Molecularly engineered nanocomposites: layer-by-layer assembly of cellulose nanocrystals

Biomacromolecules. Nov-Dec 2005;6(6):2914-8. doi: 10.1021/bm050333u.

Abstract

Cellulose nanocrystals are promising as a new class of reinforcing material for the preparation of nanostructured composites. We report here the preparation of cellulose nanocrystal multilayer composites with poly(diallyldimethylammonium chloride) using layer-by-layer assembly (LBL) technique. The LBL assembly was characterized with UV-Vis spectroscopy and ellipsometry. The average thickness of a single bilayer was found to be 11 nm. AFM and SEM characterization revealed uniform coverage and densely packed cellulose crystal surface.
