Transparent, conductive, and ultrathin graphene films, as an alternative to the ubiquitously employed metal oxides window electrodes for solid-state dye-sensitized solar cells, are demonstrated. These graphene films are fabricated from exfoliated graphite oxide, followed by thermal reduction. The obtained films exhibit a high conductivity of 550 S/cm and a transparency of more than 70% over 1000−3000 nm. Furthermore, they show high chemical and thermal stabilities as well as an ultrasmooth surface with tunable wettability.

Polymer nanotechnology: Nanocomposites

Transparent electrodes are a necessary component in many modern devices such as touch screens, LCDs, OLEDs, and solar cells, all of which are growing in demand. Traditionally, this role has been well served by doped metal oxides, the most common of which is indium tin oxide, or ITO. Recently, advances in nano-materials research have opened the door for other transparent conductive materials, each with unique properties. These include CNTs, graphene, metal nanowires, and printable metal grids. This review will explore the materials properties of transparent conductors, covering traditional metal oxides and conductive polymers initially, but with a focus on current developments in nano-material coatings. Electronic, optical, and mechanical properties of each material will be discussed, as well as suitability for various applications.

PROBLEM TO BE SOLVED: To provide a yarn, ribbon and sheet of nanofibers; to provide a method for producing the yarn, ribbon and sheet; and to provide applications of the yarn, ribbon and sheet.SOLUTION: In some embodiments, a yarn, ribbon and sheet of nanotubes include carbon nanotubes. Specifically, such carbon nanotubes of the present invention provide the following unique properties and property combinations, for example: extreme toughness; resistance to failure at knots; high levels of electrical and thermal conductivities; high absorption of energy that occurs reversibly; up to 13% of strain-to-failure as compared with a few percent in other fibers with similar toughness; very high resistance to creep; retention of strength even when heated in air at 450°C for one hour; and very high radiation resistance and UV resistance even when irradiated in air.

L'invention porte sur des fils, rubans et feuilles de nanofibres, sur leurs procedes de fabrication, et sur des applications associees. Dans certaines executions les fils, rubans et feuilles de nanotubes comprennent des nanotubes de carbone presentant des proprietes ou combinaisons de proprietes uniques, telles que: une extreme tenacite; une resistance a la rupture des noeuds, une conductivite electrique et thermique elevee, une forte absorption reversible d'energie; un rapport elongation/rupture allant jusqu'a 13 % contre les quelques pourcents des autres fibres de tenacite similaire; une tres forte resistance au fluage; une conservation de la resistance meme chauffees a 450 °C pendant une heure; et une forte resistance au rayonnement et a l'UV meme lorsqu'irradies dans l'air. En outre ces fils de nanotubes peuvent etre files en fils d'un micron de diametre et retordus a volonte pour donner des retors doubles, quadruples ou de rang plus eleve. D'autres executions portent sur le filage de feuilles de nanofibres de largeurs arbitraires. D'autres executions enfin portent sur des applications et des dispositifs utilisant et/ou incluant les fils, rubans et feuilles de nanofibres de l'invention.
