With a focus on innovation, nanotechnology has defined new frontiers in science, bringing higher level of applications to industrial sectors in general and the automotive industry in particular. The automotive industry contains a wide range of companies, which are busy researching, designing, manufacturing, and marketing transportation and heavy-duty vehicles to meet up-to-date consumer demands. Nanoparticles, quantum dots, porous materials, nanotubes, nanofibers, and whiskers, generally in the form of nanocomposites, provide the field with exclusive potential. Such nanomaterials as titanium dioxide, zinc oxide, tungsten disulfide, carbon nanotube, and silicon oxide have been reported in engines, bodies, paints, adhesives, fuel systems, tires, lubricants, and filters, playing an important role in improving the fuel consumption, environmental impact through CO2-free engines, safety, quiet cars, self-healing body, light-weight construction, wear reduction, surveillance control, sustainability, and comfort of produced automotive. Tires reinforced with nanoparticles for better abrasion resistance, coatings such as paints with greater scratch resistance and water repellent ability, additives for enhancing engine efficiency, anti-fog solutions for windshields, and structural plastic parts with improved mechanical performance are the most conspicuous nanoproducts available on the global market.
Nano-based products of the automotive industry are classified into the following subdivisions:
1. Anti-freezing and cooling radiator additives
2. Car body treatments including after care finish, convertible top sealant, paint sealant, polish sealant, glass cleaner, glass protective coating, glass polish, wheel sealant, visor sealant, metal surface modifier, self-cleaning coatings, and rain repellent solution
3. Car wash including car wash concentrate, car wash kit, car wash towel, cleaning solvent, insect remover, interior cleaner, leather sealant, microfiber wash, nano-cleaning solution, screen cleaner, textile cleaner, and wheel cleaner
4. Filters including air, coolant, oil, and fuel filters
5. Fuel additives and bike cleaners
6. Oil additives and revitalizants
