New evidence for the mechanism of the pore formation in polymerising High Internal Phase Emulsions or why polyHIPEs have an interconnected pore network structure

We present new evidence that the formation of pore throats (windows) or pore interconnects in polymerised High internal Phase Emulsions (polyHIPEs) is most likely due to a mechanical action exerted during the post-synthesis processing of the porous polymer monolith. We would like to invite researchers interested in this field to reopen the discussion on the mechanism which lead to the formation of pore throats during the polymerisation of concentrated emulsion templates.
