-
The effect of hydrate formation/dissociation on W/O emulsions stabilized using solid particles of varying hydrophobicity was investigated.
-
W/O emulsions stabilized with moderately hydrophobic particles resisted destabilization due to hydrate formation/dissociation.
-
W/O emulsions stabilized using surfactant or highly hydrophobic particles exhibited destabilization due to hydrate formation/dissociation.
-
Residual droplet size of surfactant stabilized emulsions increased after hydrate formation/dissociation unlike solid stabilized emulsions.
-
Presence of solid particles at the liquid-liquid interface did not modify the IFT value significantly unlike surfactants.
