3D NMR Imaging of Foam Structures

  • Conference paper
Katachi ∪ Symmetry

Abstract

3D foam structures were measured using NMR imaging and their 3D geometrical properties were analyzed. Eight bubble polyhedra of a polyurethane foam specimen were extracted from 3D NMR image data using a newly developed 3D geometrical structure analysis program and quantitative geometrical data were measured for the first time for real foam systems. The results qualitatively agreed with the study by Matzke with soap bubbles but did not agree with the solution by Weaire and Phelan for 3D space division into equal volume cells with minimum partitional area. The reason for this disagreement is not clear, however, improved foam preparation and more systematic measurements using the method developed here may clarify this difference.
