SDS/n－C5H11OH/n－C7H16/H2O体系中W/O－BI微乳液界面电性质

In the system of SDS/n-C5H11OH/n-C7H16/H2O with the weight ratio of SDS/n-C5H11OH/H2O system at5.0/47.5/47.5, the upper phase of the system was W/O microemulsion, and the lower phase was the bicontinuous microemulsion. When the n-heptane content was less than 1%, with the increase of the n-heptane content, the capacitance (Co, Cod) in the upper phase (W/O) dropped, the capacitance (CB1, CBld) in the lower phase (BI) raised. At the same time, the W/O-BI inteffacial potential (ΔE), capacitance (Ci), and charge-transfer current (ict) decreased.After the n-heptane content reached 1%, with the increase of the n-heptane content, ΔE, Ci and ict demonstrated no significant change.

Interfacial Electric Properties Between W/O and Bicontinuous Microemulsions of SDS/n‐C5H11OH/n‐C7H16/H2O System

In the system of SDS/n‐C₅H₅OH/n‐C₇H₁₆/H₂O with the weight ratio of SDS/n‐C₅H₁₁OH/H₂O system at 5.0/47.5/47.5, the upper phase of the system was W/O microemulsion, and the lower phase was the bicontinuous microemulsion. When the n‐heptane content was less than 1%, with the increase of the n‐heptane content, the capacitance (C_o, C_od) in the upper phase (W/O) dropped, the capacitance (C_BI, C_BId) in the lower phase (BI) raised. At the same time, the W/O‐BI interfacial potential (ΔE), capacitance (C_i), and charge‐transfer current (i_ct) decreased. After the n‐heptane content reached 1%, with the increase of the n‐heptane content, ΔE, C_i and i_ct demonstrated no significant change.
