Variation of long periodicity in blends of styrene butadiene, styrene copolymer/polyaniline using small angle X-ray scattering data

Abstract: Small angle X-ray scattering data have been recorded for the blends of styrene butadiene, styrene copolymer/polyaniline using the beamline of the LNLS (Laboratorio Nacional de Luz sincroton-Campinas, Brazil). Employing one-dimensional Hosemann's paracrystalline model, we have simulated the meridional reflections of these blends in order to compute the long periodicity and hence to find the variation with concentrations of the blends. Within the region of available experimental data we observe that there is a l… Show more

“…Each one of these different states of oxidation/protonation produces electrical conducting and color changes in the material . These changes in PAni's physical properties are being exploited to the manufacture of qualitative and quantitative sensors . These sensors respond selectively to a particular analyte, through a chemical reaction, such as oxidation or doping reactions …”

“…Other authors followed a similar approach, mostly using polyaniline doped with different types of sulfonic acid. In each case, the applications were different, e.g., adhesives, carriers for thermoplastics, corrosion protection, etc . Despite all these research efforts, these elastomers were electrically conductive only, achieving electrical conductivity values of around 10 −5 S/m.…”

“…Most of the literature found on conductive elastomers was based on polyaniline, since it is less expensive than other alternatives . However, polyaniline has several disadvantages.…”

“…Além disso, a PAni possui grande potencial para aplicações de ponta, tais como eletrodos em baterias [11] , na microeletrônica [12] , como materiais eletrocrômicos usados em visores [13] , em sensores [14][15][16] , como blindagem eletromagnética [17] , entre outras. Assim, a modificação das fibras de coco é vantajosa sob uma série de aspectos, entre os quais estão o incentivo a um maior aproveitamento destas fibras naturais, além da transferência das atrativas propriedades elétricas [18][19][20][21][22][23][24] da polianilina para a fibra, que poderia ser utilizada em diversos tipos de sensores, como os de pressão, extensão e até quimiométricos. Isto tudo, com o uso de quantidades mínimas de polianilina na forma de um nano-recobrimento condutor.…”
