JIMENEZ-RODRIGUEZ, José Alfredo; ARANA-SOSA, Vanesa y FRANCO, Alfredo. Síntesis de nanotubos de carbono multicapa sobre sustratos metálicos por el método de depósito químico de vapores: no todos los nanotubos son iguales. Mundo nano [online]. 2017, vol.10, n.19, pp.93-108. Epub 21-Ago-2020. ISSN 2448-5691. https://doi.org/10.22201/ceiich.24485691e.2017.19.57211.
In this work, we report a new way to grow carbon nanotubes on micro-crystals. The micro-crystals are deposited on thermo-chemically treated metallic substrates, they are used as a substrate for the growth of carbon nanotubes with novel structural shapes. These new nanotubes shapes are: double spiral assembled bundles and flower-shaped assembled carbon nanotubes. These are new multiwalled carbon nanotubes (MWCNT’s) morphological shapes, which are synthesized by means of the chemical vapor deposition (CVD) technique. These new shapes are very attractive for the potential use of MWCNT’s in several technological applications. This paper describes, in a clear way, what are carbon nanotubes, which are the most common methods used to synthesize them and which are the new kinds of MWCNT’s synthesized in the Jumex. Nanotechnology Lab, in collaboration with researchers from other institutions.
