Figure 3. Predicted radii of microemulsion droplets as a function of the volume ratios of alcohol to surfactant in microemulsions. The predictions are for a system consisting of the surfactant SDS, 1-pentanol, 0.3 M NaCl, water, and cyclohexane. The total volume fraction of the surfactant in the microemulsions is 0.01. Filled circles denote O/W droplets, and open circles correspond to W/O droplets. Figure 3.

Figure 6. Thicknesses of the interfacial layers of droplets (circles) and areas per surfactant molecule of the droplets at an oil-water interface (squares) as functions of the volume ratios of alcohol to surfactant in microemulsions for systems containing O/W (filled symbols) and W/O (open symbols) droplets. All the system characteristics are identical to those described for Figure 3. Figure 6.

The recent development of using polymerizable surfactants in microemulsion polymerizations has enabled the production of transparent sohd polymers with some nanostructure. Randomly distributed bicontinuous nanostructures of water channels and polymer domains in sohd polymers can be readily obtained from the polymerization of bicontinuous microemulsions consisting of various types of vinyl monomers and polymerizable surfactants with no allyhc hydrogen. [Pg.293]
