Short 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 کاملCompression properties of polyvinyl alcohol--bacterial cellulose nanocomposite.
Despite the established use of total joint replacement for the treatment of advanced degeneration of articular cartilage, component loosening due to wear and osteolysis limits the lifespan of these joint prostheses. In the present study, nanocomposites consisting of poly(vinyl alcohol) (PVA) and bacterial cellulose (BC) nanofibers were investigated as possible improved cartilage replacement mat...
متن کاملPolyvinyl alcohol-cellulose nanofibrils-graphene oxide hybrid organic aerogels.
Hybrid organic aerogels consisting of polyvinyl alcohol (PVA), cellulose nanofibrils (CNFs), and graphene oxide nanosheets (GONSs) were prepared using an environmentally friendly freeze-drying process. The material properties of these fabricated aerogels were measured and analyzed using various characterization techniques including compression testing, scanning electron microscopy, thermogravim...
متن کاملbiodegradable carboxymethyl cellulose films modified by polyvinyl alcohol and cellulose nanowhiskers:(1) structural and physical properties
carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film, containing 0-10% cellulose nanowhiskers (cnw), was produced through casting method, while physical properties of the films being investigated. cmc-pvoh-cnw nanocomposites, were prepared with a diluted suspension of cellulose nanowhiskers. nanowhiskers suspension was prepared through acid hydrolysis of cotton linter by sulfuric a...
متن کاملPreparation and Characterization of Polyvinyl Alcohol-Chitosan Composite Films Reinforced with Cellulose Nanofiber
In this study microcrystalline cellulose (MCC) was oxidized by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation. The treated cellulose slurry was mechanically homogenized to form a transparent dispersion which consisted of individual cellulose nanofibers with uniform widths of 3-4 nm. Bio-nanocomposite films were then prepared from a polyvinyl alcohol (PVA)-chitosan (CS) ...
