| Description
| - Organically modified vermiculite (NaVER/CA) was used as nanofiller for preparation of vermiculite-chlorhexidine/polyethylene nanocomposites (NaVER/CA-PE). Organovermiculte was prepared from sodium vermiculite (NaVER) and chlorhexidine diacetate (CA) through the process of intercalation. The set of vermiculite-chlorhexidine/polyethylene nanocomposites was prepared from mixtures containing polyethylene (PE) and clay nanofiller NaVER/CA (weight ratios of clay nanofiller : PE were 3:37, 6:34, 10:30). The mixtures were melt-compounded using a Brabender twin-screw extruder and the plate samples of NaVER/CA-PE nanocomposites were pressed for antimicrobial tests. The structural characteristics of the nanocomposites were studied by X-ray diffraction, infrared spectroscopy and optical microscopy. The antimicrobial activity was studied against Gram–negative Escherichia coli and Gram–positive Staphylococcus aureus using microbial fingerprints technique with blood agar. The first fingerprints of samples were made after 24 h, next after 48, 72 and 96 h. The results of antibacterial tests show good antimicrobial effect depending upon time of contact of colony–forming units of bacteria with the surface of plates. The most intensive degradation of number of bacteria was between 48 and 72 h.
