“…As expected, all the investigated phenylenediamine Gemini surfactants display micellization in water, with much smaller CMC values compared with traditional single hydrocarbon cationic surfactants such as dodecyl trimethyl ammonium chloride DTAC (CMC = 1.20 × 10 −2 mol L −1 ) (Abdel‐Salam and Ei‐Said, ). This indicates that Gemini surfactants have a stronger self‐assembling tendency in aqueous solution at lower concentrations than single‐chain monomeric surfactants, probably due to the increase of hydrophobic interactions.…”

In the present work, a two‐step method was adopted to synthesize a series of novel Gemini surfactants using N,N‐dimethylalkyl amines (alkyl length = C12, C16 and C18), epichlorohydrin, and n‐phenyllenediamine as starting materials. The products were characterized using mass spectroscopy (MS) and nuclear magnetic resonance spectroscopy (1H NMR). Systematic experiments were conducted to evaluate their surface activity, foaming properties, and antibacterial performance. Results showed the critical micelle concentrations (CMC) of the C12‐based, C16‐based, and C18‐based phenylenediamine surfactants were 3.295 × 10−3, 2.532 × 10−4, and 3.140 × 10−4 mol L−1 at 298 K, respectively, with corresponding surface tension (γcmc) values of 28.24, 31.95, and 35.06 mN m−1 under the same conditions. The Gemini surfactants showed not only good surface activity and foaming properties, but also demonstrated good antimicrobial performance against Gram‐positive and Gram‐negative bacteria and fungi.

“…a 0 is the area per head group at the micelle-solution interface. However the accurate determination of a 0 is rather difficult; therefore, a 0 has been replaced by A min, i.e., the area per head group at the air-solution interface [41]. Micelles formed by surfactants are assigned different shapes depending upon p values as [spherical: (0-0.33); cylindrical: (0.33-0.5); lamellar: (0.5-1)] [42].…”

The micellization behaviour of sodium dodecyl sulphate, sodium dodecylbenzenesulfonate, hexadecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, and cetylpyridinium chloride in water and in aqueous solutions of polyethylene oxide (PEO, molecular weight = 100,000) having concentrations (0.005-0.04 %, w/v) has been studied at different temperatures (288.15-318.15 K) using conductivity, surface tension, and viscosity methods. From conductivity measurements various micellar parameters, like critical micellar concentration (CMC), critical aggregation concentration (CAC), polymer saturation point (PSP), degree of ionization (b), and standard free energy of transfer (DG 0 t ), have been calculated. CAC values have been found to decrease with polymer concentration and increase with temperature. However, the PSP values increase with both polymer concentration and temperature for all surfactants. Similar parameters have also been calculated from surface tension data (CMC r , CAC r , PSP r ) along with other parameters such as maximum surface excess concentration at the air/water interface (C max ), minimum area per molecule (A min ), and packing parameter (p). The CMC r , CAC r , and PSP r values are smaller than the corresponding CMC, CAC, and PSP values, but both show similar behaviour with temperature and concentration of polymer. Various parameters indicate that the presence of the aromatic ring in the head group of surfactant decreases its interaction with PEO, whereas the increased hydrophobicity in the tail leads to stronger interactions with PEO. Viscosity studies further supplement the conclusions drawn from the above results.

“…From cost and performance considerations, gemini surfactants will likely be used in mixtures with conventional surfactants in the future. In present study, the synergistic effect of the two compound method that is being used in oil field production in recent years was studied in terms of IFT reduction for 3C 10 Then the hydrophobic groups of surfactant molecules 3C 10 -DS in the bulk solution cluster together into micelles which may solubilize surfactant molecules desorbing from the oil-water interface, and consequently the interfacial tension increases.…”

A new type of sulfonate gemini surfactant with three lipophilic alkyl chains (3C 10 -DS) was synthesized, and the structure of the product was confirmed by using the infrared spectrum and mass spectrum. Its critical micelle concentration (CMC) is 0.41 mmol/L, one order of magnitude lower than those of convectional (single-chain) surfactants, and the minimum surface tension is 27.6 mN/m. The interfacial tension (IFT) between the compound system of 3C 10 -DS and petroleum sulfonate (PS) and the simulated oil reaches ultra-low levels (10 -3 mN/m), and there exists significant synergistic effect between 3C 10 -DS and PS. The compound flooding system consisting of polymer and the mixture of 3C 10 -DS and PS can effectively improve oil recovery for high-medium permeability cores, and have a good application prospect in enhancing oil recovery.
