20.500.12556/RUL-160171 Priprava visoko poroznih poliHIPE nosilcev različnih prepustnosti Preparation of highly porous polyHIPE scaffolds of different permeability PoliHIPE materiali so visoko porozni polimeri različnih oblik, sintetizirani iz HIPE emulzij. Posebnost teh emulzij je visoka vsebnost notranje faze, ki je vsaj 74 %. To polimeru omogoča različne prednosti in dobre lastnosti ter možnosti modifikacije, posledično pa tudi uporabo na številnih področjih, kot so tkivno inženirstvo, separacijske tehnike in mnoge specialne aplikacije. Cilj diplomske naloge je bil uspešno sintetizirati poliHIPE vzorce z različnimi poroznostmi, in sicer 75, 80, 85 in 90 %. Pripravljenim vzorcem smo nato na HPLC sistemu preverili homogenost strukture in padec tlaka ter izračunali njihove prepustnosti. Izbrana sinteza poliHIPE vzorcev se je izkazala za uspešno, dokaj enostavno in ponovljivo. Pridobljeni rezultati so pokazali linearno zvezo med poroznostjo in prepustnostjo. PolyHIPE materials are highly porous polymers of various shapes, synthesized from HIPE emulsions. A distinctive feature of these emulsions is the high content of the internal phase, which is at least 74%. This gives the polymer various advantages, favorable properties and possibilities for modification, leading to applications in many fields, such as tissue engineering, separation techniques and many special applications. The thesis aimed to successfully synthesize polyHIPE samples with different porosities, namely 75, 80, 85, and 90%. The prepared samples were then checked on the HPLC system for homogeneity of the structure and pressure drop, to determine their permeability. The selected synthesis of polyHIPE samples was successful, relatively simple and reproducible. The results obtained showed a linear relationship between porosity and permeability.
