Abstract:
Tekstilni materiali, naravni (celuloza) ali sintetični (polimerni materiali) so večinoma električno neprevodni in ne omogočajo prostega pretoka električnega naboja po svoji strukturi. Posledično to povzroča kopičenje elektrostatičnega naboja na površini tekstilnega materiala, ki nastaja zaradi trenja med neprevodnimi vlakni. Statična elektrika in tveganje elektrostatičnega preboja, predstavlja problem v tekstilnih procesih in končnih aplikacijah. Cilj raziskovalne naloge je pripraviti električno prevodne sol-gel nanose na osnovi tetraetoksisilana (TEOS) in metiltrietoksisilana (Me-TREOS) a) s prevodnim tetratiafulvalenom (TTF) in b) dopirane s kovinskimi prahi: aluminij (Al), baker (Cu) in železo (Fe). S prevodnimi sol-gel nanosi se bodo modificirala naravna in sintetična tekstilna vlakna. Sol-gel nanose in modificirana vlakna bodo okarakterizirana (SEM mikroskopija, meritve električne prevodnosti in električne upornosti). Drugi del cilja raziskovalne naloge je pripraviti nanokompozite na osnovi poliamida (PA6), ki bo dopira s prevodnimi nanomateriali polianilina PANI, Ag/PANI, s prevodnim titanovim dioksidom (TiO2) in Mn acetatom ter s kombinacijami PANI, TiO2 in Mn acetat. Površinsko bodo obdelana sintetična vlakna s prevodnim nanomaterialom TiO2/Mn acetat. PA6 nanokompozite in prevodne nanomateriale materiale ter modificirana vlakna bodo okarakterizirana (FTIR, TEM, DSC, BET, meritve električne upornosti).

Title:
Preparation and characterisation of electrically conductive textile coatings
Abstract:
Textile fibres, natural (cellulose) or synthetic (polymeric materials) are generally electrically non-conductive and does not allow the free movement of electrical charge in its structure. Consequently, this results in the accumulation of electrostatic charge on the surface of the textile material, which is produced due to friction between the non-conductive fibers. Static electricity and the risk of electrostatic penetration is a problem in the textile processes and final applications. Aim of the study is to produce an electrically conductive sol-gel coatings based on tetraethoxysilane (TEOS) and methyltrietoksisilane (Me-TriEOS) a) with a conductive tetratiafulvalene (TTF), and b) doped with a metal powder: aluminum (Al), copper (Cu), and iron (Fe). Natural and synthetic textile fibers will be modified with conductive sol-gel coatings. Characterisation of coatings and modified fibres will be made (SEM microscopy electrical conductivity and electrical resistance measurements). The prepartaion of nanocomposites based on polyamide (PA6) by doping with conductive polyaniline, conductive titanium dioxide (TiO2) and manganese acetate and their combinations is the second part of the research work. Prepared conductive nanomateril TiO2 / Mn and modifide fibres acetate will be characterized (FTIR, TEM, DSC, BET, measurements of electrical resistivity).
