Abstract

Skupina keteholov je bila obsežno raziskana za razvoj hidrogelov zaradi optimalne adhezije z vodo. Čeprav je razvoj hidrogelov močno napredoval, je še vedno prostor za nadaljnje raziskave. V diplomskem delu sem se ukvarjal z povzemanjem priprave in opisa različnih hidrogelov na osnovi kompleksa iz katehol-kovinskega iona ter opisal njihove sposobnosti samoceljenja. V uvodu sem predstavil osnovne koncepte pametnih hidrogelov. V nadaljevanju sem se osredotočil na tipe vezi, ki sodelujejo pri samoceljenju hidrogela. Nato sem opisal na splošno sam katehol in razne tipe kovinskih ionov, čemur je sledil še opis interakcij hidrogelov na osnovi katehol-kovinskega iona. Temu pa na koncu sledi še podroben opis treh konkretnih hidrogelov na osnovi katehol-kovinskega iona. Te prej omenjeni hidrogeli so hidrogel na osnovi Železov (III) ion-Dopamin-Poliakrilne kisline, Hidrogel na osnovi 4-členskega polietilen glikol-Dopamin-Železovega (III) iona in Hidrogel na osnovi Železov (III) ion-Dopamin-Hialuronske kislina.

Secondary title: Self-healing hydrogels based on catechol−metal ion
Secondary abstract: The cetechol group has been extensively studied for the development of hydrogels due to their optimal adhesion to water. Although the development of hydrogels has advanced considerably, there is still room for further research. In my thesis I have worked on summarising the preparation and characterisation of various hydrogels based on the catechol-metal ion complex and describing their self-healing abilities. In the introduction I described the basic concepts of smart hydrogels. I then focused on the types of bonds involved in hydrogel self-healing. I then described the catechol itself in general and the different types of metal ions, followed by a description of the interactions of catechol-metal ion based hydrogels. This is followed by a detailed description of three specific catechol-metal ion hydrogels. The aforementioned hydrogels are dopamine-iron(III) ion-polyacrylic acid, 4-armed polyethylene glycol–dopamine–ion(III) ion and dopamine-iron(III) ion-hyaluronic acid.
