Visokoporozni pretočni funkcionalni polimeri

Kučiš, Niko (author), Podgornik, Aleš (mentor)

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.

Abstract

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.
