diplomsko delo
Abstract
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.

Highly porous flowable functional polymers |
Secondary 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. |
