20.500.12556/DKUM-93608 Sinteza eugenol metakrilata in njegova uporaba pri razvoju funkcionalnih polimernih mrež diplomsko delo univerzitetnega študijskega programa I. stopnje Synthesis of eugenol methacrylate and its application in the development of functional polymer networks V tej diplomski nalogi smo se osredotočili na razvoj in karakterizacijo polimernih materialov, pripravljenih iz eugenol metakrilata (EMA), ki smo ga sintetizirali iz eugenola z esterifikacijo z anhidridom metakrilne kisline. Na ta način smo pridobili monomer z visoko reaktivno metakrilatno funkcionalno skupino. Strukturo in čistost EMA smo potrdili z uporabo naprednih analitskih tehnik, kot sta jedrska magnetna resonanca (NMR) in Fourierjeva transformacijska infrardeča spektroskopija (FTIR). Nato smo pripravili porozne polimerne materiale z dvema metodama: polimerizacijo v masi in polimerizacijo zunanje faze emulzije z visokim deležem notranje faze (t. i. HIP emulzije). V obeh primerih smo kot monomer uporabili EMA, kot zamreževalo pa etilen glikol dimetakrilat (EGDMA). Polimerizacijo v masi smo izvedli z uporabo različnih topil (toluen, etanol, metanol in propan-2-ol), da bi preučili vpliv topila na morfologijo nastalih materialov ter na sposobnost polimerizacije eugenol metakrilata. Eugenol kljub prisotnosti proste vinilne skupine v svoji strukturi sam po sebi ni zmožen polimerizacije, medtem ko metakrilatna skupina v EMA izkazuje visoko reaktivnost, kar smo tudi eksperimentalno potrdili. S polimerizacijo HIP emulzij smo želeli sintetizirati materiale z večjo poroznostjo in specifično površino, kar smo tudi uspešno dosegli. Sintetizirani materiali so izkazovali tipično poliHIPE strukturo z večjimi primarnimi in manjšimi sekundarnimi porami. Pridobljene polimerne materiale smo karakterizirali z vrstično elektronsko mikroskopijo (SEM), FTIR spektroskopijo, elementno analizo in porozimetrijo, da bi ocenili njihovo morfologijo, kemijsko sestavo ter strukturne lastnosti. In this thesis we have focused on the development and characterisation of polymeric materials prepared from eugenol methacrylate (EMA) synthesised from eugenol by esterification with methacrylic anhydride. In this way, we have obtained a monomer that has a highly reactive methacrylate functional group. The structure and purity of EMA were confirmed using advanced analytical techniques such as nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FTIR). Subsequently, porous polymeric materials were produced using two methods: bulk polymerisation and polymerisation of the outer phase of a high internal phase emulsion (so-called HIP emulsion). In both cases, EMA was used as the monomer, while ethylene glycol dimethacrylate (EGDMA) served as the crosslinker. Bulk polymerisation was carried out with different solvents (toluene, ethanol, methanol and isopropanol) to investigate the influence of the solvent on the morphology of the resulting materials and on the polymerisability of eugenol methacrylate. Although eugenol contains a free vinyl group in its structure, it is not able to polymerise by itself, whereas the methacrylate group in EMA has a high reactivity, which was confirmed experimentally. With the polymerisation of HIP emulsions, we aimed to synthesise materials with higher porosity and specific surface area, which we succeeded in doing. The synthesised materials exhibited a typical polyHIPE structure characterised by larger primary and smaller secondary pores. The obtained polymeric materials were characterised by scanning electron microscopy (SEM), FTIR spectroscopy, elemental analysis and porosimetry to evaluate their morphology, chemical composition and structural properties. porozni polimeri HIP emulzija poliHIPE eugenol metakrilat bio-osnovan polimer porous polymers HIP emulsion poliHIPE eugenol methacrylate biobased polymer true true false [V.
