  • 1. 1 Applications of Nanotechnology in Automobile Industry Steevan Sequeira Manipal Technologies Limited Abstract: The emergence of nanotechnology in th1980’s was caused by convergence of experimental advances such as the invention of the scanning tunneling microscope in 1981 and the discovery of fullerenes in 1985. Now the nanotechnology products are used in various fields such as medical, material science, automobile etc. In this topic the various applications of nanotechnology in the automobile industries have been discussed. INTRODUCTION Nanotechnology is the manipulation of matter on an atomic and molecular scale. Generally nanotechnology works with material, devices and other structures with at least one dimension sized from 1 to 100nm. Nanotechnology was begun 30 years ago. Nanoscience and Nanotechnology can be used across small things and can be used across all other science fields such as chemistry, physics, material science and engineering. Today’s scientists and engineers are finding a wide variety ways to deliberately make materials at the nanoscales to take advantage of their enhanced properties such as high strength, lighter weight, increased control of light spectrum and greater chemical reactivity. In engineering their applications are mainly found in fabrication, mechanics and infrastructure APPLICATIONS IN AUTOMOBILE INDUSTRY  Lotus Coatings  In Windshields  Reduction in weight of Vehicles  Better Batteries  Fuel Cells  Catalytic Converters  Reduction in Fuel Consumption etc. LOTUS COATINGS The lotus effect refers to the very high water repellence exhibited by the leaves of the lotus flower. Some nanotechnologists have developed treatment, coatings, paints and other surfaces that can stay dry and clean themselves in the same way as lotus leafs. Lotus coatings are composed of hydrophobic nanoparticles of silsesquioxanes containing adhesion promoter groups and low surface energy groups. When these coatings are applied to the vehicles they will cause the water to bead into small droplet and roll off the surface without getting the surface wet. These coatings also prevent the dust from adhering to the surface of the vehicles thus preventing the surface from corrosion. The paints made by this technology have a self-healing property. Ships and boats which receive such coat on their bottoms can not only move faster, but also fuel consumption as water repellent property reduces friction drastically.
  • 2. 2 IN WINDSHIELDS Another of the advanced applications of nanotechnology in vehicles involves the production of mirrors and side panels that are made out of nanoparticles. Being so they filter the rays of the sun, smoke and other pollutants in the atmosphere. The same technology allows radio and phone signals as well as sound waves to freely enter the cars so that occupants of the vehicles are not made oblivious to the world outside. The mirrors made up by this technology have higher stiffness and high transparency rate. By applying the nanoparticle coatings to the windshields the fog formation over them can be eliminated completely. Researchers are going on to produce coatings made up of silicon so that solar energy could be utilized directly from windshields. REDUCTION IN WEIGHT OF VEHICLES In contemporary cars, a large share of the vehicles weight is due to the weight of engine and transmission system of the vehicles. As a result, vehicles require more fuel to push forward such machines. Nonetheless with the advent of alloys, engines were made lighter somewhat but not them to make fuel efficient. With nanotechnology engines and parts were made much lighter, thus eliminating the need to consume more fuel just to push the vehicle forward. In this regard Carbon Nanotubes are used which have 100times lesser weight to that of the steel but are much stronger than that of the steel. Also weight of the vehicles can also be reduced by decreasing in the weight of the chassis this can be achieved by using cast aluminum alloys at near atomic levels. IN CATALYTIC CONVERTERS Catalytic converters made of nanotechnology use the nanomaterials to prevent the platinum from aggregation so that less platinum is required for each converter. The key development is to coat platinum nanoparticles with the porous silica layer. Because of its weak interaction with the platinum, the silica coating provides an energy barrier that holds the platinum in place even at very high temperatures, preventing aggregation and maintaining catalytic activity. Experiments show that the silica-coated platinum maintained its catalytic ability (about 7500 C) at much higher temperatures than uncoated platinum, which began to aggregate at temperatures as low as 3500 C. REDUCTION IN FRICTIONAL LOSSES In vehicles the major energy loss is due to the friction losses. By adding certain
  • 3. 3 nanomaterials like boric acid particles to the motor oils there will be reduction in the friction. The result can be 4-5% reduction in fuel consumption. ADVANTAGES  In automobiles nanomaterial coating can prevent the corrosive materials from corrosion.  They decrease the frictional, tear and wear losses thus they decrease the rate of fuel consumption.  They are extremely small and light weighted but are harder than materials like steel, iron etc.  Plenty of raw materials are available for the manufacture.  They are durable for number of years etc. DISADVANTAGES  Presently nanotechnology is very expensive as its production cost is high.  Some of the industries like steel and diamond production industries could be effected in adverse.  Impact of nanotechnology on the environment is still unknown. CONCLUSION  Though the nanotech products are expensive they increase the performance of the automobile tremendously.  Life of parts of the automobile will be increased  Maintenance of the automotive can be minimized.
