Green extract Capsicum Annuum var Annuum, was used as a reducing agent in
the synthesis of silver nanoparticles (AgNPs). The reduction kinetics was
followed by UV-visible and Fourier-transform infrared spectroscopy (FTIR),
confirming the formation and growth of AgNPs by the increase of the band
intensity of the surface plasmon resonance (SPR) characteristic in silver
nanoparticles around 460 nm. The characteristic infrared band of the amine
around 3295 nm decreased as the reaction proceeded and the spectra show
slight changes indicating the consumption of the initial components of the
extract as the reaction progressed. Photocurable acrylic resin and AgNPs were
combined in different concentrations to measure their kinetics of curing and
opto-thermal properties by means the photothermal technics. Additional
complementary analyzes for the elucidation of shape, size, crystal structure and
composition of the nanoresins such as transmission electron microscopy (TEM),
scanning electron microscopy (SEM) and X-ray spectroscopy. This study is the
initial step of a research conducted for the kinetic study of nanocomposites to
improve its characteristics to be used in prosthetic parts.
