Resumo: | The nanotechnology has been focused of many studies and become scientifically and technologically revolutionary. It can be found in many products on the market. The nanoscale is defined as a billionth of a meter (10-9m). The manipulation in this scale has provided a series of studies in the health, computing, physics, chemistry, materials and others fields. In the context of manipulation of nanostructures, this paper proposes an alternative produtcion of NTC on arc discharge method, which dispense the use of sealed cameras and working with water as an insulator environment. The project was divided in two main stages: the software development and the production of NTC. A control system via software to manage the approach speed of the electrode (cathode) and the speed of rotation of electrode (anode) was developed in the first stage. In the second stage, tests were performed with different parameters for the production of NTC: source type (direct current and alternating current), type of catalyst, solubilized iron in the water and iron doped in the anode electrode, and also two types of graphite called A and B (higher purity). The material produced was characterized by the Raman Spectroscopy and Scanning Electron Microscopy techniques. Carbon nanotubes were produced when the graphite with higher purity was used, independently of the type of catalyst and the source used. In addition to the CNT was possible to observe with graphite B the production of several carbon nanostructures as nanosphere, nanorods, nanohoneycombs and nanoflowers of grapheme. However the graphite A (low purity) produced microspheres and nanospheres. |

A nanoescala é definida como a bilionésima parte do metro (10-9m). A manipulação nesta ordem de grandeza despertou uma serie de estudos nas áreas de saúde, computação, física, química, materiais, entre outras. Dentro do contexto de manipulação de nanoestruturas o presente trabalho propõe um método alternativo de produção de nanotubos de carbono por arco elétrico, o qual dispensa a utilização de câmeras seladas, trabalhando com água como meio isolante. O Trabalho foi divido em duas etapas principais: o desenvolvimento do software e a produção de NTC. Na primeira etapa foi desenvolvido um sistema de controle via software para gerenciar a velocidade de aproximação do eletrodo (cátodo) e a velocidade de giro do eletrodo (ânodo). Na segunda etapa realizaram-se testes com diferentes parâmetros para produção de NTC: tipo de fonte (corrente continua e alternada), tipo de catalisador: ferro solubilizado em água e ferro dopado no eletrodo ânodo, além de dois tipos de grafite, denominadas A e B (grafite B com maior pureza). O material produzido foi caracterizado pelas técnicas de Espectroscopia Raman e por Microscopia Eletrônica de Varredura. Nanotubos de carbono foram produzidos quando se utilizou grafite B de alta pureza, independendo do tipo de catalisador e da fonte utilizada. Alem dos NTC foi possível observar com a grafite B a produção de diversas nanoestruturas de carbono como nanoesferas, nanorods (nanovaras), nanofavos de mel e nanoflores de grafeno. Já para a grafite A, com baixa pureza, produziu apenas microesferas e nanoesferas.Made available in DSpace on 2018-06-27T18:56:15Z (GMT).
