Cobalt Addition

Nickel oxide (NiO)-based composite films with various Cobalt/Nickel (Co/Ni) ratios were fabricated, and the photochromic properties of the resulting films were evaluated. The NiO particle sizes in the composite films with Co/Ni ratios of 0~0.02 were 40~70 nm. Increase in the Co addition ratio to the composite films caused a decrease in the initial transmittance of the films, and the films with Co/Ni ratio of 0.005 and 0.01 showed a larger transmittance modulation. Co addition caused an increase in the bleaching and coloring rates, which were the largest in the film with Co/Ni ratio of 0.005.

AbstractWe report the non-epitaxial growth of highly textured (001) CoPt:B2O3 nanocomposite thin films that are deposited directly on thermally-oxidized Si wafers. Multilayers of Co/Pt/Co/B2O3 are deposited followed by appropriate thermal processing. The as-deposited films are disordered fcc CoPt phase, and magnetically soft. After annealing, an (001) orientation of CoPt-ordered grains is developed. The texture development is dependent both on the total film thickness and the annealing process. Nearly perfect (001) texture can be obtained in films with thinner initial layer thicknesses. Strong perpendicular anisotropy is shown to be related to this (001) texture.

Photochromic Properties

AgCl-resin photochromic composite films were prepared using AgNO3, HCl-EtOH, CuCl2ethanol solutions, and a urethane resin as starting materials. The AgCl particle size in the composite films, which was confirmed via TEM observations, was 23–43 nm. The AgCl composite films showed photochromic properties: coloring induced by UV-vis irradiation and bleaching induced by cessation of UV-vis irradiation. The coloring and bleaching speed of the composite film increases with increasing CuCl2mixing ratio.

The optical constants of Si/ZnO composite films grown on quartz glass substrates were determined in the spectral range 1.5–5.0 eV by spectroscopic ellipsometry using a rotating-analyzer ellipsometer. The structure of the samples was modeled by a two-phase (substrate–film) model, and the optical functions of the film were parameterized through different effective medium approximations. The results allowed us to estimate the microstructural film parameters, such as film thickness, the volume fractions of each of the constituents, and optical constants.

Wear Tests

Wear tests were performed on various expanded PTFE / epoxy composite films, using a 304 stainless steel pin, in a pin on disk configuration. The density and thickness of the expanded PTFE films were varied, and the effects on friction and wear were examined. It was found that there are trends for increased wear resistance with increasing density, and increasing film thickness. Wear rates less than 10−8 mm3/Nm were calculated on some of the composite films. The film thickness range from 75–510μm and the density ranged from 0.304 to 0.904 g/cm3. The tests were run at a 5N load and 1m/s sliding speed with varying sliding distances.

Forming Behaviour

Die Verpackung von Pouchzellen besteht aus einer dünnen Aluminiumverbundfolie, die zu Halbschalen tiefgezogen wird. Um diesen Prozess beherrschen zu können, muss zunächst das Umformverhalten der Folie charakterisiert werden. In diesem Fachartikel werden daher Erichsentiefungsversuche diskutiert. Aus ihnen geht hervor, dass das Verbundmaterial isotrop ist und die Parameter Foliendicke, Matrizenradien sowie Temperatur das Umformergebnis der Folie maßgeblich beeinflussen.   The packing of pouch cells consists of a thin aluminium composite film formed into half shells by deep-drawing. In order to be able to control this process, the forming behaviour of the film must first be characterized. Therefor, this article discusses the Erichsen cupping tests. These tests show that the composite material is isotropic and the parameters such as film thickness, die radius and temperature have a significant impact on the forming result of the film.
