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...

The nanocomposite polyvinyl pyrrolidone (PVP) films containing Ag nanoparticles and Rhodamine 6G are prepared on the two-dimensional distinctive continuous ultrathin gold nanofilms. We investigate the optical properties and the fluorescence properties of silver nanoparticles-PVP polymer composite films influenced by Ag nanoparticles and Au nanoparticles. Absorption spectral analysis suggests th...

Interface issues are common and crucial in nanocomposites or nanohybrid systems since the interface area is enormous on the nanoscale. In the 0-3 polymer nanocomposites, in which nano-inclusions (0-dimension) are embedded in 3-dimensionally connected polymer matrix, enhanced dielectric permittivity could be induced by the interfacial polarization at the interfaces between the nano-inclusions an...

The nanocomposite web of calcium alginate and polyvinyl alcohol with varying proportion has been prepared by electrospinning and its application for wound healing is examined. Scanning electron microscope and Fourier transform infrared spectroscopy have been used to characterize the morphology and molecular fingerprint. The water vapour transmission rate of the blended nanofibre composite web h...

ZnO/Ag nanocomposites coated with polyvinyl chloride (PVC) were prepared by chemical reduction method, for anti-infection biomaterial application. There is a growing interest in attempts in using biomolecular as the templates to grow inorganic nanocomposites in controlled morphology and structure. By optimizing the experiment conditions, we successfully fabricated high yield of ZnO/Ag nanocompo...

In this investigation, we report facile synthesis of cadmium(II)-thioacetamide nanocomposites in the presence and absence of polyvinyl alcohol under ultrasonic irradiations, using cadmium acetate dihydrate (Cd(CH3COO)2.2H2O), potassium iodide (KI), thioacetamide (TAA, CH3CSNH2), and polyvinyl alcohol (PVA) as the starting materials. Results show that in the presence of polyvinyl alcohol size...

The development of rapid and reliable processes for the synthesis of nano materials is of great importance in the field of nanotechnology. In this paper, the synthesis of Chitosan/TiO2 nanocomposites was carried out by using LPD technology in aqueous medium. The method was performed by mixing the chitosan with TiO2 in the presence of polyvinyl alcohol as the capping agent. In this work, Chitosa...

This chapter describes the details of the synthesis of polyaniline (PAni) nanofiber reinforced polyvinyl alcohol (PVA) nanocomposites employing in-situ rapid mixing polymerization technique and the effect of SHI irradiation on the physico-chemical properties of the nanocomposites. Modifications in the morphology, conformation and the charge transport properties of the nanocomposites have been i...
