摘要
The critical behavior of pseudobinary microemulsion systems{water/sodium di(2-ethylhexyl)sulfo- succinate(AOT)/n-decane}with various droplet sizes was studied by measurements of refractive index. It was found that the critical exponentsβfor all systems approach 0.327 in a region sufficiently close to the critical temperature,which is consistent with 3D-Ising universality class.The critical temperatures linearly decrease as the dispersed droplet sizes increase.The critical amplitude almost linearly in- creases with increasing the dispersed droplet sizes.
The critical behavior of pseudobinary microemulsion systems {water/sodium di(2-ethylhexyl) sulfo- succinate (AOT)/n-decane} with various droplet sizes was studied by measurements of refractive index. It was found that the critical exponents ,6 for all systems approach 0.327 in a region sufficiently close to the critical temperature, which is consistent with 3D-Ising universality class. The critical temperatures linearly decrease as the dispersed droplet sizes increase. The critical amplitude almost linearly increases with increasing the dispersed droplet sizes.
