Haonan Wang, Charles C. Han, K Shimizu, Erik K. Hobbie, Z G. Wang, J C. Meredith, Alamgir Karim, Eric J. Amis, B S. Hsiao, E T. Hsieh
The phase diagram of coexisting liquid-liquid phase separation (LLPS) and crystallization in nearly isorefractive blends of statistical ethylene/hexane and ethylene/butene copolymers has been investigated. A variety of techniques that exploit

Rheology and Flow-Birefringence From Viscoelastic Polymer-Clay Solutions

January 1, 2002
Author(s)
G Schmidt, A Nakatani, Charles C. Han
The shear orientation of viscoelastic clay-polymer solutions was investigated by means of rheology and flow birefringence (δn). The polymer chains are in dynamic adsorption/desorption equilibrium with the clay particles to form a network. The elastic

Small Angle Neutron Scattering From Viscoelastic Polymer-Clay Solutions

January 1, 2002
Author(s)
G Schmidt, A Nakatani, Paul Butler, Charles C. Han
The influence of shear on viscoelastic polymer-clay solutions was investigated by means of small-angle neutron scattering (SANS) under shear. SANS measured the shear-induced orientation of polymer and platelets. With increasing shear rate an anisotropic
