Abstract

Diplomsko delo prikazuje študijo Schiffove bazne kondenzacije med substituiranim tereftaldehidom in 1,4-fenildiaminom za pripravo poliHIPE materialov na osnovi poliazometinov. Π-konjugirane poliHIPE pene smo pripravili s polimerizacijo emulzij z visokim deležem notranje faze (HIP emulzije). Sintetizirane polimere smo očistili s Soxhlet ekstrakcijo z metanolom. Uspešnost organo-katalizirane sinteze poliazometinov smo preverili s spektroskopskimi tehnikami kot so FTIR analiza, UV-Vis DRS analiza in 13C CP/MAS NMR spektroskopijo v trdnem. Morfološke lastnosti smo preverili z vrstično elektronsko mikroskopijo (SEM). S He-piknometrijo smo določili gostoto in določili poroznost polimera. Informacije o porazdelitvi por in specifični površini smo dobili z dušikovo fizisorpcijo.

Secondary title:	Synthesis of pi-conjugated polymer foams by various condensation reactions
Secondary abstract:	The thesis aimed to study the Schiff base condensation reaction between substituted terephthalaldehyde and 1,4-diphenylamine to prepare poly(azomethine)-based polyHIPE foams. Π-conjugated polyHIPE foams were prepared by polymerization of high-internal phase emulsions (HIPE) templates. The synthesised polymer foams were purified by Soxhlet extraction with methanol. The successful synthesis of poly(azomethine) based foams was further analysed by spectroscopic techniques such as FTIR analysis, DR UV/Vis analysis and solid-state 13C CP/MAS NMR spectroscopy. The morphological properties were checked by scanning electron microscopy (SEM). The density and porosity of the polymer were determined by He pycnometry. The pore distribution and specific surface area were determined by nitrogen physisorption.
