- Abstract:
- ... Chitosan with low (25 kDa) and high molecular weight (2100 kDa) were used to enhance performances of paper made from steam-exploded bamboo fibers and nanofibrillated cellulose. Chitosan solutions with concentrations of 0–1.0 wt% were manually applied on paper surface using a facile coating approach with a wire bar. Effects of chitosan coatings on morphology, thermal stability, wettability, mechani ...

For these reasons, many applications consider the use of graphene based materials (GBM), such as carbon thin films, instead of graphene. In this work, the aim was to produce GBM, by sputtering deposition, from a graphite target. The ability to red ...
