TL;DR: Mild enzymatic hydrolysis has been introduced and combined with mechanical shearing and a high-pressure homogenization, leading to a controlled fibrillation down to nanoscale and a network of long and highly entangled cellulose I elements.
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.
Journal ArticleDOI
Cellulose nanofibrils - Adsorption with poly(amideamine) epichlorohydrin studied by QCM-D and application as a paper strength additive
TL;DR: In this article, cellulose nanofibrils were used together with a cationic polylelectrolyte, poly(amideamine) epichlorohydrin (PAE), to enhance the wet and dry strength of paper.
Journal ArticleDOI
Model Films from Native Cellulose Nanofibrils. Preparation, Swelling, and Surface Interactions
TL;DR: Native cellulose model films containing both amorphous and crystalline cellulose I regions were prepared by spin-coating aqueous cellulose nanofibril dispersions onto silica substrates and showed the best coverage for the low charged fibrils was achieved by using 3-aminopropyltrimethoxysilane (APTS).
Journal ArticleDOI
Enzymatic hydrolysis of native cellulose nanofibrils and other cellulose model films: effect of surface structure.
TL;DR: The hydrolytic potential of the cellulase mixture was found to be considerably affected by the nature of the substrates, especially their crystallinity and morphology, which affected the rate of enzymatic degradation of the nanofibril films much faster compared to the other types of cellulosic films.
