“…They are also present in biological systems by the name bio‐surfactant having lipophilic moieties (e. g. proteins or peptides generally) and hydrophilic groups (e. g. ester, hydroxyl, phosphates, carboxylate group or sugar). Presently, bio‐surfactants have got special importance over others for their bio‐degradability, eco‐friendly behaviour, low toxicity, high selectivity etc . However, their very high production costs have made their uses limited.…”

Amphiphiles or surfactants are widely known for its reducing power of interfacial tension and extraordinary rheological properties. Among the various classes of surfactants gemini surfactants, biosurfactants and polymeric surfactants are remarkable and distinguishable among the others for their structural diversity and profitable usefulness. Primarily, the performance of any surfactant can be determined by HLB (Hydrophile Lipophile Balance) value, an empirical parameter. This review attempts to clarify some of the terminology used in literature by providing illustration of classification, features and diverse applications of different surfactants.

“…The properties of hydrophobically associated polymers in water solutions are closely related to their molecular structures, especially the structures, concentrations, and distribution of hydrophobic groups. Generally, a hydrophobic monomer, such as N-alkyl acrylamide (C4-12) [13,14], N,N-dialkylacrylamide (C 4-12) [15,16], styrene derivatives [17], or F-containing acrylate [18][19][20], was used to react with anionic monomer (e.g., acrylamide, sodium acrylate, or 2methyl-2-acrylamide propyl sulfonic sodium) via ternary copolymerization to form a polymer aqueous solution with high surface activity and viscosifying ability. Hill et al found that when the concentrations of hydrophobic groups were the same, the hydrophobically associated polymers with hydrophobic micro blocks outperformed irregular hydrophobic association polymers in hydrophobic association [13].…”

A series of surfactive amphiphilic polymer PAADs were prepared from the copolymerization of sodium acrylate, dodecyl polyoxyethylene acrylate (DPA, a surfmer), and acrylamide under the action of a mixed initiating agent consisting of ammonium persulfate-sodium bisulfite/2,2′-azobis[2-(2-imidazolin-2-yl) propane] dihydrochloride. The aggregative behaviors of PAADs were explored by 13C nuclear magnetic resonance, a viscometer, and a surface tension instrument. It was found that the apparent viscosity and surface activity of PAADs were significantly improved by the increase of average sequence length of hydrophobic micro blocks, strong intermolecular hydrophobic association, or the formation of mixed micelles between hydrophobic micro blocks and micromolecular surface-active agent. The introduction of long-chain alkyls on molecular chains prolonged the average sequence length of hydrophobic micro blocks in molecular chains and enhanced the hydrophobic association between molecular chains and the tight arrangement of molecular chains on water surfaces, thereby increasing the surface activity. Moreover, the anionic monomer sodium acrylate on molecular chains, via electrostatic repulsion, promoted the conversion from intrachain association to intermolecular association and thereby facilitated the formation of dense interfacial films, enhancing the surface activity of water solutions. Then, the anion surfmer sodium dodecylbenzenesulfonate interacted with the hydrophobic micro blocks on the molecular chains to form mixed micelles, which accelerated the interchain association and enhanced the polymer surface activity. The novel polymeric micelle with higher viscosifying ability and surface activity was expected to be a promising oil drive agent for tertiary oil recovery.
