 Full text | Abstract: Nanotechnology offers the possibility of rendering textiles certain properties which protect humans and their natural environment. Nano-particles of metal oxides – titanium oxide (TiO2) and zinc oxide (ZnO) – belong to a group of compounds showing photocathalytic properties i.e, the ability to absorb UV radiation and antibacterial properties. The aim of this research work, carried out by the Textile Research Institute, was the development of nano-structural textile composites with barrier properties. In the firststage of the research, the morphology and micro-structure of titanium dioxide before and after modification with aminosilane were determined at the Institute of Technology and Chemical Engineering at Poznań University of Technology. Further works focused on the development of: compositions of optimal dispersion containing ZnO and TiO2 nano-particles and the methodology of nano-particle incorporation into selected textile substrates. Antibacterial properties were evaluated using the gram positive bacteria Staphylococcus aureus and the gram negative bacteria Escherichia coli. The evaluation also concerned the ability to block UV radiation by textile materials modified with nano-particles of metal oxides. The works performed proved the possibility of manufacturing a new generation of textile nano-composites with barrier properties against UV radiation and bacterial development. |
