Activation behaviour and dielectric relaxation in polyvinyl alcohol and multiwall carbon nanotube composite films

The dc and ac electrical transport property of Polyvinyl Alcohol-Multiwall Carbon Nanotubes (PVA-MWNT) composites has been investigated within a temperature range 77≤T≤300K and in the frequency range 20Hz to 1MHz. The temperature variation of dc conductivity gives the presence of two different activation energies. The dielectric properties of the samples have been explained in terms of electric...

The 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...

Effects of ultrasound time on the properties of polyvinyl alcohol-based nanocomposite films

Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. One of the most important methods for dispersing nanoparticles in polymers is the use of ultrasound radiation. Polyvinyl alcohol-montmorillonite (PVA-MMT) nanocomposite films were prepared via solvent casting method. Materials and Methods: The effects of different ultrasound ti...

Micropatterning of silver nanoclusters embedded in polyvinyl alcohol films.

Direct laser writing has been utilized to fabricate highly photostable fluorescent nanocluster microstructures in an organic polymer poly(methacrylic acid), where the carboxyl functional group is reported to play a vital role in nanocluster stabilization. In this Letter, we demonstrate that not only the polymer containing the carboxyl functional group, but also the polymer comprising the hydrox...

Synthesis and characterization of Polyvinyl Alcohol-Polypyrrole-Silver nanocomposite polymer films

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...
