Study on Properties and Structural Parameters of Microemulsion CTAB/Butanol/Cyclohexane/Salt Aqueous Solution

摘要

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 ΔG*o→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 Nd decrease, Rw, l and n increase; with the increase of salt concentration, the area of microemulsion, l and Nd decrease, ΔG*o→I, Rw 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.
