Mesostructured Polymer Materials Based on Bicontinuous Microemulsions

Bicontinuous Microemulsions under Steady Shear Flow

Dynamic response of microemulsions to shear deformation on the basis of twoorder-parameter time dependent Ginzburg-Landau model is investigated by means of cell dynamical system approach. Time evolution of anisotropic factor and excess shear stress under steady shear flow is studied by changing shear rate and total amount of surfactant. As the surfactant concentration is increased, overshoot pe...

Studying orthogonal self-assembled systems: microstructure of gelled bicontinuous microemulsions.

An orthogonal self-assembled system consists of different structures which coexist independently. Furthermore, the characteristic properties of the respective "base systems", i.e. of the systems which contain only one of the structures, are retained in the orthogonal self-assembled system. We have identified gelled bicontinuous microemulsions as orthogonal self-assembled systems and reported in...

Effect of multiple scattering on SANS spectra from bicontinuous microemulsions.

Small-angle neutron scattering is a powerful tool for investigating the microstructure of self-assembled systems. The domain length, d, and the correlation length, xi, are two measures of bicontinuous microemulsions that are often determined from coherent SANS spectra. Some microemulsions scatter strongly, however, so measured spectra can contain multiple coherent scattering, and neglect of tha...

Structure of microemulsions with gemini surfactant studied by solvatochromic probe and diffusion NMR.

The structure of microemulsions prepared by the anionic gemini surfactant didodecyl diphenyl ether disulfonate (C12-DADS) was investigated by a solvatochromic probe and nuclear magnetic resonance (NMR) diffusion measurements. The NMR measurements indicate the presence of bicontinuous and oil-in-water microemulsions depending on microemulsion composition. The absorbance spectra of the solvatochr...
