Abstract:Naraščajoča skrb za zdravje in spremembe v življenjskem standardu so povečale zanimanje za razvoj protimikrobnih tekstilij, ki preprečujejo rast mikroorganizmov in delujejo preventivno proti okužbam, kot so okužbe kože in sluznic. Hitozan, naravni biopolimer, pridobljen iz hitina, se je izkazal za učinkovito protimikrobno sredstvo, saj preprečuje rast bakterij in gliv z vezavo na njihove celične stene ter zaviranjem njihovega metabolizma. Diplomsko delo obravnava vpliv plazemske obdelave celuloznih vlaken na njihovo sposobnost adsorpcije hitozana. V raziskavi smo del celuloznih vlaken obdelali s plazmo, medtem ko smo preostali del pustili neobdelan. Obe vrsti vzorcev smo nato analizirali, da bi ocenili morebitno povečanje reaktivnosti in sposobnosti vezave hitozana kot posledico plazemske obdelave v primerjavi z neobdelanimi vlakni. Cilj raziskave je bil ugotoviti, ali plazemska obdelava vpliva na izboljšanje adsorpcijskih lastnosti celuloznih vlaken. Za oceno učinkovitosti postopka smo uporablili naslednje metode: potenciometrična titracija za določanje vezave hitozana, UV-Vis analiza za merjenje koncentracije preostalega hitozana, merjenje togosti ploskih tekstilij za oceno uporabnih lastnosti obdelanih vlaken ter merjenje protimikrobnosti. Rezultati so pokazali, da plazemska obdelava bistveno izboljša adsorpcijo hitozana na celulozo. Plazemska obdelava se je izkazala kot obetavna metoda za funkcionalizacijo tekstilij, ki omogoča ustvarjanje okolju prijaznih in učinkovitih zaščitnih materialov. Diplomska naloga s svojimi ugotovitvami prispeva k napredku na področju razvoja tekstilij z dodano vrednostjo in odpira nove možnosti za raziskave v tej smeri.

Title:Plasma-Activated adsorption of chitosan on cellulose
Abstract:Growing health concerns and changes in living standards have increased interest in the development of antimicrobial textiles that prevent the growth of micro-organisms and act as a preventive against infections such as skin and mucous membrane infections. Chitosan, a natural biopolymer derived from chitin, has proven to be an effective antimicrobial agent, preventing the growth of bacteria and fungi by binding to their cell walls and inhibiting their metabolism. The thesis deals with the effect of plasma treatment of cellulose fibres on their ability to adsorb chitosan. In this study, part of the cellulose fibres was treated with plasma, while the rest was left untreated. Both types of samples were then analysed to assess the possible increase in reactivity and chitosan binding capacity as a result of plasma treatment compared to untreated fibres. The aim of the study was to determine whether plasma treatment has an effect on improving the adsorption properties of cellulose fibres. The following methods were used to assess the effectiveness of the process: potentiometric titration to determine chitosan binding, UV-Vis analysis to measure the concentration of residual chitosan, stiffness measurement of flat textiles to assess the usable properties of the treated fibres, and antimicrobiality measurement. The results showed that plasma treatment significantly improves the adsorption of chitosan on cellulose. Plasma treatment has proven to be a promising method for the functionalisation of textiles, allowing the creation of environmentally friendly and effective protective materials. The thesis contributes with its findings to the advancement of the development of value-added textiles and opens new avenues for research in this direction.
