Morphology and melt rheology of nylon 11/clay nanocomposites [PDF]
, 2006 Nylon 11 (PA11)/clay nanocomposites have been prepared by melt-blending, followed by melt-extrusion through a capillary. Transmission electron microscopy shows that the exfoliated clay morphology is dominant for low nanofiller content, while the ...

Multi-parameter in-process monitoring of clay dispersion during melt compounding with PLA
eXPRESS Polymer Letters, 2019 The time evolution of organoclay particle size and volume fraction, as well as the shear viscosity, are measured in-line for a series of Poly(lactic acid)/organoclay composites, using a rheo-optical die coupled to a prototype modular corotating twin ...

Adsorption and melting of hydrogen in potassium-intercalated graphite [PDF]
Physical Review B, 2009 Volumetric adsorption and quasielastic neutron scattering are used to study the diffusion and thermodynamics of sorbed H_2 in the graphite intercalation compound KC24. A sorption enthalpy of 8.5 kJ/mol at zero coverage is determined from H_2 adsorption isotherms.

Melt Intercalation in Montmorillonite/Polystyrene Nanocomposites
International Polymer Processing, 2005 Abstract Atactic polystyrene (PS) was used to study the effect of flow field (shear and/or elongational) on the intercalation of polymer/clay nanocomposites (PNC). Three grades of (PS), with different molecular weights, were compounded with an ammonium-modified montmorillonite (Cloisite 10A) in a twin-screw extruder (TSE).
