Abstract
Grafen velja za najtanjši, najmočnejši in najtrši material na svetu. Zaradi svojih unikatnih električnih, mehanskih in optičnih lastnosti je primeren za vgradnjo v polimerno matriko in odkrivanje novih kompozitov. Do funkcionalizacije grafena s polimerom lahko pridemo na več načinov, med drugim tudi z ultrazvokom. V sklopu magistrske naloge je bila izvedena študija vpliva ultrazvoka na funkcionalizacijo grafena s polivinil alkoholom, ki temelji na meritvah tlakov v bučki med samim procesom funkcionalizacije pod vplivom ultrazvočne kavitacije. Na podlagi tega je bila podana razlaga rezultatov kavitacijskih učinkov.

Title:Influence of the ultrasound cavitation intensity on the graphene functionalization
Abstract:
Graphene is known as thinnest, strongest and most durable material in the world. Due to its unique electrical, mechanical and optical properties, it is an ideal nanofiller for various polymers and discovering new composites. The functionalization of graphene with polymer can be achieved in several ways, including ultrasound. This study presents the influence of ultrasound on the functionalization of graphene with polyvinyl alcohol and is based on pressure measurements in the flask during the process, under the influence of ultrasonic cavitation. Based on the results, an explanation of the sonochemical effects reported in the literature is given.

Keywords:graphene, ultrasound cavitation, functionalization
