Preparation and Characterization of Composites Based on Ethylene Vinyl Acetate/Novel Aditivum
Original language description
The present study deals with the preparation and characterization of ethylene vinyl acetate materials containing fillers enriched with commercially available essential oils obtained by hydrodistillation extraction process from Carum carvi L. Two blends based on ethylene vinyl acetate, talc or bentonite with two type of extracts were prepared. The composition of essential oils extracted from fruits of caraway and the influence of two types of mineral fillers on the incorporation of caraway extracts was studied by gas chromatography mass spectrometry and gas chromatography mass spectrometry equipped with pyrolysis unit, respectively. The measurement of antibacterial activity of incorporated extracts after thermoplastic processing was determined by standard ISO 22196:2007 - Plastics: Measurement of antibacterial activity on plastics and other non-porous surfaces. The materials prepared on twin-screw micro-extruder exhibit good homogeneity throughout the all sample volume and smooth surfaces. Results of essential oil compositions dissolved into acetone show that one extract contains only carvone. On the other hand, the second one includes carvone, limonene and trace amount of beta-myrcene. Gas chromatography spectra of pyrolysed composites confirm successful incorporation of both types of the essential oils and their stability in the mineral fillers after thermal incorporation into the polymer matrix. All types of prepared antibacterial materials exhibit a high effect on Staphylococcus aureus grown reduction.
