Resumo
This study consists in the characterization of polyamide (PA6) films charged with different concentrations of silver nanoparticles deposited in titanium dioxide (TiO2) carrier. The silver nanoparticles were synthesized according to the method adapted from Turkevich using a titanium dioxide carrier and inserted, by suspension, in a polyamide solution. The preparation of PA: AgNp films was performed by the casting method by the dissolution of PA pellets in formic acid.
The analysis and characterization of the films by the XRD, DSC, TGA and Raman confocal techniques indicated incorporation of nanoparticles into the polymers, a second thermogravimetric decomposition event as the concentration of AgNp-TiO2 increased and there was no significant change in crystallinity.
