Uniform Macroporous Ceramics and Plastics by Emulsion Templating *
Macroporous materials with uniform pore sizes in the range from 50 nm to 10 mm are predicted to have unique and highly useful properties as optical devices, specifically for use as photonic crystals with optical bandgaps. Moreover, the ability to control pore size and uniformity could produce improved filters, membrane supports, catalytic materials, and adsorbents. Nevertheless, until very rece...
متن کاملHighly permeable macroporous polymers synthesized from pickering medium and high internal phase emulsion templates.
Effect of additives on the pore structure of polymer foams obtained from Pickering HIPE templates Various routes were investigated to create pore throats in closed-celled poly-Pickering-HIPEs; we tried to dissolve the silica particles used as emulsifiers out of the thin films separating individual pores by adding NaOH into the aqueous phase, which resulted indeed in the formation of interconnec...
متن کاملCovalent incorporation of the surfactant into high internal phase emulsion templated polymeric foams.
High internal phase emulsions of water in cyclooctene stabilised by sorbitan monooleate (Span 80) were cured by ring-opening metathesis polymerisation to release fully open macroporous polymer foams wherein the surfactant was covalently incorporated into the poly(cyclooctene) strands via chain transfer reactions.
متن کاملCombining plasmachemical emulsion-templating with ATRP to create macroporous lipophilic surfaces.
Well-defined alkyl chain side group polymer brushes have been tethered onto high surface area macroporous pulsed plasmachemical emulsion-templated poly(vinylbenzyl chloride) initiator layers (typically 600-700 m2 g(-1)) using atom transfer radical polymerisation (ATRP). Immobilisation of phospholipids onto these bioactive surfaces is found to occur through interdigitation, and the efficacy of l...
متن کاملLignin-based Pickering HIPEs for macroporous foams and their enhanced adsorption of copper(II) ions.
Interconnected macroporous foams were synthesized by templating oil-in-water Pickering high internal phase emulsions solely stabilized by lignin particles. They exhibited excellent adsorption capacity for copper(II) ions in aqueous solutions.
