Stable water and glycerol marbles immersed in organic liquids: From liquid marbles to Pickering-like emulsions
2012
Bormashenko, Edward | Pogreb, Roman | Musin, Albina
Water and glycerol marbles coated with various powders and immersed in organic liquids gave rise to water-in-oil and glycerol-in-oil Pickering-like emulsions. Non-polar oils such as polydimethylsiloxane, toluene, xylenes and chlorinated solvents supported the formation of emulsions, whereas polar liquids such as dimethylsulfoxide, N,N,-dimethylformamide, acetone and ethanol did not. It is demonstrated that there is a direct contact between a liquid filling the immersed marble and the surrounding liquid. A phenomenological theory of the marbles’ sinking into emulsion is proposed.
