| Abstract: | This research reported a CO2-switchable nanoemulsion that was formulated by dilution of water in oil microemulsion, which was formed by mixture of N,N-dimethyl oleoaminde-propylamine (DOAPA), sodium dodecyl sulphate (SDS), n-hexane, n-butanol, and water. A reversible switch process was observed between a monophasic nanoemulsion and complete phase separation at R = 1:1 with the CO2 and N2 bubbling alternately. The phase separation was not found, but the reversible switch between single phase nanoemulsion was detected by zeta potential, electrical conductivity, and dynamic light scattering at R = 1:1.5 and 1.5:1. |
