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.

Composite carbon nanotube structures

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.
