Cilji in kompetence:
Objectives and competences:

Študentje spoznajo osnove o površinskih lastnostih organskih materialov, ki so odvisne predvsem od vrste in koncentracije funkcionalnih skupin na površini teh materialov. Spoznajo metode za modificiranje površine organskih materialov in postopke plazemske funkcionalizacije teh materialov z različnimi funkcionalnimi skupinami, kot so dušikove (amino, amidna), kisikove (hidroksilna, karbonilna, karboksilna) in halogene.

Seznanijo se tudi z metodami za karakterizacijo funkcionalnih skupin na površini organskih materialov in metodami za merjenje hidrofilnosti/hidrofobnosti teh materialov.

Na koncu se študentje seznanijo še s praktičnimi primeri uporabe plazme za površinsko modifikacijo organskih materialov na primeru aplikacij iz različnih panog (industrija, biologija, medicina…).

Students gain knowledge on surface properties of organic materials, which depend predominantly on the type and concentration of functional groups on the surface of these materials. They get knowledge on modification of the surface of organic materials and methods for plasma functionalization with different functional groups such as nitrogen (amino, amide), oxygen (hydroxyl, carbonyl, carboxyl) and halogen.

Students also get knowledge on methods for characterization of functional groups on the surface of organic materials and measuring hydrophilicity/hydrophobicity of these materials.

Finally, the students gain knowledge on applications of plasma surface modification of organic materials in the case of various practical applications (industry, biology, medicine ...).
