The effect of the viscosity on the production of alumina borate nanofibers was investigated and the optimum parameters were determined to obtain the best fibers. DTA/TG analyses were performed to determine the heat-treatment regime. The morphology of the fibers was evaluated by SEM analyses, the phase structure of the fibers was obtained using XRD and the chemical bonding structure was determined by FTIR. On the whole, the results indicated that the viscosity of a solution is an important parameter for producing a homogeneous and thin fiber, while the calcination temperature has a significant effect on the phasestructure of the fibersAluminijevooksidnoboratna (Al18B4O33) nanovlakna so bila uspešno izdelana z elektrospining metodo z uporabo raztopine, ki vsebuje polivinil alkohol (PVA) in aluminijev acetat, stabiliziran z borovo kislino. Preiskovan je bil vpliv viskoznosti na izdelavo aluminijevooksidnoboratnih nanovlaken in določeni so bili optimalni parametri za pridobivanje najboljših vlaken. Za določitev režima toplotne obdelave so bile izvršene DTA/TG-analize. Morfologija vlaken je bila ocenjena s SEM-analizo, fazna struktura vlaken je bila dobljena z rentgensko difrakcijo (XRD), strukture kemijskih vezav pa so bile ugotovljene s FTIR. Rezultati so pokazali, da je viskoznost raztopine pomemben parameter za proizvodnjo homogenih in tankih vlaken, medtem ko ima temperatura kalcinacije pomemben vpliv na strukturo faz vlakenTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
