A new model for micellization beha..-ior of binary surfactant mixtures in solution is presented. A packing parameter, P* , has been introduced to describe the nonrandom mixing in mixed micelles. The significant feature of this model is that it considers asymmetric behavior ofmicellization in binary surfactant mixtures and predict5 the changes in the structures of mixed micelles with concentrati...

Using the notion of aggregation work, we construct a system of differential equations for the aggregation number of micelles which is a function of the parameters of micellization (parametric equations). There are explicit solutions for two important models of spherical micelles. Based on these solutions, we obtain an analytical expression for the equilibrium concentration of surfactant monomer...

We thoroughly investigate a simple model representative of the recently synthesized Janus particles, i.e., colloidal spherical particles whose surface is divided into two areas of different chemical composition. When the two surfaces are solvophilic and solvophobic, these particles constitute the simplest example of surfactants. The phase diagram includes a colloidal-poor (gas), colloidal-rich ...

Polymer functionalization of ordered mesoporous silicas (OMS) offer wide applications owing to their synergy properties. In this study, a new approach for polymer OMS is demonstrated by the co-condensation silica precursor and functional bearing triethoxysilane end-group in presence tailored poly (ethylene oxide)-b-polystyrene (PEO-b-PS) amphiphilic copolymer used as pore template. The novelty ...

Surfactants are adaptable amphiphilic compounds have an especially distinctive polar hydrophilic head and non-polar tail group. The surfactant is extensively used in each walk of life such as care products, domestic cleaners, pharmaceuticals, oil recovery, food handling, nanotechnologies due to decreasing the interfacial tension,. Micellization anionic surfactants potassium dodecyl sulphate (KD...

Supramolecular property systems composed of alkyltrimethylammonium surfactants and β-cyclodextrin were studied by means of a chemical probe. Solvolysis of 4-methoxybenzenesulfonyl chloride (MBSC) was used in the mixed systems with the aim of being able to determine the concentration of uncomplexed cyclodextrin in equilibrium with the micellar system. The surfactants used enabled us to vary the ...

Amphiphiles are molecules, which have covalently bonded hydrophilic (soluble in water) and hydrophobic (insoluble in water) groups. In aqueous solution such molecules self-assemble into aggregates of various shapes and sizes. Many amphiphiles (e.g., surfactants, block copolymers) form spherical aggregates called micelles above a certain amphiphile concentration, known as the critical micelle co...
