In this paper, we have prepared high internal phase Pickering emulsions (Pickering HIPEs) with internal phase volume fraction 90% which are stabilized by a mixture of silica nanoparticles (H30) and poly(L-lactide-co-glycolide) (PLGA). HIPEs with an internal phase volume not more than 75% could be prepared solely by H30 nanoparticles. Using PLGA as stabilizer, phase separation takes place and stable emulsions are not formed. Synergistic interaction between H30 particles and PLGA molecules plays an important part in preparation of HIPEs. Using inorganic particles and polymer as co-stabilizer will be a new and effective method to prepare HIPEs.

Key words: high internal phase emulsion, Pickering emulsion, H30 nanoparticle, PLGA, synergistic effect
