CNT/Polymer Applications

The outstanding properties of carbon nanotubes makes them of potential use in controlling other nanoscale structures, which suggests they will have an important role in Nanotechnology Engineering. On this page you find current and potential applications of carbon nanotubes.

Super-strong body armour in sight

A new type of carbon fibre (see Fig. below), developed at the University of Cambridge, could be woven into super-strong body armour for the military and law enforcement.

The researchers say their material is already several times stronger, tougher and stiffer than fibres currently used to make protective armour.
The lightweight fibre, made up of millions of tiny carbon nanotubes, is starting to reveal exciting properties. [read more]

Nanotube networks cut polymer flammability

Researchers at the National Institute of Standards and Technology, US, and the University of Pennsylvania, US, have found that if carbon nanotubes in a polymer matrix form a “jammed network” structure they can act as more effective flame-retardant additives than nanoclay particles. The addition of nanotubes also improves the mechanical properties and electrical conductivity of the polymers. [read more]

Video sequences reveal how different additives affect the behaviour of a plastic material (PMMA) when heated under fire-like conditions. The top two rows show behaviour during heating, and the bottom shows the final residue. Unmodified PMMA (left) behaves like a liquid, bubbling vigorously and leaving almost no residue. Adding a tiny dash (0.5 wt percent) of single-walled carbon nanotubes (centre) nearly eliminated bubbling; the residue was slightly thinner than the original sample, and it had a smooth undulating surface. Numerous small "islands" formed during heating of the material with multi-walled carbon nanotubes (MWNTs) and vigorous bubbling was observed among islands. With continued heating, islands eventually coagulated, forming large islands separated by deep cracks. Image credit: NIST

Transparent conductive films containing CNTs

CNT-based transparent conductive films may be used as a replacement for the brittle and expensive indium tin oxide (ITO) coated films currently used in such products as touch screens, LCD displays, solar cells, and solid state (OLED) lighting. [read more]

Carbon Nanotube Radio for Communications and Medical Applications Available for Licensing from Lawrence Berkeley

National Laboratory Professor Alex Zettl and his team at Berkeley Lab have invented and constructed a fully functional, integrated radio receiver based on a single carbon nanotube (CNT). The nanotube serves simultaneously as all essential components of a radio -- antenna, tunable band-pass filter, amplifier, and demodulator—to convert an electromagnetic signal into a mechanical signal and then into an electrical signal amplified and demodulated to produce audible sound. The radio is several orders of magnitude smaller than previous radios due to the use of the nanotube’s electro-mechanical movement instead of a conventional radio’s electrical components.

(a) Schematic of the nanotube radio. Radio transmissions tuned to the nanotube’s resonance frequency force the charged nanotube to vibrate. Field emission of electrons from the tip of the nanotube is used to detect the vibrations and also amplify and demodulate the signal. A current measuring device, such as a sensitive speaker, monitors the output of the radio.
