Wormlike micelles formed by ultra-long-chain nonionic surfactant
Wormlike micelles (WLMs) formed by different types of ultra-long-chain surfactants have been well studied except for nonionic ones. Here in this paper, a series of ultra-long-chain nonionic surfactants UCn-350 (n

Correlating surface activity with structural and environmental parameters for alkylamidosulfobetaine surfactants
Surface activities of 3-(N-alkylamidopropyl-N,N-dimethyl ammonium) alkanesulfonates [(U)n-DAS-m] and their dependence on the environmental and structural parameters were studied systemically. Environmental parame...

Basic Properties of Wormlike Micelles
Surfactants are probably the most fascinating family of small amphiphilic molecules, not only because of their everyday use in our life, but also because of their attractive macroscopic properties—all of which...

Light-responsive Wormlike Micelles
UV/Vis light as a trigger displays a set of advantages over other types of stimuli in terms of its “clean” character, low cost, and precise spatial localization, and for these reasons it has been widely exploi...

Chapter
pH-Responsive Wormlike Micelles
pH has been known for a long time and frequently used as a facile, inexpensive trigger to control molecular assemblies and thereby the bulk properties of the corresponding solutions. pH-responsive WLMs have be...

Other Types of Smart Wormlike Micelles
In comparison with the widely reported triggers described in previous chapters—namely temperature, pH, and light—this chapter discusses triggers which have been far less documented: redox potential and hydroca...

Chapter
CO2-Responsive Wormlike Micelles
Despite its extensive use, pH as a trigger has several drawbacks including the need of stoichiometric quantities of acid and base, the accumulation of by-products, and costly disposal. In this context, the wea...

Applications of Smart Wormlike Micelles
The end purpose of formulating smart wormlike micelles is undoubtedly to use them for practical applications. Their micellar structure and reversibly switchable viscoelastic properties offer opportunities for ...

In-Situ Formation of Viscoelastic Wormlike Micelles in Mixtures of Non-Surface-Active Compounds
Viscoelastic fluids based on surfactant self-assembled wormlike micelles have been in focus over the past decade. In this work, we report wormlike micellar solutions formed in situ by simply mixing two non-surfac...

Chapter
Thermo-responsive Wormlike Micelles
This chapter summarizes findings on the simplest trigger applied to wormlike micellar: temperature. Thermo-thinning systems are not discussed since a viscosity decrease with temperature is a rather general cha...

Effect of a Hydrophilic Head Group on Krafft Temperature, Surface Activities and Rheological Behaviors of Erucyl Amidobetaines
Ultra-long-chain amidobetaine surfactants have become one of the hot topics recently, but the influence of the hydrophilic head group on the aggregation behaviors and the correlation between surface activities...

Dispersion of single-walled carbon nanotubes in aqueous solution with a thermo-responsive pentablock terpolymer
Single-walled carbon nanotubes (SWNTs) were dispersed in pure water with a thermo-responsive amphiphilic PNIPAM150-F108-PNIPAM150 pentablock terpolymer in comparison with its precursor PEO136-PPO45-PEO136 (F108) ...

Thermoviscosifying polymer used for enhanced oil recovery: rheological behaviors and core flooding test
Polymer flooding represents one of the most efficient processes to enhance oil recovery, but the poor thermostability and salt tolerance of the currently used water-soluble polymers impeded their use in high t...

Synthesis and Surface Activities of Amidobetaine Surfactants with Ultra-long Unsaturated Hydrophobic Chains
Recent studies have shown that the surfactants bearing an ultra-long hydrophobic chain (>C18) exhibit unique self-assembly properties. However, their synthesis and surface activities have been less documented....

Synthesis and Properties of Alkylbetaine Zwitterionic Gemini Surfactants
A series of alkylbetaine zwitterionic gemini surfactants, 1,2-bis[N-methyl-N-carboxymethyl-alkyl-ammonium]ethane (C n Ab, n = 8, 10, 12, or 14), were synthesized by alkylation of...

Comparative study on interaction of bovine serum albumin with dissymmetric and symmetric gemini surfactant by spectral method
The interaction between bovine serum albumin (BSA) with N, N′-bis(dimethylalkyl) ethylammonium dibromide (C12C2Cm, m = 8, 12) was investigated by spectral methods. It can be seen that C12C2C8 and C12C2C12 mainly ...
