Title: Visualisation of fluid migration into porous poly(vinylalkohol) using MRI techniques

Source: Molecular Physics Reports

Year : 2000

Abstract:

Information on migration of liquids into porous media and on mobility of the absorbed fluids is of great relevance for the theory and for many branches of the materials science. In this paper we use magnetic resonance microimaging to visualise migration of water and chloroform into porous poly(vinylalkohol) (PVA). The images taken using gradient echo fast imaging (GEFI) and constant time imaging (CTI) methods show differences, which are assumed to reflect the restriction of mobility of water molecules due to formation of hydrogen bonds with hydrophilic PVA.
