Fluoropolymer binders for carbon nanotube-based transparent conductive coatings

This invention relates to flexible, transparent and conductive coatings and films formed using carbon nanotubes (CNT) and, in particular, single wall carbon nanotubes, with polymer binders. Preferably, coatings and films are formed from carbon nanotubes applied to transparent substrates forming one or multiple conductive layers at nanometer level of thickness. Polymer binders are applied to the CNT network coating having an open structure to provide protection through infiltration. This provides for enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or a combination thereof. Polymers may also be insulative or inherently electrical conductive, or any combination of both. Polymers may comprise single or multiple layers as a basecoat underneath a CNT coating, or a topcoat above a CNT coating, or combination of the basecoat and the topcoat forming a sandwich structure. A fluoropolymer containing binder, which is a solution of one fluoropolymer or a blend of fluoropolymers, which may be formulated with additives, is applied onto a carbon nanotube-based transparent conductive coating at nanometer level of thickness on a clear substrate such as PET and glass. The fluoropolymers or blend can be either semi-crystalline (with low level of crystallinity) or amorphous, preferably to be amorphous with low refraction index. Binder coating thickness can be adjusted by changing binder concentration, coating speed and/or other process conditions. This binder coating significantly improves optical transparency, and also maintain or increases conductivity of the CNT-based coating. With other benefits such as abrasion, thermal and moisture resistance, this binder coating and the resulting products is used for display and electronic applications.

Photonic crystal mirrors for high-resolving power fabry perots

A Fabry-Perot cavity comprised of three-dimensional photonic crystal structures is disclosed. The self-assembly of purified and highly monodispersed microspheres is one approach to the successful operation of the device for creating highly ordered colloidal crystal coatings of high structural and optical quality. Such colloidal crystal film mirrors offer high reflection with low losses in the spectral window of the photonic band gap that permit Fabry-Perot resonators to be constructed with high resolving power, for example, greater than 1000 or sharp fringes that are spectrally narrower than 1.0 nm. The three-dimensional photonic crystals that constitute the Fabry-Perot invention are not restricted to any one fabrication method, and may include self-assembly of colloids, layer-by-layer lithographic construction, inversion, and laser holography. Such photonic crystal Fabry-Perot resonators offer the same benefits of high reflection and narrow spectral band responses available from the use of multi-layer dielectric coatings. However, the open structure of three-dimensional photonic crystal films affords the unique ability for external media to access the critical reflection layers and dramatically alter the Fabry-Perot spectrum, and provide means for crafting novel laser, sensor, and nonlinear optical devices. This open structure enables the penetration of gas and liquid substances, or entrainment of nano-particles or biological analytes in gases and liquids, to create subtle changes to the colloidal mirror responses that manifest in strong spectral responses in reflection and transmission of the collective Fabry Perot response.

Gas liquid distributor with incrustation sediment function

The invention discloses a gas-liquid distributor with begrime function. It comprises a chassis, a bell cap, a begrime element and disperse oar. Wherein, said bell cap is mounted above the begrime element via the support element; the begrime element is mounted on the chassis which comprises a inner screen component, a outer screen component, a cover board and a chassis to form the annular space structure; stuffing or protective agent can be filled into annular space according to the demand; the inner cylinder formed by inner screen component is in the hollow cylinder structure; the part of chassis relative to the inner cylinder of inner screen component is on the open structure under which the disperse oar is mounted via the connection element. Compared to present technique, the inventive gas-liquid distributor integrates the functions of begriming and gas-liquid distribution, while ití»s reaction with begriming avoids significantly increase of pressure drop, the influence of begriming function on the gas-liquid distribution. And it can reduce the space of reactor, improve the processing ability of reactor and prolong the working period of activator. The invention can be used in variable gas-liquid fixed-bed reactor in the hydrogenation on the petroleum hydrocarbon.

Date Oct. 23, 1997A corrosion resistant steel cord for reinforcing rubber articles, particularly a belt and/or carcass of a pneumatic tire, has a residual compressive stress inside the twisting helix of each steel filament such that a ratio R1/R0 is less than one, where R0 is the radius of curvature of a helix in each helically formed steel filament obtained by untwisting of the cord and R1 is the radius of curvature of the helix after removal of a surface layer from the inside of the helix in the steel filament. The steel filaments have a tensile strength of 4,000-4,800 N/mm2. The cord does not have a wrapping wire around its outer peripheral surface and has either a single twisted construction obtained by twisting 3 to 6 steel filaments in an open structure having a space between adjacent filaments or a two-layer twisted construction obtained by surrounding a core of n=1-4 steel filaments with a sheath of n+(2-6) steel filaments in a rubber penetration structure having a space between adjacent filaments of the sheath or a three-layer twisted construction obtained by surrounding a core of a single steel filament with a first sheath of m=3-6 steel filaments and a second sheath of m+(2-6) steel filaments in a rubber penetration structure having a space between adjacent filaments of each sheath.
