Journal ArticleDOI
The Build-Up of Polyelectrolyte Multilayers of Microfibrillated Cellulose and Cationic Polyelectrolytes
TL;DR: Carboxymethylated MFC is thus a new type of nanomaterial that can be combined with oppositely charged polyelectrolytes to form well-defined layers that may be used to form, for example, new types of sensor materials.
Journal ArticleDOI
Developing fibrillated cellulose as a sustainable technological material.
Tian Li,Chaoji Chen,Alexandra H. Brozena,Junyong Zhu,Lixian Xu,Carlos Driemeier,Jiaqi Dai,Orlando J. Rojas,Akira Isogai,Lars Wågberg,Liangbing Hu +10 more
TL;DR: This work explores the use of fibrillated cellulose in the fabrication of materials ranging from composites and macrofibres, to thin films, porous membranes and gels, and discusses research directions for the practical exploitation of these structures.
Journal ArticleDOI

TL;DR: In this article, the optical properties of cellulose nanofibrils have been investigated and shown to be highly transparent with large light scattering in the forward direction, leading to a wide range of applications in optoelectronics such as displays, touch screens and interactive paper.
Journal ArticleDOI
Hydrodynamic alignment and assembly of nanofibrils resulting in strong cellulose filaments
Karl Håkansson,Andreas Fall,Fredrik Lundell,Shun Yu,Christina Krywka,Stephan V. Roth,Gonzalo Santoro,Mathias Kvick,Lisa Prahl Wittberg,Lars Wågberg,L. Daniel Söderberg +10 more
TL;DR: A process combining hydrodynamic alignment with a dispersion–gel transition that produces homogeneous and smooth filaments from a low-concentration dispersion of cellulose nanofibrils in water is presented.
Journal ArticleDOI
Nanoscale cellulose films with different crystallinities and mesostructures--their surface properties and interaction with water.
Christian Aulin,Susanna Ahola,Peter Josefsson,Takashi Nishino,Yasuo Hirose,Monika Österberg,Lars Wågberg +6 more
TL;DR: Small incidence angle X-ray diffraction revealed that the nanocrystal and MFC films exhibited a cellulose I crystal structure and that the films prepared from N-methylmorpholine-N-oxide, LiCl/DMAc solutions, using the Langmuir-Schaefer technique, possessed a cellulOSE II structure.
