Multiwalled Carbon Nanotube Yarn

Multiwalled Carbon Nanotube Yarn
This scanning electron microscope image shows nanotube yarn fibers drawn from a "nanotube forest." Nanometer and micron-sized yarn or fibers drawn from multiwalled carbon nanotubes can have tensile strengths comparable to or exceeding those of spider silk. Replacing metal wires in electronic textiles with these nanotube yarns could lead to important new functionalities, such as the ability to actuate (as an artificial muscle) and to store energy (as a fiber super-capacitor or battery).

The yarn's diameter is about 1 µm. The nanotubes from which it is being drawn are each about 10 nm in diameter.

Nanotubes Mimicking Gecko Feet

Nanotubes Mimicking Gecko Feet
The nanoscale structures on a gecko's foot enable it to cling to most surfaces. This scanning electron microscope image shows multiwalled carbon nanotubes attached to a polymer backing, an experiment designed to replicate the gecko foot's adhesive properties. The gecko's amazing ability to cling to vertical or inverted surfaces is due to the interaction between nanoscale structures on its feet and tiny crevices on the wall or ceiling. The soles of gecko feet are made up of overlapping adhesive lamellae covered with millions of superfine hairs, or setae, each of which branches out at the end into hundreds of spatula-shaped structures. These flexible pads—each measuring only a few nanometers across—curve to fit inside unseen cracks and divots on the surface. The combined adhesion of these millions of pads holds the gecko in place.

Aligned Multiwalled Carbon Nanotube Forest

Aligned Multiwalled Carbon Nanotube Forest
This scanning electron microscope image shows a wall of carbon nanotubes. Multiwalled carbon nanotubes are nested within each other. They exhibit extraordinary strength and unique electrical properties. Multiwalled carbon nanotubes are actually tubes nested within tubes. These cylindrical carbon molecules have extraordinary strength and important electrical properties, making them potentially useful for many applications in electronics, optics, and other areas of materials science, as well as architectural fields.
