Porous Materials from Cellulose Nanofibrils

Cellulose fibers and nanofibrils for adhesive reinforcement

Introduction In wood industry, adhesive bonding is one of the key process steps. To ensure continuing technological progress in wood industry it is necessary to explore new possibilities of improvement in adhesive bonding. The potential routes for performance improvements suggested by a state of the art report issued by COST Action E13 Wood Adhesion and Glued Products (Dunky et al. 2002) focus ...

Drying cellulose nanofibrils: in search of a suitable method

Increasing research activity on cellulose nanofibril-based materials provides great opportunities for novel, scalable manufacturing approaches. Cellulose nanofibrils (CNFs) are typically processed as aqueous suspensions because of their hydrophilic nature. One of the major manufacturing challenges is to obtain dry CNFs while maintaining their nano-scale dimensions. Four methods were examined to...

Microemulsion systems for fiber deconstruction into cellulose nanofibrils.

A new method to produce cellulose nanofibrils (CNF) is proposed to reduce the energy demand during deconstruction of precursor fibers suspended in aqueous media. Microemulsions were formulated with aqueous solutions of urea or ethylenediamine and applied to disrupt interfibril hydrogen bonding. Compared to typical fibrillation of lignin-containing and lignin-free fibers, pretreatment with micro...

Spinning of Cellulose Nanofibrils into Filaments: A Review

Spinning of cellulose nanofibrils (CNF) offers promising opportunities to develop renewable fibers and filaments with strong, aligned structure. This review introduces recent findings on the relationship between the properties of CNF hydrogels, the spinning conditions and the performance of filaments obtained by dryand wet-spinning. For example, the filament Young’s modulus correlates with CNF ...
