On their own, the titania particles attached strongly to the oil–water interface and stabilised emulsions, while the silica particles did not attach to the interface. Adding silica particles to the titania dispersions enhanced coalescence processes during emulsion formation, except under mixing conditions that favoured particle heteroaggregation.The destabilisation of the emulsions was linked to the presence of silica particles in the particle layersat the interface.enCopyright 2009 Elsevierpickering emulsionsnanoparticle stabiliserbinary particle mixturecoalescenceheteroaggregationJournal article10.1016/j.jcis.2009.10.068000273665900029
