ALEXANDRA PICA, ANTON FICAI A NEW GENERATION OF ANTIBACTERIAL FILM FORMING MATERIALS
In this paper we present the antibacterial performance of some modified film forming materials used for a long lifetime protection of wood, concrete, gypsum boards and other building materials. The film forming material have antibacterial properties due to the presence of AgNPs in their composition. The structure and morphology of the antibacterial coatings were determined by scanning electron microscopy (SEM) and XRF. The introduction of 100-200ppm AgNPs in AMFF produces an optimum improvement in the antibacterial resistance. It has been shown that the new film forming material (AMFF) does not deteriorate even if subjected to 200 cycles of wet rubbing. AMFF shows antibacterial efficacy on the bacteria (gram-negative and gram-positive) after 200 washing cycles.
