20.500.12556/RUL-149338 Visokoporozni pretočni funkcionalni polimeri Highly porous flowable functional polymers Za diplomsko delo sem sintetiziral poliHIPE polimere, to so visokoporozni polimeri, ki sem jih naredil s fotoiniciirano radikalsko polimerizacijo HIPE emulzije. HIPE emulzije so emulzije, ki morajo vsebovati vsaj 74,05 volumskih % notranje faze. Z modifikacijo recepture lahko sintetiziramo poliHIPE z različnimi poroznostmi, sam sem sintetiziral 80 % poliHIPE. Same polimere lahko modificiramo tudi po polimerizaciji, da dosežemo lastnosti, ki so primerne željeni uporabi, jaz sem jih modificiral z nanocelulozo. Sintetizirane poliHIPE sem testiral na HPLC sistemu, da sem se prepričal, kateri vzorci so primerni za nadaljnjo modifikacijo z nanocelulozo. Po nalaganju nanoceluloze na vzorce, sem jih še enkrat testiral na HPLC sistemu in meril tudi pH prehode, ter primerjal rezultate s predhodnimi meritvami. S pomočjo meritev sem preučeval, če se nanoceluloza na poliHIPE sploh veže, ter ali pride do adsorpcije oziroma kemijske vezave in ne zgolj do delne zamašitve por. I synthesized polyHIPE polymers for my bacherol’s thesis, which are highly porous polymers made through photoinitiated radical polymerization of HIPE emulsion. HIPE emulsions are emulsions that must contain at least 74,05 % by volume of the internal phase. By modifying the recipe, we can synthesize polyHIPE with different porosities. I synthesized 80 % polyHIPE. The polymers themselves can also be modified after polymerization to achieve properties for desired applications. I modified them with nanocellulose. I tested the synthesized polyHIPE using HPLC system to determine which samples are suitable for further modification with nanocellulose. After loading nanocellulose onto the samples, I tested them again using HPLC system, including pH transitions, comparing the results with previous measurements. Through these analyses, I wanted to evaluate whether nanocellulose binds to polyHIPE and if the binding is chemical or adsorption and not just partial blockage of pores. poliHIPE nanoceluloza HPLC polyHIPE nanocellulose HPLC true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-09-06 12:50:00 2023-09-06 12:50:02 2023-10-11 12:41:14 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 22954 167954947 Kucis_Niko_-_Visokoporozni_pretocni_funkcionalni_polimeri.pdf Kucis_Niko_-_Visokoporozni_pretocni_funkcionalni_polimeri.pdf 1 924C9A7F30C237F7226814BA487127DE 00ee97cc53be712f2611dd55ccaf9bac107382abe71e6b10fb5acb9b5f731200 21e491c8-4ca3-11ee-9934-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173773 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
