Fabrication of flowerlike polymer superstructures using polymer/zeolite composites prepared with supercritical CO(sub 2)

Article Abstract:

A route to the fabrication of unique flowerlike polymer superstructures with uniform petals at the nanoscale is reported. Polymer/zeolite composite is first prepared by loading corresponding monomer and initiator into the channels of the host zeolite with the aid of supercritical (SC) CO(sub 2) followed by thermal polymerization of monomers in the channels of the zeolite.

Compressed CO(sub 2) in AOT reverse micellar solution: Effect of stability, percolation, and size

Article Abstract:

The effects of the compressed CO(sub 2) in sodium bis-2-ethylhexylsulfosuccinate (AOT)/decane reversed micellar solution on the stability of the micelles, interface, and micelle/micelle interactions were studied. It was found that the compressed gas could increase the solubilization of water considerably, and the stabilized one-phase microemulsion was formed.

Ultrasonication-induced formation of silver nanofibres in reverse micelles and small-angle X-ray scattering studies

Article Abstract:

A simple method is proposed which synthesizes nanostructures directly from sodium bis(2-ethylhexyl) sulfosuccinate micelles with the aid of low-intensity ultrasonication. Direct microstructural information about the reverse micelles after ultrasonication is provided by small angle X-ray scattering.
