Abstract
The present invention provides a method of making a carbon nanotubes fiber by providing a polyethylene terephthalate substrate; contacting the polyethylene terephthalate substrate with a polyvinyl alcohol polymer solution to form a polyvinyl alcohol polymer layer on the polyethylene terephthalate substrate; contacting the polyvinyl alcohol polymer layer with a carbon nanotube solution, wherein the carbon nanotubes solution comprises one or more carbon nanotubes; forming a nanotube layer on the polyvinyl alcohol polymer layer; delaminating the polyvinyl alcohol polymer layer from the polyethylene terephthalate substrate to release a composite fiber layer; stretching the composite fiber layer; and drying the composite fiber layer.
