This invention relates to flexible, transparent and conductive coatings and films formed using single wall carbon nanotubes and polymer binders. Preferably, coatings and films are formed from carbon nanotubes (CNT) 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 the enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or any combination of both. 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. Binder coating thickness can be adjusted by changing binder concentration, coating speed and/or other process conditions. Resulting films and articles can be used as transparent conductors for flat panel display, touch screen and other electronic devices.

The iron-based sintered sliding material comprises: a sintered structure which contains 10-50 wt. % copper and 1-15 wt. % carbon and has been formed by sintering a powder mixture obtained by mixing at least one of an Fe—Cu alloy powder containing copper in an amount which is the solid solubility or larger and is 5-50 wt. %, excluding 50 wt. %, and an Fe—Cu—C alloy powder containing copper in an amount which is the solid solubility or larger and is 5-50 wt. %, excluding 50 wt. %, and containing carbon in an amount of 0-5 wt. %, excluding 0 wt. %, with a graphite powder and at least one of a copper powder and a copper alloy powder; and graphite particles dispersed in the sintered sliding material in an amount of 1-14 wt. % or 3-50 vol. %.

Unique abrasive and/or thickening materials that are in situ generated compositions of precipitated silicas and silica gels are provided. Such compositions exhibit different beneficial characteristics depending on the structure of the composite in situ generated material. With low structured composites (as measured via linseed oil absorption levels from 40 to 100 ml oil absorbed/100 g composite), simultaneously high pellicle film cleaning properties and moderate dentin abrasion levels are possible in order to accord the user a dentifrice that effectively cleans tooth surfaces without detrimentally abrading such surfaces. Increased amounts of high structure composite materials tend to accord greater viscosity build and thickening benefits together with such desirable abrasion and cleaning properties, albeit to a lesser extent than for the low structure types. Thus, mid-range cleaning materials will exhibit oil absorption levels from an excess of 100 to 150, and high thickening/low abrasion composite exhibit oil absorption properties in excess of 150. Such an in situ, simultaneously produced precipitated silica/silica gel combination provides such unexpectedly effective low abrasion and high cleaning capability and different thickening characteristics as compared to physical mixtures of such components. Encompassed within this invention is a unique method for making such gel/precipitated silica composite materials for such a purpose, as well as the different materials within the structure ranges described above and dentifrices comprising such.
