Carbon nanotubes can also enable shorter processing times and higher energy efficiencies during composite curing with the use of carbon nanotube structured heaters. Autoclaving is the ‘gold standard’ for composite curing however, it comes at a high price and introduces part size limitations.
Nanotubes can be classified into two main categories: single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs), each with distinct characteristics and potential applications. Since their discovery in 1991, nanotubes have been the subject of intense research and development, with promising applications in fields such as electronics ...
The strength and flexibility of carbon nanotubes makes them of potential use in controlling other nanoscale structures, which suggests they will have an important role in nanotechnology engineering. [239] The highest tensile strength of an individual multi-walled carbon nanotube has been tested to be 63 GPa. [56]
Nanotubes may be used in body armor for future soldiers. This type of armor would be very strong and highly effective at shielding soldiers’ bodies from projectiles and electromagnetic radiation. It is also possible that the nanotubes in the armor could play a role in keeping an eye on soldiers’ conditions. [8]
Carbon nanotube–plasma polymer-based amperometric biosensors for ultrasensitive glucose detection have been fabricated. [14] Two amperometric enzyme biosensors were fabricated. One had single wall nanotubes and the other multi wall nanotubes, however, plasma-polymerized thin films (PPFs) were incorporated into both.
The polychiral s-SWCNTs enable a wide range optical absorption from visible to near-infrared (NIR) light, increasing the photo current relative to using single chirality nanotubes. To maximize light absorption, the inverted device structure was used with a zinc oxide nanowire layer penetrating the active layer to minimize collection length.
Polysaccharides have been successfully been used to modify carbon nanotubes forming stable hybrids. [48] To make carbon nanotubes soluble in water, phospholipids such as lysoglycerophospholipids have been used. [49] The single phospholipid tail wraps around the carbon nanotube, but the double tailed phospholipids did not have the same ability.
Silicon nanotubes and silicon nanowires can be used in lithium-ion batteries. Conventional Li-ion batteries use graphitic carbon as the anode, but replacing this with silicon nanotubes experimentally increases the specific (by mass) anode capacity by a factor of 10 (though the overall capacity improvement is lower due to the far lower specific ...
