Resumo: | In this work, we present the chemical synthesis of polypyrrole and polyaniline precursor materials and its hybrid material formed with magnetite polypyrrole/magnetite and polyaniline/magnetite, respectively. The synthesis of hybrids materials was performed using three different proportions of magnetite. All the materials obtained in this work were characterized by ultraviolet-visible spectroscopy (UV-VIS), X-ray diffractometry (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray fluorescence (EDXRF), Simultaneous thermogravimetric analysis TG/DTA and Cyclic Voltammetry. Precursors and hybrids were studied in a comparative way to evaluate the influence of the magnetite on the hybrid properties and estimate the best proportion of magnetite to be added in each polymer matrix. From the obtained results, it was possible to analyze the influence of the proportions of magnetite under the polymeric material in the formation of the hybrid. Regarding the pure material, the hybrids presented better properties in most of the techniques like EDXRF, X-rays, SEM. These results revealed that there was a limited amount of inorganic material for each polymer matrix, which depends on several factors, such as the magnetite particle size (in this study it was on micrometric scale) and that higher or lower amounts of inorganic phase do not present satisfactory results in relation to the potential application of these hybrid materials in electrochemical systems. The cyclic voltammetry showed a small improvement in the electrochemical behavior of the hybrid materials in relation to the precursors, showing a potential application mainly in capacitors and electrochemical sensors. |

Todos os materiais obtidos neste trabalho foram caracterizados utilizando as técnicas de espectroscopia no ultravioleta-visível (UV-VIS), difratometria de Raios X (DRX), Microscopia Eletrônica de Varredura (MEV), Fluorescência de Raios X por dispersão de Energia (EDXRF), Análise termogravimétrica simultânea TG/DTA e Voltametria Cíclica. Foram estudados precursores e híbridos de modo comparativo com o objetivo de avaliar a influência da presença da magnetita nas propriedades dos materiais e determinar qual a proporção mais indicada de magnetita a ser incorporada em cada matriz polimérica. A partir dos resultados obtidos, foi possível analisar a influência das proporções de magnetita sob o material polimérico na formação do híbrido. Em relação ao material puro, os híbridos apresentaram melhores propriedades na maioria das técnicas como EDXRF, Raios X, MEV. Os resultados revelaram que há uma quantidade ideal de material inorgânico para cada matriz polimérica, que depende de diversos fatores como o tamanho de partícula da magnetita obtido (que nesse trabalho foi em escala micrométrica) e que quantidades muito pequenas ou muito elevadas podem não apresentar resultados satisfatórios quando o objetivo é realizar aplicação desses materiais híbridos em sistemas eletroquímicos. A técnica de voltametria cíclica mostrou pequena melhora no comportamento eletroquímico dos materiais híbridos em relação aos precursores, mostrando um potencial para aplicação principalmente em capacitores e sensores eletroquímicos.Submitted by Fabiano Jucá (fjuca@unicentro.br) on 2017-06-30T18:53:37Z No. of bitstreams: 1 Caroline Zanotto.pdf: 5274521 bytes, checksum: 0f98dd1594c5ed71a6818f75d1d63bc0 (MD5)Made available in DSpace on 2017-06-30T18:53:37Z (GMT).

description |
In this work, we present the chemical synthesis of polypyrrole and polyaniline precursor materials and its hybrid material formed with magnetite polypyrrole/magnetite and polyaniline/magnetite, respectively. The synthesis of hybrids materials was performed using three different proportions of magnetite. All the materials obtained in this work were characterized by ultraviolet-visible spectroscopy (UV-VIS), X-ray diffractometry (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray fluorescence (EDXRF), Simultaneous thermogravimetric analysis TG/DTA and Cyclic Voltammetry. Precursors and hybrids were studied in a comparative way to evaluate the influence of the magnetite on the hybrid properties and estimate the best proportion of magnetite to be added in each polymer matrix. From the obtained results, it was possible to analyze the influence of the proportions of magnetite under the polymeric material in the formation of the hybrid. Regarding the pure material, the hybrids presented better properties in most of the techniques like EDXRF, X-rays, SEM. These results revealed that there was a limited amount of inorganic material for each polymer matrix, which depends on several factors, such as the magnetite particle size (in this study it was on micrometric scale) and that higher or lower amounts of inorganic phase do not present satisfactory results in relation to the potential application of these hybrid materials in electrochemical systems. The cyclic voltammetry showed a small improvement in the electrochemical behavior of the hybrid materials in relation to the precursors, showing a potential application mainly in capacitors and electrochemical sensors. |
