The Interdependence of the Lignin Content and Electrical Properties of Wood

A. Venkateswaran

Abstract


A linear relationship was found to exist between the percentage of acid-insoluble lignin content and both the permittivity and DC conductivity of vacuum-dried woods, woods conditioned at 65% relative humidity, and in both of the two major grain directions. This study shows that dielectric measurements could be developed into a nondestructive analytical tool for estimating acid-insoluble lignin content in woods.
