- Effects of Intramolecular Double Bonds on Micellar Surface Potential and Surface Charge Density of Icosapolyenoic Acids
この論文をさがす
説明
Micellar surface potentials (Δψ) of icosapolyenoic acids (IPA) having 25 double bonds were determined at 25°C from fluorescence intensity of ammonium 8-anilino-1-naphthalenesulfonate as a fluorescent probe. The surface potential, |-Δψ|, of IPA micelles decreased with increase in the number of double bond in the IPA molecule. Decrease in |-Δψ| by the introduction of a double bond in the IPA molecule was approximately 13.12mV at ionic strength 0.02mol dm-3. The relationship was represented well by the following equation : Δψ/mV=-108.0+13.12n, where n is the number of C=C double bonds in an IPA molecule. Surface charge density |-σ| of IPA micelles based on the Gouy-Chapman theory was found to diminish as n increased. The relationship can be expressed well by the following equation : σ/c cm-2=-3.386×10-6+2.463×10-6·(√n-√2), where n≥2.
