Effect of Temperature and Pressure on Surface Tension of Polystyrene in Supercritical Carbon Dioxide
(ACS Publications, 2007-02-15)The surface tension of polymers in a supercritical fluid is one of the most important physicochemical parameters in many engineering processes, such as microcellular foaming where the surface tension between a polymer melt ... -
Measurement of Surface Tensions in Aggregated Cells of the Embryonic Chick
(University of Waterloo, 2008-01-23)Cell surface properties are crucial to the mechanisms by which groups of cells organize themselves during embryogenesis, cancer metastases and tissue engineering. Measured surface tension values provide a quantitative ... -
Origin of change in molecular-weight dependence for polymer surface tension
(APS publishing, 2008-09-30)Self-consistent-field theory is used to reproduce the behavior of polymer surface tension with molecular-weight for both lower and higher molecular-weight polymers. The change in behavior of the surface tension between ... -
Reduction of polymer surface tension by crystallized polymer nanoparticles
(AIP Publishing, 2010-10-14)Self-consistent field theory is applied to investigate the effects of crystallized polymer nanoparticles on polymer surface tension. It is predicted that the nanoparticles locate preferentially at the polymer surface and ... -
Surface Tension of High Density Polyethylene (HDPE) in Supercritical Nitrogen: Effect of Polymer Crystallization
(Elsevier, 2009-06-10)Surface tension of a polymer melt in a supercritical fluid is a principal factor in determining cell nucleation and growth in microcellular foaming. This work focuses on the surface tension of a crystalline polymer, high ...
