Percolation in alkyl polyglycoside microemulsions

摘要: Mixtures of oil, water, alkyl polyglycosides and long-chain alcohols form almost-temperature-invariant microemulsions. The phase behaviour depends on the content cosurfactant, usually alcohols. We show that system C8/10G1.5/octane/water/octanol exhibits cosurfactant-induced percolation phenomena. transition from an electrically conducting oil-in-water microemulsion to non-conducting water-in-oil with increasing cosurfactant is observed by measurements electrical conductivity time-resolved electric birefringence. field-off relaxation time yields information internal length scale. scaling times Kerr constants respect point leads insight into influence behaviour.
