Special Issue Information

Dear Colleagues,

Carbon-based nanomaterials are rapidly emerging as one of the most fascinating materials in the twenty-first century. Carbon is a very important element in the periodic table that essentially forms the basis of life on Earth. Soon after the discovery of 0D fullerene, the synthetic carbon family was graced by the addition of quasi-1D carbon nanotubes (CNTs), of which discovery in 1991 created a boom in the scientific world. CNTs based materials are expected to possess additional interesting electronic, mechanical, and molecular properties. The prime advantages of the CNTs include high surface-area-to-volume ratio and unique thermal, optical, mechanical, and electrical properties to name a few.Thus, given the immense advantages of CNTs, this Special Issue focuses on the different aspects of CNTs and their applications. This Special Issue of C Journal of Carbon Research invites innovative contributions in terms of research articles, reviews, communications, and letters from around the globe. Potential topics include, but are not limited to, structure and chemistry of carbon nanotubes; characterization; functionalization; and applications, including polymer nanocomposites.

Silica microtube and carbon nanotube hybrid structures have been synthesized by catalytic chemical vapor deposition using either methane or ethene as the carbon source, and cobalt-grafted or impregnated silica tubes (200–800 nm) as catalyst. The cobalt-grafted catalyst shows a high resistance to reduction (>1000 °C) and selectivity to single-wall carbon nanotubes (SWCNT). While ethene deposition produces more carbonaceous material, methane experiments show higher selectivity for SWCNT. After removing the silica with an excess of HF, the carbon nanostructure endured, resulting in a coaxial carbon nanostructure. The novel hybrid nanostructures obtained consist of a submicron-sized tube, with walls that are formed by a succession of carbon/silica/carbon layers to which multiwall (20–25 nm) and/or single-wall (0.6–2.0 nm) carbon nanotubes are attached. This synthesis approach combines the mechanical properties of carbon nanotubes and the thermal properties of silica tubes into a synergetic nanostructured material, opening further possibilities for polymer reinforcement and potential applications in catalysis.

In order to develop a novel technique for the fabrication of hybrid materials containing polymers and nanocarbons, we examined the surface modification of pristine multi-walled carbon nanotubes (MWCNTs) with benzyl-type polymer side chain radicals generated through photolysis of 4-(chloromethyl)benzoate moieties. The polymer with a 4-(chloromethyl)benzoate side chain was prepared by the esterification of polyvinyl alcohol (PVA) with corresponding acid chloride. The synthesized polymer and MWCNTs were mixed in N-methylpyrrolidone and irradiated with ultraviolet (UV) light. Structural changes of the polymer and MWCNTs were observed by means of X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The XPS results revealed that scission of the C–Cl bonds of the chloromethyl groups and benzyl-type radical formation occurred. The incremental surface defects of the MWCNTs caused by UV irradiation were confirmed by means of Raman spectroscopy. These results support the covalent bond formation between the polymer side chain and MWCNT sidewalls by radical addition reaction. The photothermal conversion characteristics of the prepared materials were also evaluated. Full article
