Origin of Buckypaper and its perspective applications

     
Buckypaper is a macroscopic aggregate of carbon nanotubes (CNT) which is ultrathin, electrically conducting and 10 times lighter than steel while still being 250 times stronger. The tough material can be folded, cut with scissors, like notebook paper. Composed of tube-shaped carbon molecules 50,000 times thinner than a human hair, Buckypaper possesses unique properties enabling it to conduct electricity like brass or steel and disperse heat like metal or silicon.
In the 1980s a carbon atom arrangement called Carbon 60, or Buckminsterfullerene, was discovered that turned out to be twice as hard as diamond. The pattern of carbon atom links was found to be identical with the basic polyhedron that R. The flat-sheet hexagonal form of carbon could wrap around itself to create long hollow tubes. These nanotubes have a tensile strength 40 times greater than that of the carbon fibers currently used in aircraft. In 1985, a team of scientists at Rice University, while conducting an experiment examining how stars produce carbon serendipitously discovered a ball of 60 carbon atoms, which scientists named "Buckyballs." The naming came from the buckminsterfullerene, the 60 carbon fullerene. Buckypaper is the brainchild of professor Ben Wang, an industrial engineer at Florida State University who discovered the carbon nanotubes of Buckyballs would stick together and could be produced into a small film.
Buckypaper is created from carbon nanotubes, which can be magnetically aligned during fabrication. Carbon nanotubes are suspended in water. Then the suspension is filtered the onto a membrane support. After drying, the paper is removed from the support, leaving a free-standing paper.
Buckypaper can be implicated in military vehicles to make them lighter and stronger, to make transporting these vehicles to trouble areas faster and more efficient. Also, buckypaper in the future is predicted to be applicable as a large-scale electron-field emitter for flat-panel displays, as a thermal conductor for superefficient heat sinks and as high-current protective film for the exteriors of airplanes. Such film would allow lightning strikes to flow around a plane and dissipate without damaging it.                                                                                                                                              

Buckypaper Applications:
Buckypaper is used in airplane industry.
Buckypaper is used in military armor plating.
Buckypaper is used in biological tissues.
Buckypaper is used in LCD (computer and TV) screens.
Buckypaper is used in sensor technology.

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
