“…The interfacial tensions are often 1.5−15 mN m −1 at CMC for the reported polymeric surfactants not containing fluorine. 12,22,25,26 Thus, in contrast to these polymeric surfactants, the interfacial property of PAF was better. On the other hand, the fluorinecontaining surfactants applied in EOR are commonly smallmolecule perfluoro-betaines, perfluoro-sulfobetaines, and carboxyl perfluoro-betaines, 27 and their interfacial tensions are often higher than 1.5 mN m −1 at CMC, 28 but the fluorinecontaining polymeric surfactants in EOR are not consulted in the literature.…”

Two novel monomers, 1H,1H,2H,2H-perfluoro-1-decyl p-vinylbenzyl ether (VF) and allyl-capped octylphenoxy poly(ethylene oxide) with the polymerization degree of 4 (AE), were synthesized. The polymeric surfactants (PAF) were synthesized with acrylamide, sodium 2-acrylamido-2-methylpropanesulfonate, AE, and VF. PAF could be expected to be applied in enhanced oil recovery to reduce water film on rock surface and interfacial tension for the oil reservoirs with the permeability of 100–10 (10–3 μm2). The introduction of VF together with AE causes PAF to display good interfacial activity and the reduction in wettability of aqueous solutions. Spherical nanometer micelles were formed, and CMC is 0.5 g L–1 in aqueous PAF solutions. The contact angle increased from 50.63° of pure water to 70.71° of 0.2 g L–1 PAF, and the interfacial tension was 0.009 mN m–1 for the 0.1 g L–1 PAF solution with 5 g L–1 NaCl and 0.3 g L–1 PS.

“…Landoll did pioneering work on cellulose-based polymeric surfactants in 1980s. , Since then, various cellulose-based polymeric surfactants have been synthesized including nonionic, ionic, fluorocarbon, and amphoteric. − Cellulose-based polymeric surfactants were generally synthesized by modification of hydrophilic cellulose backbones with hydrophobic long alkyl chains. Hydroxyl groups always have chemical handles that can react with hydrophobic chains containing epoxide, halide, acyl halide, isocyanate, or anhydride for the preparation of amphiphilic cellulose.…”

Epoxidized soybean oil (ESO) grafted hydroxyethyl cellulose (HEC) was prepared via ring-opening polymerization, in which the hydroxyl groups of HEC acted as initiators and the polymeric ESO were covalently bonded to the HEC. Hydrolysis of ESO-grafted HEC (ESO-HEC) was performed with sodium hydroxide, and the hydrolyzed ESO-HEC (H-ESO-HEC) products were characterized via Fourier transform infrared (FT-IR) and (1)H and (13)C nuclear magnetic resonance (NMR) spectroscopies, high-temperature gel permeation chromatography (HT-GPC), and differential scanning calorimetry (DSC). The results indicated that ring-opening polymerization of ESO occurred with the hydroxyl groups of HEC as initiators. The molecular weights of the H-ESO-HEC products were varied by adjusting the mass ratio of HEC and ESO. Through neutralizing the carboxylic acid of H-ESO-HEC with sodium hydroxide, novel polymeric surfactants (H-ESO-HEC-Na) were obtained, and the effects of polymeric surfactants on the surface tension of water were investigated as a function of concentration of H-ESO-HEC-Na. The H-ESO-HEC-Na was effective at lowering the surface tension of water to 26.33 mN/m, and the critical micelle concentration (CMC) value decreased from 1.053 to 0.157 g/L with increases in molecular weights of the polymeric surfactants. Rheological measurements indicated that the H-ESO-HEC-Na solutions changed from pseudoplastic property to Newtonian with increasing shear rate.

Regenerated cellulose forms a very important class of basic material with diverse applications because of its hydrophilicity and insolubility in water. Thus, one of the applications of regenerated cellulose is used to fabricate membranes. However, short operational lifetime is one of the disadvantages of the regenerated cellulose. In this research, surface modification of the cellophane membrane was carried out by silver nanoclusters. Silver colloids were formed in situ by chemical and photochemical reduction, and then, silver particles were deposited uniformly onto the surface of the cellophane membrane. The maximum amount of silver deposition was found to be 2.55% by weight in this modification. The modified and unmodified membranes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray analysis to indicate silver nanocrystalline cluster particles on the modified membrane. SEM images indicate well-dispersed silver particles with an average size of 0.65 μm on the membrane. XRD patterns showed that the size of the silver crystals was 3.9 nm. The surface properties of modified and unmodified membranes were studied by the contact angle. Water absorption, oxidative resistance, salt permeability, and thermal stability were investigated. This study revealed that the modified membrane is more resistant against the oxidative cleavage than the unmodified one moreover, the salt permeability increased after the treatment.
