Definitions
- the present invention relates to a method for biofunctionalization of textile materials which leads to obtaining antibacterial and antifungal properties.
- the structure of the coatings was examined by X-ray diffraction (XRD) method and by UV-Vis spectroscopy and HIRBS.
- the obtained coatings showed high antibacterial activity against Escherichia coli strains which was increasing together with the increase of metal concentration, and decreasing with the increase of heat treatment temperature during the process of forming Cu nanoparticles.
- the most effective antimicrobial properties were exhibited by the coatings which were not thermally treated under an oxidizing or reducing atmosphere.
- SiO 2 nanoparticles served as a substrate for the continuous deposition of copper.
- the chemical structure and morphology of the nanocomposite was examined by the X-ray photoelectron spectroscopy (XPS) method, scanning electron microscopy combined with energy-dispersive X-ray spectroscopy (SEM-EDX) and transmission electron microscopy (TEM).
- XPS X-ray photoelectron spectroscopy
- SEM-EDX energy-dispersive X-ray spectroscopy
- TEM transmission electron microscopy
- the copper nanoparticles homogeneously formed on the surface of SiO 2 nanoparticles did not undergo aggregation and exhibited excellent antibacterial activity with respect to multiple microorganisms.
- AAS atomic absorption spectroscopy
- Nanosilica which was modified on the surface with copper particles was used to remove the odor of mercaptans and sulfur compounds from petroleum. According to the publication in Langmuir, vol. 26, 15837-15844 (2010 ), silica modified by the addition of copper also exhibited antibacterial properties.
- Copper silicate is used in medicine and biology, for instance, in controlled release of drugs and thermal treatment of tumors.
- An additional advantage of copper silicate CuO - SiO 2 is the possibility to modify its surface and properties using hydrophobic substances, simple chemical processes and organofunctional compounds [ Bioelectrochemistry, vol. 87, 50-57 (2012 )].
- the publication in the Nanoscale Research Letters journal, vol. 6, 594-602 (2011 ) reveals that cotton textiles impregnated with silica sol containing 0.5 - 2 % by weight of copper nanoparticles, having dried exhibited excellent antibacterial properties against both gram-negative and gram-positive bacteria.
- the AMB Express magazine, vol. 3, 53 (2013 ) publishes an article describing very good antimicrobial properties of nanocomposites Cu-SiO 2 , obtained in the form of thin layers using the CVD method, against multiple hospital pathogens ( Acinetobacter baumannii, Klebsiella pneumoniae, Stenotrophomonas maltophilia, Enterococcus faecium, Staphylococcus aureus and Pseudomonas aeruginosa ).
- the SEM method confirmed the nanostructure of Cu particles in the silica matrix.
- the tested shells of nanocomposites Cu-SiO 2 can also be used for microbial protection of metal and ceramic surfaces.
- the invention relates to a method for biofunctionalization of textile materials using copper silicate in the hydrate form, which is premixed with the polymer component, a plasticizer and an antioxidant, then the whole is heated until the polymer melts, and then the molten composition is subjected to pneumothermal extrusion and blowing the molten polymer in a stream of hot air.
- Copper silicate hydrate is used in an amount of 0.1 - 4 % by weight.
- polymers selected from the group consisting of polypropylene (PP) and its copolymers, polylactide (PLA), polyhydroxyalkanoate (PHA), polyethylene (PE) and / or mixtures thereof are used as polymer components.

- Plasticizers are used in an amount of 1.5 - 15 % by weight in relation to the mass of polymer or the mass of polymer mixture, preferably 2.5 - 5 % by weight.
- an antioxidant 2,2'-Methylenebis(6-tert-butyl-4-methylphenol) (MBMTBP) or 2,2'-Methylenebis(6-tert-butyl-4-ethylphenol) (MBETBP) to the component system was applied.
