  • Patent number: 11866839
    Abstract: A process for making a carbon nanotube structure includes forming a composite by depositing or growing carbon nanotubes onto a metal substrate, and infusing the carbon nanotubes. In other aspects, a method of making a wire, includes coating carbon nanotubes on a wire, and electroplating the carbon nanotubes. In still other aspects, a method of making a conductor includes growing or depositing vertically aligned carbon nanotubes on a sheet. Yet still, a method of making a cable includes forming multiple composite wires, each composite wire formed by depositing or growing carbon nanotubes onto a metal substrate, and performing a metal infusion of the carbon nanotubes. The method also comprises combining multiple finished composite wires or objects to make large cables or straps.

  • Patent number: 10570541
    Abstract: Carbon nanotube threads are coated with a coating solution such as dimethylformamide (DMF), ethylene glycol (EG), polyethylene glycol (PEG), PEG200 (PEG with an average molecular weight of approximately 200 grams per mole (g/mol)), PEG400 (PEG with an average molecular weight of approximately 400 g/mol), aminopropyl terminated polydimethylsiloxane (DMS 100 cP),polymide, poly(methylhydrosiloxane), polyalkylene glycol, (3-aminopropyl)trimethoxysilane, hydride functional siloxane O resin, platinum (0) -1,3-divinyl-1,1,3,3-tetramethyl-disiloxane, moisture in air, acetic acid, water, poly(dimethylsiloxane) hydroxy terminated, (3-glycidyloxypropyl)-trimethoxysilane or a combination thereof. The coated carbon nanotubes may be used to stitch in a Z-direction into a composite such as a polymer prepreg to strengthen the composite. The stitching may occur using a sewing machine.

  • Publication number: 20020170290
    Abstract: A multi-dimensional, micro-electromechanical assembly and the method of fabricating same. The invention enables an assembly of three-dimensional (3D) microelectromechanical systems (MEMS) using surface tension or shrinkage self assembly. That is, the invention provides a surface tension self assembly technique for rotating a MEMS element with a controlled amount of deformation to a selected angle out of the plane of a substrate. In accordance with the inventive method, multi-dimensional, micro-electromechanical assemblies are fabricated by providing a phase change material on at least one substantially planar structure mounted in a first orientation. A phase change is induced in the phase change material whereby the phase change material changes from a first state, in which the structure is disposed in the first orientation, to a second state, in which the structure is disposed in a second orientation. The MEMS elements may be fabricated using conventional surface micromachining techniques.
