Autor: M. Sanopoulou, J. H. Petropoulos, Dimitrios Stamatialis
Publikováno v: Macromolecules. 35:1021-1027
Results are reported of an experimental investigation of penetration rate and penetrant concentration profile, in the PMMA-methyl alcohol (MA) system. Penetration of liquid MA, at 22, 30, and 40 °C, along annealed or quenched films sandwiched betwee

Investigation of Case II Diffusion Behavior. 1. Theoretical Studies Based on the Relaxation Dependent Solubility Model
Autor: J. H. Petropoulos, Dimitrios Stamatialis, M. Sanopoulou
Publikováno v: Macromolecules. 35:1012-1020
A model previously shown to provide physically meaningful interpretation of a wide range of polymer−penetrant relaxation-induced non-Fickian (including case II) sorption kinetics, is used here as a basis for a deeper understanding of fundamental ca

Geometrical and Physical Modeling of Dilute Adsorbable Gas Flow in Porous Media: An Insider's Account of the Nicholson-Petropoulos Contribution
Autor: J. H. Petropoulos
Publikováno v: Molecular Simulation. 27:273-282
Our joint research grew out of our postdoctoral work with RMB on related topics, namely gas flow in single capillaries (DN) and in porous media (JP); which led us to the realization that the conventional interpretation (in terms of pore models) of ga

A proposed novel approach to the study of the dual-mode mechanism of dyeing nylon with acid dyes
Autor: J. H. Petropoulos, Toshiro Iijima
Publikováno v: Journal of Applied Polymer Science. 103:1055-1057
Study of the dual mode mechanism of dyeing nylon with acid dyes, consisting of Langmuir-type sorption on charged terminal amino groups, accompanied by Nernst-type uptake, known as “overdyeing,” is subject to complications primarily (but not exclu

Phenomenology and mechanisms of unidimensional stress-dependent micromolecular transport in a stiff-chain polymer. III. Effect of modification of the polymer
Autor: J. H. Petropoulos, Dimitrios Stamatialis, M. Sanopoulou
Publikováno v: Journal of Polymer Science Part B: Polymer Physics. 35:2593-2607
A detailed study of the kinetics and mechanism of micromolecular transport in cellulose acetate films containing 2.0 acetate groups per glucose unit (CA-2.0) is reported. The polymer was prepared by controlled hydrolysis of CA-2.45 films studied in p

Phenomena affecting the interferometric determination of concentration profiles of micromolecules diffusing along a stiff-chain polymer film
Autor: M. Sanopoulou, J. H. Petropoulos, Dimitrios Stamatialis
Publikováno v: Journal of Applied Polymer Science. 65:317-327
A detailed examination of the interferometric determination of penetrant concentration profiles during longitudinal penetration of micromolecular liquids in glassy polymer films, nonrigidly clamped between glass plates, is presented. Penetration of m

Analysis of the kinetics of vapor absorption/desorption in/from silicone rubber and cellulose acetate membranes in the presence of stagnant boundary layers
Autor: Matthias Wessling, H. Strathmann, J. H. Petropoulos, Dimitrios Stamatialis, Merope Sanopoulou
Publikováno v: Journal of membrane science, 1997(1), 165-175. Elsevier
The application of an interferometric technique (optical thickness meter, OTM) to the measurement of vapor sorption kinetics in both rubbery and glassy polymers is presented. In this technique, the membrane is formed by casting on a suitable glass su

Publikováno v: International Journal of Polymeric Materials. 32:63-73
A mathematical model predicting the behavior of systems consisting of hydrophylic polymer, water, and a low-molecular compound has been developed. The model takes into account the process of swelling of polymers during water sorption, the existence o
