We have studied the surface-smoothing effect of an ultrathin germanium (Ge) layer on silver (Ag)-silica (SiO2) nanocomposite films for superlensing applications. Our experimental results indicate that inserting a thin Ge layer below the silver-silica composite films can reduce the final surface root-mean-squared (RMS) roughness to under 1 nm. Additionally, the metal nanostructure plays a role i...

The design methodology and realization of nanocomposite films aiming for mechanical (superhardness, toughness) and functional (optical, microelectronic) properties were discussed in this paper. Superhard TiCrCN and nc-TiN/a-SiNx films and super-tough nc-TiC/a-C(Al) films were prepared through co-sputtering method by optimal design of microstructure. The nanocrystalline silicon (nc-Si) passivate...

A series of bacterial cellulose-poly(2-hydroxyethyl methacrylate) nanocomposite films was prepared by in situ radical polymerization of 2-hydroxyethyl methacrylate (HEMA), using variable amounts of poly(ethylene glycol) diacrylate (PEGDA) as cross-linker. Thin films were obtained, and their physical, chemical, thermal, and mechanical properties were evaluated. The films showed improved transluc...

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...

This work reports the preparation, characterization and application as both electrochromic materials and electrochemical sensors of novel materials: carbon nanotubes/ruthenium purple nanocomposites. Using an innovative route based on a heterogeneous electrochemical reaction involving iron oxide species encapsulated within the cavities of the carbon nanotubes, the nanocomposite materials were ob...

A novel Zr,Ce-TiO2/SiO2 nanocomposite thin film was successfully prepared with various amounts of Zr4+ and Ce4+ as codopant ions for self-cleaning applications. A thin film was coated on a tile substrate by dip-coating and porous Zr,Ce-TiO2/SiO2 was obtained after heat treatment for 2 hours at 500 °C. The SEM images an...

We develop a facile, effective and filter free infiltration method to fabricate high performance, freestanding and superthin epoxy nanocomposite films with directly synthesized Sing-Walled Carbon Nanotubes (SWNTs) film as reinforcement skeleton. It is found that the thicknesses of the nanocomposite films can be easily controlled in the range of 0.5-3 μm by dripping target amount of acetone dilu...

Mixed-phase TiO2 nanocomposite thin films consisting of anatase and rutile prepared on commercially pure Ti sheets via the electrochemical anodization and annealing treatments were investigated in terms of their photocatalytic activity for antibacterial use around dental implants. The resulting films were characterized by scanning electron microscopy (SEM), and X-ray diffraction (XRD). The topo...

In this work, ZnO:TiO2 nanocomposites thin films were produced, and electrical properties evaluated. Nanocomposite nanoparticles used as film source in the preparation which was produced using hydrothermal synthesis different concentrations. Spin coating process adopted of films. pure TiO2,and 1:5 1:2 concentrations prepared. Electrical composites assessed where capacitance – voltage conductanc...

The influences of anionic sodium dodecylsulfate (SDS) and cationic Hexadecyltrimethylammonium bromide (HTAB) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited CoFe-BaFe12O19 composite thin films were studied. Sulphate bathes with natural pH containing 0 to 2 g/L surfactants were used for electroplating at room temperature. Field emissi...
