Lightweight Foams with Open-Cell Structure Prepared by Pickering High Internal Phase Emulsions

Abstract:

Lightweight foams with open-cell structure are prepared through water-in-oil Pickering high internal phase emulsions (HIPEs), whose density could be low down to 32.5 mg/cm³. The Pickering HIPEs are stabilized by copolymer particles, which also act as the building block for the resultant polymeric foams. The presence of toluene in the organic phase played a key role for the formation of well-defined interconnected pores in the resulting foams. The interconnectivity and the density of the foams could be tailored by varying the particle and electrolyte concentration in aqueous phase as well as the amount of toluene in the organic phase.
