LONG TERM APPLICATIONS
OF
NANOTECHNOLOGY
At present their are many long term applications in nanotechnology. Here i am going to give information about some applications.
1.MEDICAL IMPLANTS:
current medical implants, such as orthopedic implants and heart valves, are made of titanium & stainless steel alloys, primarily because they are biocompatible. Unfortunately, in some cases these metal alloys may wear out within the life time of the patient. Nanocrystalline zirconium oxide is hard, wear-resistant, bio-corrosion resistant & biocompatible. It therefore presents an attractive alternative material for implants.
2.WATER PURIFICATION:
Nano-engineered membranes could potentially lead to more energy-efficient water purification process, notably in desalination by reverse osmosis.
3.AIR, WATER & GAS FILTRATION:
Many researchers and corporations have already developed CNT-based air &water filtration devices. It has been reported that these filters can not only block the smallest particles but also kill most bacteria. This is another area where CNTs have already been commercialized & products are on the market now. Someday CNTs may be used to filter other liquids such as fuels & lubricants as well. A lot of research is being done in the development of CNT-based air & gas filtration. Filtration has already been shown to be another area where it is cost effective to use CNT.
4.FIBERS & FABRICS:
Fibers spun of pure CNTs have recently been demonstrated & are undergoing rapid development, along with CNT composite fibers. Such super-strong fibers will have many applications including body & vehicle armour, transmission line cables, woven fabrics & textiles.
5.CARBON NANO COMPOSITES:
CNTs have exponential mechanical properties, particularly high tensile strength & light weight. an obvious area of application would be in nanotube- reinforced composites, with performance beyond current carbon-fiber composites.
