Nanofibrillated cellulose films have garnered attention due to their interesting proprieties such as transparency and high mechanical strength. However, they are brittle, very hydrophilic, which is decreasing potential applications. We successfully achieved a simple effective chemical modification based on polymer grafting through plasticizer additions increase the performance of well improve c...

The present paper describes the preparation and characterization of Polyvinyl Alcohol-Polypyrrole-Silver Nanocomposite (PVA-PPy-Ag NC) films. The prepared films were conducting, freestanding, flexible, and robust. Silver nanoparticles (Ag NPs) were synthesized from an aqueous solution of silver nitrate using trisodium citrate as a reductant. The casting solution for the films was prepared by in...

It has been demonstrated that it is possible to produce methanol in one step reasonable amounts by electrolysis of CO 2 and H O gasses dissolved under 28 bar at 240 °C contact with an electrolyte consisting solid CsH PO 4 additions polyvinyl butyral (PVB) acting as a binder. The cathode was designed sandwich layer copper catalyst porous platinum electrode. anode consisted ruthenium metal covere...

objective(s): this paper describes synthesispolyvinyl alcohol/caf2:er nanofibers because of  its  photoluminescence properties.materials and methods:  first, caf2:er nanocomposite synthesized with co-precipitation method. in order to prepare polyvinyl alcohol (pva)/caf2:er nanofibers, caf2:er nanocomposites were added to the polyvinyl alcohol (pva) polymer. pva/caf2:er composite nanofibers were...

The mechanical properties of pristine graphene oxide paper and paper-like films of polyvinyl alcohol (PVA)-graphene oxide nanocomposite are investigated in a joint experimental-theoretical and computational study. In combination, these studies reveal a delicate relationship between the stiffness of these papers and the water content in their lamellar structures. ReaxFF-based molecular dynamics ...
