Shear Orientation of Viscoelastic Polymer-clay Solutions
Shear-induced structural changes in complex fluids of anisotropic species are very general phenomena, occurring in polymer solutions, liquid crystalline materials and block copolymer melts. The purpose of our work is to investigate the influence of shear on the structure of a highly viscoelastic, aqueous clay-polymer solution. Many structural models have been proposed for such solutions [1-3], ...
متن کامل3D Hierarchical orientation in polymer–clay nanocomposite films
Organically modified clay was used as reinforcement for HDPE using maleated polyethylene (PEMA) as a compatibilizer. The effect of compatibilizer concentration on the orientation of various structural features in the polymer-layered silicate nanocomposite (PLSN) system was studied using two-dimensional (2D) small angle X-ray scattering (SAXS) and 2D wide-angle X-ray scattering (WAXS). The dispe...
متن کاملPreferred Orientation in Microstructures
The microstructures of eutectics between compounds were studied for systems MnO-MnS, NaCl-NaF, NaBr-NaF, LiF-NaF, and FeO-FeS. With the exception of FeS, all the compounds had the NaC1-type structure. In the systems having only NaC1-type structures, the lamellas of the two eutectic phases had matching crystal orientations. There was less consistency among the eutectic systems, however, than bet...
متن کاملClay and Polymer-Based Composites Applied to Drug Release: A Scientific and Technological Prospection.
There has been a growing trend in recent years for the development of hybrid materials, called composites, based on clay and polymers, whose innovative properties render them attractive for drug release. The objective of this manuscript was to conduct a review of original articles on this topic published over the last decade and of the body of patents related to these carriers. A scientific pro...
متن کاملN in Clay Minerals : Ii . Orientation Effects
The effect of orientation of vermiculite particles on the diffusion of Na ion was measured by a tracer technique. The diffusion measurements were made on pellets prepared by pressing freezedried vermiculite in a cylindrical die and the diffusion coefficient evaluated by a thin-film boundary condition of Fick's law. Because flakes of vermiculite were highly oriented under the pressing force, it ...
