Evaluation of Dielectric Properties In Freeze Concentrated Polymer

Abstract

The relationship between the ice polycrystalline structure and the dielectric properties of a frozen gelatin gel were investigated. The cross-sectional images obtained by Micro-Slicer Image Processing System (MSIPS) were applied to the finite element method (FEM) to estimate the dielectric properties of the freeze concentrated gelatin gel. The overall dielectric properties of the frozen gelatin gel in this study were similar to that of pure water. Because the freeze concentrated gelatin gel contained water, and the relative effective permittivity, were different from those of gelatin powder. The results showed that the possibility of estimation of the dielectric properties in the freeze concentrated polymer gel utilizing with the MSIPS and FEM.
