Rheological properties of silicone-surfactant-based wormlike micellar solution

pH- and temperature-responsive supramolecular assemblies with highly adjustable viscoelasticity: a multi-stimuli binary system

“…The relaxation time can be expressed by τ R = ( τ b τ rep ) 1/2 . 100 When τ rep ≫ τ b ( i.e. , a single relaxation time), the fluid can be considered as a Maxwell fluid where τ R is mostly dominated by τ rep in the system.…”

“…The relaxation time can be expressed by t R = (t b t rep ) 1/2 . 100 When t rep ct b (i.e., a single relaxation time), the fluid can be considered as a Maxwell fluid where t R is mostly dominated by t rep in the system. 101 At 25 1C, a crossover frequency could be identified only for pH 6.0, which was used to determine the relaxation time: t R = 2p/o c .…”

Interface Adsorption and Aggregation Behavior of Sulfonate‐Based Anionic Silicone Surfactants in Aqueous Solution

“…Huang [24] synthesized a series of sulfonated silicone surfactants and studied their contact angles on glass and eucalyptus leaves to provide a theoretical basis for their application as spreading agents in agriculture. Aramaki [25] prepared sulfate-based silicone surfactants that could form low-temperature stable wormlike micelles solutions. Lin [26,27] designed and synthesized a series of sulfonated silicone surfactants and investigated their stability in aqueous solutions of acids or bases.…”

Synthesis and Micellization of Carbosilane Sulfonate Surfactants with Short Alkyl Chains

“…The flexible Si–O–Si can facilitate the siloxane surfactants (Si–O–Si) to arrange at the air/water interface with tight arrangement of CH 3 ; consequently, siloxane surfactants show remarkable properties, for example, distinctive surface activity and interfacial properties, superspreading behavior, less toxicity, etc. − Meanwhile, siloxane surfactants have received much attention in recent years and have been used in a variety of fields, such as polyurethane foam, personal care products, textile manufacture, agricultural adjuvants, and so on. To date, siloxane surfactants with different molecular architectures have been synthesized to investigate their fundamental interfacial properties, − for example, trisiloxane/tetrasiloxane surfactants, − , polysiloxane surfactants, and so forth. Tan and co-workers systematically studied the effect of the molecular architecture, headgroups, unsaturation, alkyl groups, linear versus “T”/umbrella-shaped trisiloxane, and tetrasiloxane on the surface and interfacial properties of siloxane surfactants. , It was demonstrated that structural variations play a major role in their physicochemical properties. − …”
