix l-Gl/MWCNT (l-Gl-MWCNT/ PI) were prepared by in situ polymerization and solution-blending processes. The functionalization process was one-pot, fast, and simple, and resulted in a high degree of functionalization as well as dispersibility in organic solvents. The resulting materials were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction, high-resolution transmission electron microscopy, and field-emission scanning electron microscopy. According to the microscopic characterizations, the MWCNTs are homogeneously dispersed in the composites. The thermal stability of the films containing Gl-MWCNTs was improved as the nanotube content increased from 5 to 15 wt% due to the improved interfacial interaction between the PI matrix and surface-modified MWCNTs.

“…In the phenomenon of “free radical addition” technique used the polymer chain radicals which reacted with CC bonds of the MWCNT were produced by three main approaches; in situ radical polymerization of the monomers in the presence of the MWCNT initiated by an initiator, γ‐ray irradiation, and thermo‐initiation . In previous research, MWCNT underwent pretreatment for functional group attachment such as COOH, OH, NH 2 , prior to covalent attachment of the polymer moieties . This was the case until Wu and Liu reported a 15.6% weight grafted polystyrene on the surface of untreated MWCNT using the free radical addition process in the presence of a styrene monomer and 0.05g of 2,2′‐azobisisobutyronitrile (AIBN) initiator…”

Multiwalled carbon nanotube was successfully grafted with poly(methyl methacrylate) by free radical mechanism using benzoyl peroxide initiator. The reaction was carried out in situ, where the initiator and methyl methacrylate monomer generated the polymer-free radical that was subsequently grafted to the surface of the pristine multiwalled carbon nanotube. The multiwalled carbon nanotube grafted poly(methyl methacrylate) (MWCNT-g-PMMA) were characterized using Fourier transform infrared, differential scanning calorimetry, thermogravimetric analysis, 13 C-solid NMR spectroscopy, X-ray photoelectron spectroscopy, and scan electron microscopy. From the result of the characterizations, the grafting of poly(methyl methacrylate) on to multiwalled carbon nanotube was confirmed, and a percentage grafting of 41.51% weight was achieved under optimized conditions with respect to the temperature and the amount of the initiator.
