M. Micic et al., Probing the lignin nanomechanical properties and lignin-lignin interactions using the atomic force microscopy, CHEM P LETT, 347(1-3), 2001, pp. 41-45
By combining atomic force microscopy (AFM) force and environmental scanning
electron microscopies (ESEMs), herein we present an evidence for the exist
ence of strong intermolecular forces, which are responsible for holding lig
nin globules together in higher ordered structures. Based on this observati
on, we provide a support for the hypothesis that lignin globules consist of
at least two individual spherical layers, with space in between filled wit
h solvent or gas. (C) 2001 Published by Elsevier Science B.V.
