Abstract:The ultramicroscopic composition and supramolecular structure of wood matrix were investigated by methods of electron and atomic force microscopy (AFM). New data on specific features of the composition and cell wall structure of Juniper wood (Juniperus communis L.) were obtained. Native lignin was found to be water soluble. It was also shown that lignin does not constitute a continuous matrix between cellulose fibrils, but is deposited as spherical particles.
