Study on properties and structural parameters of microemulsion CTAB/butanol/cyclohexane/salt aqueous solution

The phase diagrams of microemulsion CTAB/butanol/cyclohexane/aqueous solution of nitrate (or aqueous solution of ammonium salt) were determined and the structural parameters and Delta G*(0 -> i) were obtained by means of dilution method and theoretical calculation. The effect of different w/s and salt concentration on the stability and structural parameters of microemulsion were investigated. The result shows that with the increase of w/s, the area of microemulsion and N-d decrease, R-w, l and a increase; with the increase of salt concentration, the area of microemulsion, l and Nd decrease, Delta G*(0 -> 1), R-w and n increase. Theoretical basis of preparing size-controlled long afterglow luminescence materials and study of the relationship between fluorescence properties and particle size are provided.
