Nanoparticles like silica or titanium dioxide can be incorporated into car paints to enhance their scratch resistance. These nanoparticles form a harder, more durable coating that is less prone to damage from everyday wear, such as road debris, minor impacts, or car washing.

Nanotechnology enables the creation of self-cleaning or hydrophobic coatings, often referred to as "lotus effect" coatings. These coatings repel water, dirt, and oil, causing liquids to bead up and roll off the surface rather than sticking. Nanoparticles, such as silicon dioxide (SiO2), form a water-repellent layer on the paint, reducing the need for frequent washing and keeping the car cleaner for longer.

Additionally, oleophobic coatings repel oils, making it harder for grease or other oily substances to stick to the car's surface.

Nanoparticles like zinc oxide and titanium dioxide are used to protect the car’s surface from ultraviolet (UV) radiation. These nanoparticles absorb or reflect harmful UV rays, preventing them from degrading the paint over time, which can lead to fading or peeling. This UV protection extends the lifespan of the paint and helps maintain the car’s original color and finish.

Anti-corrosion nanocoatings can be applied to the car’s body to prevent rust. Nanoparticles in the coating form a protective barrier against moisture and oxygen, which are the primary causes of corrosion. These coatings are especially useful in areas where cars are exposed to harsh environmental conditions like salty roads or humid climates.

Some nanocoatings can be infused with antibacterial and antimicrobial agents, such as silver nanoparticles. These coatings can be applied to the interior or exterior surfaces of cars to reduce the growth of harmful microbes, contributing to cleaner, more hygienic surfaces, especially in high-touch areas like door handles, dashboards, and seats.

Nanoceramic coatings with infrared (IR) reflective properties can be applied to car windows or the body to reflect heat. This reduces the amount of heat absorbed by the car, improving thermal insulation and keeping the interior cooler in hot climates. This application is particularly useful in reducing the load on air conditioning systems, improving energy efficiency, especially in electric vehicles.

Nanomaterials such as carbon black and silica nanoparticles are already widely used in tire manufacturing. These nanoparticles reinforce the rubber, making the tires more resistant to wear and tear. The enhanced strength at the molecular level helps tires last longer, especially under extreme conditions like high-speed driving or rough terrain.

Nanoclays and carbon nano tubes can also be incorporated into tire compounds to improve mechanical strength, resulting in better resistance to abrasion and cuts.

Nanotechnology can improve the grip of tires on different surfaces, enhancing safety and performance. For example, silica nanoparticles are used to create better interaction between the rubber and the road surface. This enhances the tire’s ability to maintain traction in both wet and dry conditions, improving handling, braking, and cornering stability.

Graphene, a super-strong nanomaterial, is being explored to create tire treads that offer better traction without sacrificing durability.

Rolling resistance is a key factor affecting fuel efficiency, and nanotechnology helps to reduce it. By using silica nanoparticles in place of traditional carbon black, tires can achieve lower rolling resistance. This means less energy is required for the tire to rotate, leading to improved fuel efficiency and lower CO2 emissions.

Nanocomposites used in tire manufacturing make the tire both strong and lightweight, reducing the vehicle’s overall energy consumption, which is particularly important for electric vehicles (EVs) to extend their range.

By using nanomaterials like carbon nanotubes or graphene, tire manufacturers can create lighter tires without compromising strength or durability. Lighter tires reduce the vehicle’s overall weight, improving fuel efficiency and reducing wear on other vehicle components, such as suspension and brakes.
