摘要： A system and process for producing doped carbon nanomaterials is disclosed. A carbonate electrolyte including a doping component is provided during the electrolysis between an anode and a cathode immersed in carbonate electrolyte contained in a cell. The carbonate electrolyte is heated to a molten state. An electrical current is applied to the anode, and cathode, to the molten carbonate electrolyte disposed between the anode and cathode. A morphology element maximizes carbon nanotubes, versus graphene versus carbon nano-onion versus hollow carbon nano-sphere nanomaterial product. The resulting carbon nanomaterial growth is collected from the cathode of the cell.

摘要： Disclosed are a multi-wall carbon nanotube (MWCNT) formed using arc discharge and a method for manufacturing the same. The carbon source of the anode and boron that is the doping source, are evaporated through arc discharge and then deposited on the surface of the cathode to form MWCNTs, and boron is evenly distributed in the multi-walls of the MWCNTs. Therefore, the outer diameter of the MWCNT is reduced, high thermal stability is secured, and the effect of improving the field emission characteristics can be obtained.

摘要： Methods for preparing a nanotube membrane for use in a pellicle membrane using dry printing are disclosed. Nanotube fibers are produced in a reaction vessel and dry sprayed onto a filter to form the nanotube membrane. The thickness of the nanotube membrane can be controlled by moving the reaction vessel and the filter relative to each other, or by further processing to reduce the thickness of the layer deposited onto the filter. This method reduces the number of process steps, reducing overall production time, and can also be used to produce larger membranes. The pellicle membrane can be formed with multiple layers and has a combination of high transmittance, low deflection, and small pore size. A conformal coating may applied to an outer surface of the pellicle membrane to protect the pellicle membrane from damage that can occur due to heat and hydrogen plasma created during EUV exposure.

摘要： A plurality of CNTs are drawn out of VACNTs so as to be continuous in lines and are bundled into a thread shape, and a temporary thread bundled into a thread shape is temporarily wound on the first winder. The first winder is then rotated about an axis along a feeding direction of the temporary thread to twist the temporary thread while the temporary thread is fed from the first winder.

摘要： A method of making a stretchable film structure is provided. An elastic substrate is pre-stretched in a first direction and a second direction to obtain a pre-stretched elastic substrate. A carbon nanotube film structure is laid on a surface of the pre-stretched elastic substrate. The carbon nanotube film structure comprises a plurality of super-aligned carbon nanotube films stacked with each other. The pre-stretching the elastic substrate is removed and a plurality of wrinkles is formed on a surface of the carbon nanotube film structure to form the stretchable film structure. The present disclosure also relates to the stretchable film structure obtained by the above method.

摘要： Copper-filled carbon nanotubes and methods of synthesizing the same are provided. Plasma-enhanced chemical vapor deposition can be used to synthesize vertically aligned carbon nanotubes filled with copper nanowires. The copper filling can occur concurrently with the carbon nanotube growth, and the carbon nanotubes can be completely filled by copper. The filling of Cu inside the CNTs can be controlled by tuning the synthesis temperature.
