Hobiger, Viola published the artcileEmulsion Templated Porous Poly(thiol-enes): Influence of Photopolymerisation, Emulsion Composition, and Phase Behaviour on the Porous Structure and Morphology, Application of Pentaerythritol tetra(3-mercaptopropionate), the main research area is polythiolene emulsion composition photopolymerization; bicontinuous structure; high internal phase emulsions; phase inversion; poly(thiol-enes); polyHIPE; thiol-ene polymerisation.
The 1,6-hexanediol diacrylate (HDDA) or divinyl adipate (DVA) and pentaerythritol tetrakis(3-mercaptopropionate) (TT) were polymerized via a thiol-ene radical initiated photopolymerization using emulsions with a high volume fraction of internal droplet phase and monomers in the continuous phase as precursors. The porous structure derived from the high internal phase emulsions (HIPEs) followed the precursor emulsion setup resulting in an open porous cellularly structured polymer. Changing the emulsion composition and polymerization conditions influenced the resulting morphol. structure significantly. The investigated factors influencing the polymer monolith morphol. were the emulsion phase ratio and surfactant concentration, leading to either interconnected cellular type morphol., bicontinuous porous morphol. or a hollow sphere inverted structure of the polymerized monoliths. The samples with interconnected cellular morphol. had pore diameters between 4μm and 10μm with approx. 1μm Sized interconnecting channels while samples with bicontinuous morphol. featured approx. 5μm wide pores between the polymer domains. The appropriate choice of emulsion composition enabled the preparation of highly porous poly(thiol-enes) with either polyHIPE or bicontinuous morphol. The porosities of the prepared samples followed the emulsion droplet phase share and could reach up to 88%.
