Circuit elements in carbon nanotube-polymer composites

Abstract

A simple technique has been realized for characterizing the degree of carbon nanotube dispersion in polymer matrices based on the AC impedance spectra, which reveals the nature of circuit elements in the composites, i.e. film resistance and capacitance. A model is proposed to account for nanotube migration in the polymer matrix. 2004 Elsevier Ltd. All… (More)
