20.500.12556/RUL-149011 Površinska energija in omočljivost materialov za pripravo hrane The surface energy and wettability of materials for food preparation V okviru zaključne naloge smo proučevali interakcije med različnimi tekočinami in materiali, ki se pogosto uporabljajo v kuhinjskih pripomočkih. S pomočjo analiz površinske energije, omočljivosti in topografije smo podrobno raziskali ključne lastnosti teh materialov. Posebej smo se osredotočili na različne lastnosti, kot sta hidrofobnost in hidrofilnost, ki sta bili najbolj izraziti pri teflonski prevleki in emajlu. Jeklo je pokazalo enakomerno omočljivost z oljem in vodo, plastika pa se je bolj omočila z vodo. Topografska analiza je potrdila, da topografija površine materialov, kot sta gladkost emajlirane prevleke in hrapavost keramike, močno vpliva na njihovo omočljivost. Naše ugotovitve prinašajo vpogled v optimizacijo materialov za uporabo v kuhinjskih pripomočkih in odpirajo možnosti za nadaljnje raziskave s ciljem izboljšanja industrijskih aplikacij. In this work interactions between various liquids and materials commonly used in kitchen utensils were examined. Analyzing surface energy, wettability, and topography, we thoroughly investigated the key properties of these materials. We particularly focused on distinct properties, such as hydrophobicity and hydrophilicity, which were most pronounced in the Teflon coating and enamel. Steel demonstrated uniform wettability with both oil and water, whereas plastic showed a better wettability with water. The topographic analysis confirmed that the surface structure of materials, like the smoothness of the enameled coating and the roughness of ceramics, significantly influences their wettability. Our findings offer insights into the optimization of materials for kitchen appliances and open up opportunities for further research aimed at enhancing industrial applications. površinska energija omočljivost površin kot omočljivosti dinamična omočljivost histereza kontaktnega kota topografija površine surface energy surface wettability contact angle dynamic wetting contact angle hysteresis surface topography true false false [T.
