Coating technologies are a part of every industry, either in the producing process or the assembled product. Advanced surface treatments improve every aspect of the industrialized world.
Medical coatings make devised replacement prosthesis a fact. Without these specialized coatings the replacement body parts would corrode and become a foreign object actively refused by the body’s natural defense mechanism. Medical coatings fool the body’s defense system into ignoring the assembled part and extending the helpful life of the new part several times over. Coatings also optimise the bearing surfaces of joint replacements for wear resistance while prolonging toughness and fracture resistance. Joint replacement is a windfall for folk who otherwise would be in continuing discomfort and incapacitated due to early joint malfunction.
Nano technology deals with manipulating matter on a molecular scale and nano technology is both useful and questionable. On the problem of molecular self assembly, there are those that advocate doomsday scenarios spawned by self replicating molecular machines. Be that as it may. Nano technology is an emergent science that may have far reaching ramifications.
Nano technology coatings are extremely cutting edge and helpful in modifying the performance and properties of existing materials. For instance, the addition of certain nano particles can reinforce the mechanical properties of polymers. This results in a more flexible or firm material that may be a replacement for some light weight metals such as aluminium, which requires large energy consumption to extract from sea water.
Perhaps the most obvious application of nano coatings is the varied products released for cleaning and the manipulation of surfaces to reject contamination. One of the first nano products released rejected water on automobile windshields. It became extremely preferred and eventually was added to optional coatings available at auto washes to treat the whole vehicle.
Masonry buildings are liable to contamination and erosion from air borne contaminants. A coating composed of nano particles will effectively seal, reject water and pollutant particles. This ends in far less maintenance on the building and extends the life of masonry structures.
It will be interesting to experience the growth of nano technologies and coatings, So far we have only scratched the outer layer of possible uses, some of the developing technology may be beyond the remit of imagination.
