Filme autosuportado de polianilina desdopada para aplicações anticorrosivas

Abstract: Resumo: Os polímeros intrinsecamente condutores (PIC), como a polianilina (PAni), têm sido estudados com alternativa em filmes protetores de metais oxidáveis contra a corrosão. Dada a dificuldade de fusão ou dissolução da PAni para a produção de filmes, investigou-se a possibilidade de obter filmes pela mistura de PAni no estado oxidado e desdopado, conhecida como base esmeraldina, com plastificante não dopante 4-cloro-3-metilfenol (CMF) e solvente conveniente. Filmes produzidos desta forma foram caracterizado… Show more

“…Among tested materials, the one modified with PAni ES presented the lowest electrical resistivity value. In turn, the other materials presented higher electrical resistivity values, as described in the literature . Again, these confirm the well‐succeeded modification of the fabric with different oxidation stats of PAni.…”

“…These components were submitted to intense agitation with the aid of high speed disperser Dispermat Model N1, in bottle closed for a period of 2 h, with the aim of dispersing and homogenizing the mixture of PAni EB and CMP contained in the binder (Silva et al, 2012).…”

“…(Baldissera et al, 2012). Conform Silva et al (2012), is promising the use of PAni on state oxidized and nonconductive, known as emeraldine base polyaniline (PAni EB) because this ICP presents a low electronic conductivity and or ionic in relation to PAni EP, which represents a low diffusion of ions, and assists the barrier effect produced by the coating constituted of PAni EB. Furthermore, the PAni EB has the ability to form free-standing resins, ie, films with sufficient cohesion and homogeneity to the application in a metallic surface.…”

“…de diferentes métodos, como auto suportado (casting) [6,7] , automontagem (layer by layer) [8] e in situ [9][10][11] . Entretanto, as propriedades elétricas dos filmes de PAni dependem do seu processamento e podem sofrer alterações quando em contato com eletrodos metálicos [12] .…”
