Gas sorption and permeation of physically treated glassy polymeric membranes is studied
from the viewpoint of the transport mechanism and the control of microvoids in the …

In 1855 Fick reported on the diffusion of liquid through a membrane and proposed that there
was an analogy between this process and that of heat conduction allowing him to transcribe …

Understanding the mechanisms of water sorption and diffusion in amorphous polymers is of
particular importance in relation to our ability to interpret related transport phenomena in …

Solvent sorption in polymers is of general interest for a wide variety of applications. It is well
known that solvent sorption in polymers depends on both solvent diffusion and the slow …

A chemiluminescent mechanophore, bis (adamantyl-1, 2-dioxetane), is used to investigate
the covalent bond scission resulting from the sorption of chloroform by glassy poly (methyl …

The industrial importance of penetrable and/or impenetrable polymer systems is evident
when one faces with a huge number of publications considering various aspects of diffusion …

A proton NMR imaging study has been conducted on the diffusion of methanol into poly-
(methyl methacrylate)(PMMA) after the cyclic absorptionand desorption of water and …

In many ways interfaces and surfaces dominate the behaviour of not only bulk polymers but
also thin film behaviour. The critical nature that the interface plays on numerous physical …

The well-known fluorophore, namely 1, 3, 6, 8-tetrakis [(trimethylsilyl) ethynyl] pyrene, has
been studied profoundly as a fluorescent sensor toward nitroaromatic compounds in …

A mathematical model was developed to explain the anomalous penetrant diffusion
behavior in glassy polymers. The model equations were derived by using the linear …
