Tannin-based monoliths from emulsion-templating

摘要: Abstract Highly porous monoliths prepared by emulsion-templating, frequently called polymerised High Internal Phase Emulsions (polyHIPEs) in the literature, were from “green” precursors such as Mimosa bark extract, sunflower oil and ethoxylated castor oil. Various fractions, ranging 43 to 80 vol.%, used shown have a dramatic impact on resultant structure. A critical fraction around 70 vol.% was found exist, close theoretical values of 64% 74% for random compact sphere packing, respectively, at which properties both emulsions derived changed. Such change behaviour observed many different techniques viscosity, electron microscopy, mercury intrusion, mechanical studies. We show explain why this is one leading strongest most homogeneous monoliths.
