Influence of the Methodology Applied in the Formation Process of VOx / Polyaniline Nanocomposites / Influência da Metodologia Aplicada no Processo de Formação de Nanocompósito VOx / Polianilina

The present work discusses the synthesis, characterization and thermoanalytical investigation of the hybrid material based on c-V2O5 and substituted polyanilines. 50 mL of an aqueous suspension with 0.5 g of oxide (2.75 mmol) in three concentrations of 2-methylaniline and 2-propylaniline (1.07 mmol, 5.49 mmol and 10.97 mmol) was prepared and submitted to high intensity pulse ultrasound. The goal was the investigation of the effect of the organic component used to modify the physical-chemical properties of the c-V2O5 by using TG-DTA, DSC, FTIR, DRX and SEM measurements. The results showed a higher degree of intercalation process for Poly (2-propylaniline) as well as a larger basal distance for same hybrid material.
