Research in porous structure of cellulose aerogel made from cellulose nanofibrils

Porous Materials from Cellulose Nanofibrils

Highly porous regenerated cellulose hydrogel and aerogel prepared from hydrothermal synthesized cellulose carbamate

Here, a stable derivative of cellulose, called cellulose carbamate (CC), was produced from Kenaf (Hibiscus cannabinus) core pulp (KCP) and urea with the aid of a hydrothermal method. Further investigation was carried out for the amount of nitrogen yielded in CC as different urea concentrations were applied to react with cellulose. The effect of nitrogen concentration of CC on its solubility in ...

Enzymatic hydrolysis of native cellulose nanofibrils and other cellulose model films: effect of surface structure.

Model films of native cellulose nanofibrils, which contain both crystalline cellulose I and amorphous domains, were used to investigate the dynamics and activities of cellulase enzymes. The enzyme binding and degradation of nanofibril films were compared with those for other films of cellulose, namely, Langmuir-Schaefer and spin-coated regenerated cellulose, as well as cellulose nanocrystal cas...

Comparative Study of Cellulose Nanofibrils Disintegrated from Different Approaches

The use of renewable materials has received a great deal of attention over the last several decades due to the environmental impact and finite resources of petroleum and other non-renewable resources. Cellulose nanofibrils are a type of nanomaterial made from natural resources like wood and non-wood plants, and they are considering promising alternative to existing materials in numerous fields ...

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 ...
