Electrical behaviour of native cellulose nanofibril/carbon nanotube hybrid aerogels under cyclic compression.
Hybrid aerogels consisting of cellulose nanofibers (CNF) and modified few-walled carbon nanotubes (FWCNT) are investigated under cyclic mechanical compression to explore "electrical fatigue". For this purpose the FWCNTs were hydrophilized, thus promoting their aqueous dispersibility to allow FWCNT/CNF hybrid hydrogels, followed by freeze-drying to obtain hybrid aerogels. The optimized compositi...
متن کاملAdsorption and desorption of cationic malachite green dye on cellulose nanofibril aerogels.
Ultra-light aerogels have been assembled from cellulose nanofibrils into hierarchically macroporous (several hundred μm) honeycomb cellular structure surrounded with mesoporous (8-60nm) thin walls. The high specific surface (193m2/g) and surface carboxyl content (1.29mmol/g) of these aerogels were demonstrated to be highly capable of removing cationic malachite green (MG) dye from aqueous media...

متن کاملShort Cellulose Nanofibril/polyvinyl Alcohol Nanocomposite Fibers
Short cellulose nanofibrils (SCNF) were investigated as a reinforcement for polyvinyl alcohol (PVA) fibers. SCNF fibers were mechanically isolated from hard wood pulp after enzymatic pretreatment. Various levels of SCNF were added to PVA and gel-spun into continuous fibers. The molecular orientation of PVA was affected by a combination of wet drawing during gel spinning and post-hot-drawing at ...
متن کاملCellulose Microfibril/Nanofibril and Its Nanocompsites
Cellulose micro/nanofibril (CMNF) as a reinforcing material for composites is becoming more and more attractive to researchers in composite science because of its potential lightweight and high strength. CMNF is generally prepared by either physical treatment, e.g., by a high pressure homogenizer and/or high pressure refiner, or chemical treatments, e.g., acid hydrolysis. In this study, attempt...
