The influence of application methods (with hydrophilic PCNF or hydrophobic AP), screen perforation (60 and 135 mesh), and printing processes (single or double layer on back side or single layer on both sides) was investigated. In the first part, the effect of differently sized (20-50 nm) ATH/AMH NPs on thermal stability of MFC films was investigated. Film with 0.15 wt% addition of 20 nm AMH NP was the most thermally stable, with multi-stage decomposition starting at 305 °C, as well as 20% higher residue at 600 °C and 42% lower specific heat capacity compared to pure MFC film. In addition, the film was flexible, optically transparent (95%), hydrophobic (68°), and had a tensile strength of 69 MPa and an elastic modulus of 5.7 GPa, with low oxygen permeability (2192 cm3/m2/day). In the second part, a back side double-layer coating of 1.5 wt% PCNF and 6.7 wt% ATH NP resulted in synergistic effects, whereby the fabric retained up to 30% of high-intensity heat flux (21 kW/m2), 15 °C better thermal stability, an 11 second longer ignition time, reduced heat and smoke release (by 60% and 75% respectively), asymmetric wettability (face CA-36°, back CA-121°), with increased water vapour and heat transfer (by 17% and 22% respectively). In contrast, in addition to improved thermal protection (18 °C higher thermal stability), fabric printed with 0.4 wt% SWCNT in AP on the back side and 1.5 wt% PCNF on the front side had improved thermo-physiological comfort (25% increased heat and 17% water vapour transfer), and asymmetric wettability (CA-48° face-side, CA-129° back-side), along with high UV protection (UPF 109) without colour change, together with electrical conductivity of 4,9·10–4 S/cm, with the potential for antistatic and electro-magnetic radiation protection"},{"@xml:lang":"sl","#text":"Namen doktorske disertacije je bil preučiti učinek uporabe ekonomsko in ekološko sprejemljivejših nanodelcev Al-hidroksida (v primerjavi s SWCNT) kot zaviralcev gorenja in načina njihovega nanosa (v kombinaciji s hidrofilno PCNF ali hidrofobno AP) na izboljšanje termofizioloških, toplotnih in mehanskih lastnosti ognjevarno-zaščitne tkanine. Analizirana sta bila vpliva finosti šablone (60 in 135 mesh) in postopka tiskanja (enoslojno ali dvoslojno na hrbtni strani ali enoslojno na obeh straneh). V prvem delu disertacije je bil preučen vpliv različno velikih (20–50 nm) ATH/AMH ND na toplotno stabilnost filmov MFC. Toplotno najstabilnejši film z 0,15 ut% dodatkom 20 nm AMH ND in začetkom večstopenjske razgradnje pri 305 °C je v primerjavi s filmom iz čiste MFC imel 20 % višji ostanek pri 600 °C ter 42 % nižjo specifično toplotno kapaciteto. Prav tako je bil film prilagodljiv, optično transparenten (95 %), hidrofoben (68°), z natezno trdnostjo 69 MPa in elastičnim modulom 5,7 GPa ter nizko prepustnostjo kisika (2.192 cm3/m2/dan). V drugem delu disertacije je tkanina zaradi sinergističnih učinkov 1,5 ut% PCNF in 6,7 ut% ATH ND enostranskega dvoslojnega nanosa na hrbtni strani zadržala do 30 % visoko intenzivnega toplotnega toka (21 kW/m2), izkazala 15 °C boljšo temperaturno stabilnost, 11 s daljši čas do vžiga, zmanjšano količino sproščene toplote (za 60 %) in dima (za 75 %) ter izrazito asimetrično omočljivost (lice CA – 36°, hrbet CA – 121°) ob povečanem prenosu vodne pare (17 %) in toplote (22 %). Tkanina, tiskana z 0,4 ut% SWCNT v AP na hrbtni strani in 1,5 ut% PCNF na lični, je imela poleg izboljšane toplotne zaščite (18 °C boljša temperaturna stabilnost), termofiziološkega udobja (25 % povišan prenos toplote, 17 % vodne pare) in asimetrične omočljivosti (lice CA – 48°, hrbet CA – 129°) tudi visoko UV-zaščito (UPF 109), brez spremembe barve. Na strani z nanesenimi SWCNT je tkanina z električno prevodnostjo (4,9 · 10–4 S/cm) izkazala tudi potencial za antistatično zaščito ter zaščito pred elektromagnetnim sevanjem"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"visokošolska dela"},{"@xml:lang":"en","#text":"theses and dissertations"},{"@rdf:resource":"http://www.wikidata.org/entity/Q1266946"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-22WFRBNN","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-22WFRBNN"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-22WFRBNN/104282f0f00340-be407129-86d-98a93-eb/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Mariboru, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-22WFRBNN/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-22WFRBNN"}}}}
