Razvoj merilne proge za ovrednotenje hitrosti kapilarnega vleka strukturiranih površin : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programPanjan, Nejc, strojnikV zaključni nalogi smo obravnavali problem ovrednotenja interakcije superhidrofilne površine s kapljevitim medijem, saj klasična metoda merjenja kota omočenja statične kapljice, ne omogoča ustreznega ... ovrednotenja. Uporabili smo metodo ovrednotenja hitrosti kapilarnega vleka, pri kateri merimo hitrost iztekanja kapljevine iz kapilare ob stiku s površino trdne snovi. V ta namen smo razvili merilno progo in z njo izvedli meritve na različno obdelanih vzorcih. Uporabili smo bakrene ploščice in z različnimi vzorci strukturiranja izdelali superhidrofilne površine. Z merilno progo smo beležili časovno odvisnost spremembe višine kapljevine v kapilari, spreminjanje višine pa smo merili s hitro kamero. Meritve smo izvedli s cevko z notranjim premerom 0,5 mm, v kateri je bilo približno 1 µL destilirane vode. Po obdelavi posnetkov meritev smo dobili grafe premika gladine kapljevine v kapilari, iz katerih smo lahko določili hitrost kapilarnega vleka vzorca. Na bakrenih površinah smo naredili križne vzorce z različnimi razmiki med črtami in ugotovili, da so hitrosti kapilarnega vleka največje na vzorcu z najmanjšim razmikom. S povečevanjem razmika med črtami križnega vzorca, se hitrost kapilarnega vleka zmanjšuje.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [N.
