“…For SDS in water and water‐TFE media when T < T *,

was small and positive ( i.e ., a slightly endothermic process). This may be possible because of solvent–solvent and surfactant–solvent interactions (Koya et al, 2013) and variation of the degree of hydration for the head groups of anionic surfactants with temperature (Batigöç et al, 2011). The standard enthalpy of micellization can also be evaluated by van't‐Hoff rationale for water, brine, and TFE/water solution:

normalΔ H_{m}^{0} = \frac{d ((), normalΔ G_{m}^{0} / T)}{d ((), 1 / T)}

An approach based on experimental and theoretical methods was used to compare the self-assembly [i.e., determination of the critical micelle concentration (CMC), degree of ionization (α) and counterion binding (β)] of sodium dodecyl sulfate (SDS) and didodecyl dimethyl ammonium bromide (DDAB) in deionized water and 10 mM NaCl and 10 (vol) % trifluoroethanol solutions. Experimental methods consisted of electrical conductometry, tensiometry, fluorimetry, and determination of Krafft temperature. A critical analysis of the thermodynamics of self-assembly by the Gibbs-Helmholtz equation and the van't-Hoff rationale provided values of several parameters, such as the change of Gibbs free energy and enthalpy change of micellization (ΔG 0 m and ΔH 0 m , respectively) and the Gibbs free energy of surfactant tail groups (ΔG 0 trans ). Interfacial properties, aggregation number (N agg ), micropolarity (I 1 /I 3 ), microviscosity (η), packing parameter (P), dielectric constant (D), anisotropy (r), and Stern-Volmer binding constant (K SV ) for SDS and DDAB in different temperatures and different systems were determined.

“…Consequently, 1.60 times lower cmc of DTAB than their aqueous medium have been observed. The diminishing of cmc of surfactants by increasing the concentration of OHA is because of the penetration of OHA in stern layer of micelle and thus destroying the water structure [39]. There is possibility OHA-surfactant interaction resultant mixed micelle formation (Fig.…”

“…Cationic gemini surfactants (CGS) have very useful practices for preparation of mesoporous substances (Koya et al, 2013), gene delivery (Chen et al, 2002), solubilization of oils (Din et al, 2009a), emulsification of monomers (Summers and Eastoe, 2003), and as germicides (Laatiris et al, 2008). Recently, there has been a greater need for cationic surfactants (CS).…”

In the present study, four novel imidazolium‐based cationic gemini surfactants (IBCGS) have been synthesized, having same hydrocarbon chain lengths and different spacers. The impacts of type and nature of spacer on Krafft temperatures (TK) have been examined. Micellization behaviors of IBCGS have been investigated at different temperatures above TK by both surface tension and specific conductivity measurements. Surface activity properties of aqueous systems have been calculated using the results of the measurement data. Critical micelle concentration (CMC), surface pressure at CMC (ПCMC), minimum area of head group (Amin), degree of counterion binding (β), degree of counterion dissociation (α), and maximum surface excess (Γmax) of IBCGS have been calculated with data of surface tension and specific conductivity. IBCGS have low CMC values than other imidazole categories of gemini and monomeric cationic surfactants. Micelle aggregation number (Nagg) values have been determined with the steady‐state fluorescence quenching method. The values of Nagg have been found in the range of 19–28. Additionally, the antibacterial activities of IBCGS on gram‐positive and gram‐negative bacteria have been investigated. IBCGS studied in this article have showed perfect antibacterial activity particularly against gram‐positive bacteria. The data obtained in this study may be benefical for the surfactant applications in different areas.
