Title : Silver nanoparticles in zeolites matrix incorporated in commercial coating

Abstract:

In this report, results about the incorporation of silver nanoparticles in coatings are shown. The results were obtained using clinoptilolite-stilbite, clinoptilolite, and chabazite natural zeolites. The ion exchange properties of the zeolite promoted the obtaining and stabilization of the nanoparticles. The particle size of 2-20 nm was determined by TEM microscopy. Absorption bands around 400 nm were detected and associated with surface plasmon resonance. The bactericidal efficiency of the coatings was evaluated after incorporated on surfaces against Gram-positive and Gram-negative bacteria. The results indicated a higher bactericidal effect than the positive control.
