Abstract

Pripravili smo olje-v-vodi (O/V) emulzije z visokim deležem notranje faze, kjer so monomeri raztopljeni v vodni fazi. Oljno fazo smo pripravili z mešanjem različnih organskih topil, pri čemer smo k toluenu dodali različno volumsko razmerje metanola, izopropil alkohola, dioksana oz. tetrahidrofurana. Kinetično stabilne emulzije smo s prosto radikalsko polimerizacijo nato polimerizirali v hidrofilne porozne monolite na osnovi akrilamida ali 2-hidroksietil metakrilata, zamrežene z N,N'-metilen bisakrilamidom. Raziskali smo vpliv dodatka topil na samo stabilnost emulzij ter na morfologijo končnih monolitnih nosilcev, skupno površino in velikost ter obliko por.

Secondary title: An effect of organic solvents on the morphology of emulsion templated porous polymers
Secondary abstract: Hydrophilic porous monoliths based on acrylamide and 2-hydroxyethyl methacrylate crosslinked with N,N'-methylene bisacrylamide were obtained by free radical polymerization of the continuous phase of oil-in-water high internal phase emulsions (HIPEs). The influence of solvent addition on emulsion stability and polymer morphology (surface area, porosity, pore size) was investigated.
