Characterization of different types of cellulose by Dielectric spectroscopy (CAT#: STEM-ST-0367-WXH)

Introduction

Cellulose is a long linear polysaccharide polymer consisting of β-1,4-linked glucose units (C5H8O4)m, and exhibits in structural cell wall tissues of all higher plans and some algae, while some bacteria also excrete cellulose.

Principle

The principle of this technique is to apply an AC signal of small amplitude to an electrode immersed into an electrolyte. The initial disturbance (applied) and the response of the electrode is compared by measuring the phase shift of the current and voltage components and by the measurements of their amplitudes.

Applications

Used to study the response of a sample subjected to an applied electric field of fixed or changing frequency. DS describes the dielectric properties of a material as a function of frequency.
