Carbon nanotube thread Z-axis multifunctional stitching

A method for coating a carbon nanotube thread having an initial coefficient of friction, the method comprising:

• immersing a carbon nanotube thread in a coating solution to form a coated carbon nanotube thread, the coating solution being selected from the group consisting of DMF, DMS, AMSG, HPM, PAWG, PHGM, AMSG2, PPHAP, PGPMH, and PPA, where:
• DMF is dimethylformamide;
• DMS is an aminopropyl-terminated polydimethvlsiloxane;
• AMSG is a mixture of polvalkvlene glycol, (3-aminopropvl) trimethoxysilane, hydride-functional siloxane O resin, and platinum (0)-1,3-divinyl-1-1,1,3,3-tetramethyl-disiloxane;
• HPM is a mixture of hydride-functional siloxane O resin and platinum (0 )-1,3-divinyl-1,1,3,3-tetramethyl-disiloxane;
• PAWG is a mixture of polyalkylene glycol, (3-glycidyloxypropyl) trimethoxysilane, acetic acid, and water;
• PHPM is a mixture of polyalkylene glycol, hydride-functional siloxane O resin, and platinum (0 )-1,3-divinyl-1,1,3,3-tetramethyl-disiloxane;
• PHGM is a mixture of polyalkylene glycol, polv(methylhydrosiloxane), (3-aminopropyl)trimethoxysilane, and platinum (0 )-1,3-divinyl-1,1,3,3-tetramethyl-disiloxane;
• AMSG2is a mixture of polyalkylene glycol, (3-glycidyloxypropyl)trimethoxysilane, hydride-functional siloxane O resin, and platinum (0 -1,3-divinyl-1,1,3,3-tetramethyl-disiloxane:
• PPHAP is a mixture of polvalkylene glycol, poly(methylhydrosiloxane), (3-glycidyloxypropyl)trimethoxysilane, and platinum (0 )-1,3-divinyl-1,1,3,3-tetramethyl-disiloxane;
• PGPMH is a mixture of polyalkylene glycol, (3-glycidyloxypropyl)trimethoxysilane, Hydroxyl-terminated poly(dimethylsiloxane), acetic acid, and water;
• and
• PPA is a mixture of polyalkylene glycol, hydroxyl-terminated poly(dimethylsiloxane), and (3-aminopropyl -trimethoxysilane;
• and
• heating the coated carbon nanotube thread at a temperature from 50° C. to 230° C. to dry the coated carbon nanotube thread, the coated carbon nanotube thread having after drying a final coefficient of friction less than the initial coefficient of friction.
