In this study, poly (vinyl alcohol) (PVA), lithium perchlorate (LiClO4) and nano-sized titanium oxide (TiO2) were employed as host polymer, dopant salt and inorganic filler respectively. The influence of the inorganic filler on ionic conductivity, structural and morphological properties of the polymer matrix are investigated. Ionic conductivity of polymer electrolytes is measured by ac-impedanc...

The study describes the synthesis and characterization of zinc(II) minoxidil nanocomposite (1). The reaction between zinc(II) acetate, minoxidil, {C9H15N5O=minoxidil=(2,4-diamino-6-piperidine-1-yl) pyrimidine N-oxide)} as a ligand and KI as bridging agent, in methanol at 60°C leads to the formation of nano-sized Zn(II) minoxidil nanocomposite, 1. Characterization of (1) was carried out by eleme...

UV curing nanoimprint lithography is one of the most promising techniques for the fabrication of micro- to nano-sized patterns on various substrates with high throughput and a low production cost. The UV nanoimprint process requires a transparent template with micro- to nano-sized surface protrusions, having a low surface energy and good flexibility. Therefore, the development of low-cost, tran...

Nanogels are nano-sized three-dimensional polymer networks engineered by physical or chemical cross-linking of individual polymer chains loaded with drugs and nucleotides that swells in a good solvent

A novel nano – sized  manganese (II) coordination polymer, [{Mn(NCS)2(L)(H2O)2}(L)]n  , (1) (L- = 4,4'-Bipyridine), have been synthesized by a sonochemical process and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), IR spectroscopy and elemental analysis.  Direct calcination of the single crystals and nano-size...

This study focuses on the fabrication and electrical characterization of a polymer composite based on nano-sized varistor powder. The polymer composite was fabricated by the melt-blending method. The developed nano-composite was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FeSEM), and energy-dispersive X-ray spect...

In this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. Mechanical properties of micro and nano- composites, including tensile strength, elongation, and Young’s modulus, before and after ageing, were determined and analyzed. For this purpose, micro- and nano-sized CaCO3 particles were used as fillers to prepare micro-composites (c...
