A method for making a carbon nanotube film includes providing an original carbon nanotube film and an angle control unit. The original carbon nanotube film includes a plurality of carbon nanotubes joined end-to-end by van der Waals force, and the angle control unit defines a through hole. A first end of the original carbon nanotube film is converged to form a carbon nanotube wire structure and a carbon nanotube triangle structure having an open angle adjacent to the carbon nanotube wire structure. The carbon nanotube wire structure is passed through the through hole of the angle control unit. The carbon nanotube triangle structure is cut. The carbon nanotube film is also provided.

A composite implant comprising an injectable matrix material which is flowable and settable, and at least one reinforcing element for integration with the injectable matrix material, the at least one reinforcing element adding sufficient strength to the injectable matrix material such that when the composite implant is disposed in a cavity in a bone, the composite implant supports the bone.

A method for treating a bone, the method comprising: selecting at least one reinforcing element to be combined with an injectable matrix material so as to together form a composite implant capable of supporting the bone; positioning the at least one reinforcing element in a cavity in the bone; flowing the injectable matrix material into the cavity in the bone so that the injectable matrix material interfaces with the at least one reinforcing element; and transforming the injectable matrix material from a flowable state to a non-flowable state so as to establish a static structure for the composite implant, such that the composite implant supports the adjacent bone.

The invention relates to glass strands and glass strand structures coated with an electrically conducting coating composition which comprises (as % by weight of solid matter): 6 to 50% of a film-forming agent, preferably 6 to 45%, 5 to 40% of at least one compound chosen from plasticizing agents, surface-active agents and/or dispersing agents, 20 to 75% of electrically conducting particles, 0 to 10% of a doping agent, 0 to 10% of a thickening agent, 0 to 15% of additives. The invention also relates to the electrically conducting coating composition used to coat the said strands and strand structures, to their process of manufacture and to the composite materials including these strands or strand structures. Application to the preparation of structures and composite materials which can be heated by the Joule effect or which can be used for electromagnetic shielding.

Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.

Devices, systems and techniques are described for producing and implementing articles and materials having nanoscale and microscale structures that exhibit superhydrophobic, superoleophobic or omniphobic surface properties and other enhanced properties. In one aspect, a surface nanostructure can be formed by adding a silicon-containing buffer layer such as silicon, silicon oxide or silicon nitride layer, followed by metal film deposition and heating to convert the metal film into balled-up, discrete islands to form an etch mask. The buffer layer can be etched using the etch mask to create an array of pillar structures underneath the etch mask, in which the pillar structures have a shape that includes cylinders, negatively tapered rods, or cones and are vertically aligned. In another aspect, a method of fabricating microscale or nanoscale polymer or metal structures on a substrate is made by photolithography and/or nano imprinting lithography.
