Dynamic responses in polymer-clay gels
(2005)The shear orientation of three polymer-clay gels has been investigated by means of small angle neutron scattering (SANS). The gels have the same polymer and clay concentrations but different polymer molecular weight. The ...

From beads-on-a-string to colloidal aggregation: novel crystallization phenomena in the PEO-SDS system
(1999)The anionic surfactant sodium dodecyl sulfate (SDS) interacts strongly with poly(ethylene oxide) (PEO) in aqueous solution, forming micellar aggregates attached to the polymer chains above the so-called critical association ...

From colloidal aggregates to layered nanosized structures in polymer-surfactant systems. 1. Basic phenomena
(2001)In this work, we examine the rich crystallization behavior that occurs in PbII/S-II/poly(ethylene oxide) (PEO)/sodium dodecyl sulfate (SDS) systems, in which the anionic surfactant interacts strongly with the polymer ...

High-molecular-weight symmetrical multiblock copolymers: Synthesis by RAFT polymerization and characterization
(2013)High-molecular-weight (MW) symmetrical multiblock copolymers, based on the hydrophobic monomers styrene (Sty) and methyl methacrylate (MMA), and the more polar monomer, 2-vinyl pyridine (2VPy), were prepared using stepwise ...

Large scale structures in nanocomposite hydrogels
(2005)The physical picture of the large scale structures in nanocomposite hydrogels and some of their unique behavior were discussed. The aqueous solutions of the synthetic hectorite type clay, Laponite RD (LRD) and poly(ethylene ...
