20.500.12556/RUL-182317 Vpliv strukture aluminijaste superhidrofobne površine na interkacijo z vodno kapljico Effect of surface structure of superhydrophobic aluminum on the interaction with a water droplet V diplomski nalogi smo obravnavali vpliv mikrostrukture aluminijaste superhidrofobne površine na omočljivost, odboj in izhlapevanje vodne kapljice. Izdelali smo lasersko strukturirane in hidrofobizirane vzorce z različno globino ter razmikom kanalov ter analizirali njihov vpliv na izbrane parametre. Vsi vzorci so izkazovali superhidrofobnost. Učinkovitost odboja je z naraščanjem Weberjevega števila padal, maksimalni razširitveni koeficient naraščal, kontaktni čas pa se ni bistveno spreminjal. Globlji in gostejši kanali so podaljšali izhlapevanje. In this thesis, we investigated the influence of the microstructure of an aluminum superhydrophobic surface on the wetting, rebound, and evaporation of a water droplet. Laser-structured and hydrophobized samples with different channel depths and spacings were produced, and their influence on the selected parameters was analyzed. All samples exhibited superhydrophobicity. Rebound efficiency decreased with increasing Weber number, the maximum spreading coefficient increased, while the contact time did not change significantly. Deeper and denser channels prolonged evaporation. superhidrofobna površina omočenje odboj izhlapevanje učinkovitost odboja laserska obdelava superhydrophobic surface wetting rebound evaporation rebound efficiency laser processing true false false [U.
