The results showed that DeltaH(mic) values are negative, and there is an exothermal minimum between s=4 and s=6. Furthermore. the CMCs of the surfactants are in good agreement with literature values.展开更多

文摘The critical micelle concentrations (CMC) and the micelle-forming enthalpies (DeltaH(mic)) of gemini surfactants were first measured by the precise titration microcalorimetry. The results showed that DeltaH(mic) values are negative, and there is an exothermal minimum between s=4 and s=6. Furthermore. the CMCs of the surfactants are in good agreement with literature values.
