Narrator: To improve the performance of structural materials, researchers at NASA Langley Research
Center have devised a novel Method of Depositing Metal Nanoparticles onto Carbon Allotropes
and compositions.
Dr. Joseph Smith: It's where you take, in this case, carbon nanotubes and you place
in a metal acetate, salt, something like silver acetate, and you just physically mix it together.
Then you just stick it in the oven and you heat it up at a particular temperature, in
this case 350 degrees.
Narrator: The heat decomposes the silver metal nanoparticles on to the entire length of the
carbon nanotube.
This method doesn't require the use of any reducing solvents, agents, or electrical currents,
it is not only quicker to produce, but also more green to manufacture.
Carbon Nanotubes have a distinct set of electrical characteristics. As a dielectric able to both
insulate and dissipate electrical energy.
Because of its unique set of properties, this method could be beneficial to a variety of
industries.
Mr. Ken Dudley: Potential applications for this range from tailor able materials, artificial
dielectric materials that have unique electrical properties, mechanical properties, and thermal
properties. To create new and novel antennas, filter devices, phase shifters, capacitive
devices for modern electronics. Then we also can use the materials for semiconductor devices
and advanced composite materials.
Narrator: NASA's Method of Depositing Metal Nanoparticles onto Carbon Allotropes. Your
opportunity to improve the thermal and electrical properties of your polymeric and structural
materials.
