“…There are several studies available on the wettability of single-chain surfactants on hydrophilic and hydrophobic surfaces but a limited number on Gemini ,− or double-chain surfactants. ,− Seredyuk et al have studied the wettability of a zwitterionic Gemini surfactant of dissimilar chain lengths on a porous paper surface. Cao et al studied the wettability of cationic Gemini surfactant [C 12 –C 6 –C 12 ]Br 2 on silica surface and showed initially there was an increase in contact angle (51–63°) with the increase in surfactant concentration, which then again decreased to 31° because of formation of surface aggregation by the surfactant molecules.…”

“…The wettability of anionic double-chain surfactant aerosol OT (AOT) was studied on both the low surface energy hydrophobic (PTFE and PMMA) and hydrophilic (glass) surfaces. ,, Harkot and Janczuk , found the surfactant formed a monolayer adsorption on the solid–water interface and adsorption density at air–water and PTFE–water interfaces were equal. However, the adsorption densities at PMMA–water and glass–water interfaces were different from that of the air–water interface.…”

The wetting of hydrophobic and hydrophilic solid surfaces by surfactant solutions is an important research topic recently because of its profound practical applications. The wettability of two double-chain surfactants (cationic, didodecyldimethylammonium bromide or DDAB, and anionic, aerosol OT or AOT) solutions on poly(tetrafluoroethylene) (PTFE) and glass surfaces has been investigated here. Different physicochemical parameters such as critical micelle concentration (CMC) and surface tension, contact angle, surface excess at air−water and solid-water interfaces, work of adhesion, and free energy of wetting have been estimated for two double-chain surfactants solutions and compared with the reported results of single-chain surfactants. The double-chain surfactant solutions showed maximum lowering of surface tension values (24.36 and 26.35 mN/m for DDAB and AOT, respectively) and a change in contact angle values from pure water on PTFE (∼38°for DDAB and AOT) and glass (∼26.5 and 24°for DDAB and AOT, respectively) surfaces compared to the conventionally studied single-chain surfactants. The surfactant molecules mostly formed a monolayer adsorption on both surfaces during the wetting process. The surface excess values of both of the surfactants on PTFE−water and glass−water interfaces are 0.759 and 0.850 times lower than that of the air−water interface, respectively.

“…Generally, the adsorption of the hydrophilic head group and PMMA surface of ionic surfactants is weaker than that of the hydrophobic end and PMMA. Therefore, the hydrophobic tail of the surfactant is polarly adsorbed on the surface of PMMA, and the ion head is oriented towards the aqueous phase, resulting in a decrease in energy at the solid-liquid interface with a negative slope, such as anionic surfactants sodium decylsulfate(SDS) 27 and bis(2-ethylhexyl) sodium sulfosuccinate (AOT), 20 cationic surfactants cetyltrimeth-ylammonium bromide (CBAT), cetylpyridinium bromide (CPyB), 28 dodecylethyldimethylammonium bromide C 12 (EDMAB), and benzyldimethyldodecylammonium bromide (BDDAB). 29 Surfactants with a positive slope usually have more than one hydrophilic group.…”

“…The experimental results have shown that double-chain surfactants can effectively form a dense wetting surface on the surface of polymer, improving surface wettability without affecting surface glossiness. 19,20 In addition, double-chain surfactants also have good antibacterial activity and can effectively prevent Grampositive bacteria. 21 Nihar Ranjan Biswal 19 found that compared to traditional single-chain cationic surfactants (CTAB), doublechain cationic surfactants (DDAB) and double-chain anionic surfactants (AOT) have lower minimum surface tensions and far lower contact angle.…”

“…Numerous conventional surfactants’ adsorption behaviors on the PMMA surface have been investigated and reported in the literature. Harkot et al explored the adsorption behaviors of anionic surfactant (AOT) [ 18 ] and cationic surfactants (C 12 (EDMAB), BDDAB) [ 19 ] on the PMMA surface. They found that the wettability of PMMA surfaces by the surfactants depends on the surfactants’ concentration to a large extent.…”

The adsorption behaviors of extended anionic surfactants linear sodium dodecyl(polyoxyisopropene)4 sulfate (L-C12PO4S), branched sodium dodecyl(polyoxyisopropene)4 sulfate (G-C12PO4S), and branched sodium hexadecyl(polyoxyisopropene)4 sulfate (G-C16PO4S) on polymethylmethacrylate (PMMA) surface have been studied. The effect of branched alkyl chain on the wettability of the PMMA surface has been explored. To obtain the adsorption parameters such as the adhesional tension and PMMA-solution interfacial tension, the surface tension and contact angles were measured. The experimental results demonstrate that the special properties of polyoxypropene (PO) groups improve the polar interactions and allow the extended surfactant molecules to gradually adsorb on the PMMA surface by polar heads. Therefore, the hydrophobic chains will point to water and the solid surface is modified to be hydrophobic. Besides, the adsorption amounts of the three extended anionic surfactants at the PMMA–liquid interface are all about 1/3 of those at the air–liquid interface before the critical micelle concentration (CMC). However, these extended surfactants will transform their original adsorption behavior after CMC. The surfactant molecules will interact with the PMMA surface with the hydrophilic heads towards water and are prone to form aggregations at the PMMA–liquid interface. Therefore, the PMMA surface will be more hydrophilic after CMC. In the three surfactants, the branched G-C16PO4S with two long alkyl chains exhibits the strongest hydrophobic modification capacity. The linear L-C12PO4S is more likely to densely adsorb at the PMMA–liquid interface than the branched surfactants, thus L-C12PO4S possesses the strongest hydrophilic modification ability and shows smaller contact angles on PMMA surface at high concentrations.
