AI Technical Summary

Benefits of technology

[0006]It is becoming increasingly popular for carbon nanotubes to be used to make composite materials. Carbon nanotubes can be composed of a plurality of coaxial cylinders of graphite sheets. Carbon nanotubes composited with metals, semiconductors, or polymers result in a composite material with qualities of both materials. Generally, the composite has a solid linear structure or a sheet-shaped structure. However, macro-scale carbon nanotube hollow structures and methods for making the same are not provided.

Problems solved by technology

Embodiment Construction

[0019]The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

[0020]Referring to FIG. 1, one embodiment of a carbon nanotube composite hollow structure 10 is provided. The carbon nanotube composite hollow structure 10 is a freestanding tube-shaped structure. The cross-section of the outline of the carbon nanotube composite hollow structure 10 along a direction substantially perpendicular to the length of the carbon nanotube composite hollow structure 10 can be rectangular, trapezoid-shaped, circle-shaped, or ellipse-shaped. The carbon nanotube composite hollow structure 10 includes a carbon nanotube composite layer 12 and a through hole 14.

[0021]The outline of the through hole 14 can be similar to the outline of the carbon nanotube composite hollow structur...

Abstract

A macro-scale carbon nanotube composite hollow structure includes a plurality of carbon nanotubes and a polymer. The carbon nanotubes are combined with each other via van der Waals attractive force. The polymer is at least partly attached to the carbon nanotubes. A method for making the carbon nanotube composite hollow structure includes the steps of providing a linear structure and a carbon nanotube structure including at least one carbon nanotube film or at least one carbon nanotube wire, wrapping the carbon nanotube structure around the linear structure to form a first carbon nanotube composite structure, applying a polymer liquid to the first carbon nanotube composite structure such that a second carbon nanotube composite structure is formed, and removing the linear structure from the second carbon nanotube composite structure.
