“…In the previous study, we utilized Monte Carlo simulation to examine the effects of diblock copolymer on the interfacial properties of A n / A m B m / B n polymeric blends [ 26 , 27 ], and illustrated that the interfacial width, density distribution, and orientation of the diblock copolymer strongly depended on the diblock copolymers’ chain properties. In recent years, dissipative particle dynamics (DPD) simulations became a vital tool for studying the physicochemical properties of polymeric blends, including phase behavior, dynamics, and morphology evolution [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. Specifically, Groot et al [ 41 ] employed DPD simulation to calculate the interfacial tension of immiscible polymer blends.…”

We investigated the interfacial properties of symmetric ternary An/AmBm/Bn and An/Am/2BmAm/2/Bn polymeric blends by means of dissipative particle dynamics (DPD) simulations. We systematically analyzed the effects of composition, chain length, and concentration of the copolymers on the interfacial tensions, interfacial widths, and the structures of each polymer component in the blends. Our simulations show that: (i) the efficiency of the copolymers in reducing the interfacial tension is highly dependent on their compositions. The triblock copolymers are more effective in reducing the interfacial tension compared to that of the diblock copolymers at the same chain length and concentration; (ii) the interfacial tension of the blends increases with increases in the triblock copolymer chain length, which indicates that the triblock copolymers with a shorter chain length exhibit a better performance as the compatibilizers compared to that of their counterparts with longer chain lengths; and (iii) elevating the triblock copolymer concentration can promote copolymer enrichment at the center of the interface, which enlarges the width of the phase interfaces and reduces the interfacial tension. These findings illustrate the correlations between the efficiency of copolymer compatibilizers and their detailed molecular parameters.

“…29 Several different combinations of a high HLB surfactant and a low HLB surfactant have been used to produce stable emulsions. [29][30][31][32] According to the obtained results, T60, T80, and B58 were selected as hydrophilic surfactant for aqueous phase and span 20, 40, 60, and 80 were selected as hydrophobic surfactant for oil phase, as shown in Table IV.…”

Emulsion electrospinning using natural and synthetic polymers, including two dissimilar materials is a promising technique for nanofibers fabrication in a core/shell configuration for tissue engineering, controlled or sustained drug delivery and dressing applications. In this study, we designed and fabricated core/shell nanofibers based on polycaprolactone (PCL) as core material and poly(vinyl alcohol) (PVA)‐gelatin (GEL) blend as shell materials (PCL/PVA‐GEL) to achieve high mechanical properties, good cell growth, and proliferation via emulsion electrospinning. The effect of water to acetic acid ratio in the solvent system (8:2, 7:3, 6:4, 5:5) and also type and concentration (3, 5, 7 w/v %) of surfactant on emulsion stability and nanofibers morphology were investigated. The emulsion containing 2% Tween80 and 1% Span60 as surfactants were selected by considering the stability of emulsion and uniform fiber morphology. In the tensile strength and elongation at break, 53 and 8% increase in the crosslinked wet state of the PCL/PVA‐GEL nanofibers compared with PVA‐GEL nanofibers were observed respectively. The cell culture results indicated that the PCL/PVA‐GEL nanofibers surface has presented suitable interaction with fibroblast cells and cells attached and proliferated well on the fabricated substrate within 24 and 48 hours and also would be a good candidate for biomedical applications. © 2019 Wiley Periodicals, Inc.

The surfactants were mixed by stirring at 1500 rpm for 10 min (appropriate for surfactants of HLB 8-16, as reported in previous studies [19,20]. An HLB 14 surfactant afforded the best performance at 0.2 wt%.…”

Diesel fuel exhibits excellent combustion characteristics and stability. However, diesel use is becoming restricted because of its associated environmental problems. Fuel emulsification, which increases efficiency and reduces pollution, became the solution of environmental problem. In this study, five water:diesel emulsions with mass ratios (0.3, 0.6, 1.0, 1.2, and 1.5) via ultrasonication were synthesized with and without surfactant. The optimal water:diesel ratio (=1:1) of an emulsion containing the surfactant was found by analyzing fuel concentration, mixing time, and viscosity. The combustion characteristics of single-droplet optimal emulsions were studied through ignition delay, burning rate, and total droplet lifetime at high temperature (400–700 °C) and pressure (1–15 bar), and micro-explosion phenomenon was observed. Although the ignition delay of emulsion increased, the total lifetime of the emulsion droplet was lower than that of diesel under 5 bar, 600 °C condition.
