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 کاملStudies on the use of recombinant spider silk protein/polyvinyl alcohol electrospinning membrane as wound dressing
A series of wound membranes of polyvinyl alcohol and recombinant spider silk protein (pNSR16) was prepared by electrospinning. The membrane was analyzed by scanning electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy. The result showed that the three factors that affected average fiber diameter from high to low were, voltage, flow speed, and solidification ...
متن کاملThe Interaction Effects of Montmorillonite and Glycerol on the Properties of Polyvinyl Alcohol-montmorillonite Films
Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. Depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. The effects of montmorillonite (MMT), glycerol (GL), and thei...
متن کاملPolyvinyl alcohol particle superficial morphology.
We appreciated the research by Derdeyn et al (1) from the Mallinckrodt Institute of Radiology concerning the size and suspension characteristics of polyvinyl alcohol (PVA) particles. We do agree that both size and suspension characteristics of PVA represent relevant parameters affecting the aggregation of particles during injection. In addition to these two variables, we considered further para...
متن کاملThe Polyvinyl Alcohol Sponge Model Implantation
Wound healing is a complicated, multistep process involving many cell types, growth factors and compounds(1-3). Because of this complexity, wound healing studies are most comprehensive when carried out in vivo. There are many in vivo models available to study acute wound healing, including incisional, excisional, dead space, and burns. Dead space models are artificial, porous implants which are...
