“…The SEM image shown in Figure 5 reveals that an obvious gel-network microstructure was formed in 2.0 wt % THEED solution, indicating there was a pulling behavior with each other between THEED molecules, and thus the result of this study was similar to those reported in the literature [24,25]. Cross-linking effects were formed depending on the hydrogen bonds formed between the THEED molecules, and then present a three-dimensional network structure in THEED solutions, where the literature [26][27][28] interprets this pulling behavior as "self-assembly".…”

Based on the adsorption mechanism analysis of polyhydroxy organic compound on a shale surface, a novel polyhydroxy organic amine shale hydration inhibitor N, N, N′, N′-tetrakis (2-hydroxyethyl) ethylenediamine (THEED) was synthesized via a nucleophilic reaction by using diethanolamine and dibromoethane as raw materials. Its structure was characterized by Fourier transform infrared spectrometry (FTIR), Hydrogen Nuclear Magnetic Resonance (1H NMR) and Liquid Chromatography Mass Spectrometry (LCMS). The inhibition performance of THEED was studied by a shale rolling recovery experiment, a linear expansion experiment and the particle size distribution experiment. Results showed the shale rolling recovery rate in 2.0 wt % THEED solutions was up to 89.6% at the rolling condition of 100 °C × 16 h, and the linear expansion height of artificial shale core in 2.0 wt % THEED solutions was just 4.74 mm after 16 h. The average particle size of Na-bentonite (Na-MMT) in fresh water was 8.05 μm, and it was observed that the average particle size has been increased to 124 μm in 2.0 wt % THEED solutions. The shale hydration inhibition mechanism of the novel inhibitor THEED was analyzed by FTIR, Scanning Electron Microscopy (SEM) and X-ray diffractometry (XRD), we concluded that the nice shale hydration inhibition performance of THEED was achieved by means of intercalation and adsorption onto the surface of shale. The superior shale hydration inhibition property makes THEED promising in maintaining wellbore stability in drilling engineering.

“…Both of their surface activities are superior to that of the monomeric surfactant Glu(12) (Burczyk et al, 2001) (CMC 1.46 × 10 −4 mol L −1 , γ cmc 34.4 mN m −1 ). In the current study, the surface tension of 7d is higher than those of 7b and 7c, possibly due to the entanglement or self-coiling (Li et al, 2014a) of long hydrophobic chains, affecting their orientated arrangement in surface, and, therefore, the ability to reduce the surface tension. Bao investigated the effect of hydrophobic chains on surface activity of silicon-based gemini surfactants, and found a similar variation trend: γ cmc decreased initially and then increased with the increasing length of hydrophobic chains (Bao et al, 2017).…”

“…3b, peaks of small aggregates were found at 2.9 and 4.4 nm for 1 × 10 −4 M and 6 × 10 −5 M of 7b. According to some previous reports (Li et al, 2014a;Tian et al, 2012;Wang et al, 2011), the small aggregates of R h of around 1 nm are generally regarded as micelles, and the large aggregates of R h of 70-110 nm are vesicles. Yoshimura et al (2013) investigated the aggregates of 2CnLac gemini surfactants with a diameter of 4-12 nm, which were confirmed as micelles based on their size.…”

A group of novel sugar‐based gemini surfactants, N, N′‐bis(2‐hydroxy‐3‐alkyloxylpropyl) ‐N, N′‐bis(gluconylamide)‐ethylenediamine (alkyl: n‐C8H17, n‐C12H25, n‐C14H29, n‐C16H33), were synthesized and characterized. Their surface properties, including surface tension, γ, critical micelle concentration, CMC, maximum surface excess, Гmax, minimum area per molecule, Amin, and standard free energy of micellization and adsorption, normalΔGm0 and normalΔGads0, were investigated. The members of this family could reduce the surface tension of water to approximately 20–25 mN m−1 at the concentration level of 10−5 mol L−1, considerably lower than that commonly achieved with monomeric surfactants. Their adsorption and aggregation behavior were further studied by means of dynamic light scattering and X‐ray diffraction. The relationship of the aggregate size of the synthesized gemini surfactants with the length of the hydrocarbon chain and their concentration was discussed.

“…Decreasing the hydration around the heads leads to increasing their bond strength with the associated counterions. Increasing the hydrocarbon tail leads to decreasing the number of counterions as an ordinary result of increasing the molecular weight (Kamboj et al, ; Li et al, ; Zhi et al, ), which lead to decreasing the experimental degree of counter ion dissociation ( α ) (Table ). Elevating the solution temperature leads to weakening of the bond strength between the surfactant head and the associated counter ions (Ali et al, ; Shaban et al, ), which leads to an increase in the degree of counterion dissociation (Table and Fig.…”

The surface parameters of some cationic surfactants having different hydrophobic alkyl chains were assessed in aqueous solution using different techniques; surface tension, ultraviolet‐Visible (UV–Vis) spectroscopy, and conductivity measurements. The obtained critical micelle concentration (CMC) for N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethyloctan‐1‐aminium bromide (DBAO), N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethyldodectan‐1‐aminium bromide (DBAD), and N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethylhexadectan‐1‐aminium bromide (DBAH) in aqueous solution using three techniques are nearly the same. Increasing the hydrophobic chain length enhances micelle formation. Raising the solution temperature from 25 to 65 °C also shows the same trend. The thermodynamic calculations outlined the adsorption propensity of the surfactants at the surface compared to their affinity to form micelles. Both micellization and adsorption processes are enhanced with both the hydrocarbon elongation and with raising the solution temperature. The effect of the surfactant tail on the preparation process of the silver nanoparticles (AgNP) was assessed and confirmed using transmission electron microscope (TEM), dynamic light scattering (DLS), and UV–Vis spectra. Increasing the surfactant tail leads to a smaller particle size with a narrow distribution. The stability of the prepared AgNP is enhanced with hydrophobic surfactant tail elongation as proved with increasing the zeta‐potential of the prepared AgNP colloid. The foaming power, interfacial tension, and emulsification stability of the DBAO, DBAD, and DBAH surfactants were determined. The DBAO, DBAD, and DBAH surfactants showed good antimicrobial activities against both bacteria (Gram positive and negative) and fungi, which have been enhanced because of incorporation of AgNP.
