Abstract

In this paper we present the biological performance of some film-forming materials with polymer matrix of acrylic-styrene type (water soluble) obtained by synthesis in solution. The obtained coating materials have antimicrobial properties due to the presence of nanosilver in their composition. The structure and morphology of coating materials were determined by Scanning Electron Microscopy (SEM), Thermogravimetric Analysis and Differential Scanning Calorimetry (TG-DSC). The antifungal activity of the coating materials was investigated on 12 cultures of mushrooms. Based on these results it is considered that the coating materials based on nanosilver can be used to inhibit the development of micro-organisms on concrete surfaces inside the medical units..
