Abstract
The present invention relates to active and intelligent additives having hybrid characteristics, that are compatible with polymers, are thermally and mechanically stable, are capable of releasing electrons and/or photons in the presence of chemical compounds, specifically amino compounds, amide compounds, oxygen reducing compounds, water or vapors thereof. The active and intelligent additives incorporate themselves into polymer matrices allowing the obtainment of active and intelligent polymeric articles. These active and intelligent polymeric articles may act as inhibitors of growth of microorganisms and fungi, as well as indicators of the presence of gasses, either in the atmosphere or caused by the decomposition of foodstuffs, for example.
