Nano-Coating Principles: What Are They & How Do They Work?

Understanding "Nano" and Nanocoatings: Definition, Purpose, and Applications

The term "nano" is a prefix signifying one-billionth of any given unit. For instance, one meter consists of a billion nanometers.

Nanotechnology encompasses all activities at the nanoscale, spanning various fields such as chemistry, technology, and engineering. The core elements of nanotechnology are nanoparticles, typically measuring 100 nanometers or smaller. The main focus of nanotechnology involves manipulating and designing matter at this scale, which is approximately 1/80,000th the width of a human hair.

This technology finds applications in various industries, including medicine, engineering, chemistry, and agriculture. For example, nanoparticles are used in medical diagnostics and treatments and are anticipated to play a role in sustainable energy by offering environmentally friendly solutions. Nanotechnology is also extensively employed in manufacturing and industrial sectors to enhance the properties of end products.

In everyday life, nanotechnology extends the shelf life of food packaging, reduces the weight of electronic devices, enhances the UV resistance of sunscreens, strengthens artificial bones, and improves the durability of vehicle surfaces against environmental factors.

What Are Nanocoatings

Nanocoatings are ultra-thin layers developed using principles of nanotechnology. When applied to surfaces, these coatings impart various beneficial properties, including:

• Water and oil repellency
• UV resistance
• Resistance to scratches, impacts, mould, fading, and oxidation
• Prevention of bacterial growth
• Resistance to harmful chemicals

These properties enhance the functionality and longevity of treated surfaces, making nanocoatings widely used across different materials, products, and structures.

Advantages of Nanocoatings

Depending on the material, surfaces treated with nanocoatings gain several beneficial properties, including liquid and stain repellency, scratch resistance, and chemical durability. These enhancements allow consumers to use products more efficiently, extend the lifespan of their belongings or home/vehicle surfaces, and maximise the value of their purchases. Nanocoating-treated products are easier to clean and more resistant to damage, reducing the time and effort needed for maintenance. As a result, personal items and valuables remain in better condition for a more extended period, thereby increasing their overall value.

Hydrophobic Coatings and the Lotus Effect: Application of Nanocoatings

Hydrophobia, in this context, refers to the property of repelling water. Surfaces treated with nanocoatings become hydrophobic, repelling liquids and remaining stain-free.

The "lotus effect" is derived from the lotus flower, which, like the waterlily, has leaves that repel water and dirt. This natural hydrophobic quality is also observed in other plants, such as wheat and corn. The structure of nanocoatings mimics these plants, providing treated surfaces with similar water repellency and easy cleaning properties, known as the lotus effect.

Nanocoatings can be applied to a wide range of surfaces, including textiles, glass, ceramics, metals, wood, and natural minerals. They protect clothing and footwear from stains and enhance the surfaces of vehicles, wooden furniture, boat decks, and many other materials with hydrophobic properties and the lotus effect.

UV Protection: Preventing Surface Damage with Nano Coatings

Just as UV rays can damage human skin, surfaces are also vulnerable to UV exposure. Prolonged exposure to UV rays can cause discolouration, fading, cracking, disintegration, sunburns, breakage, and loss of flexibility—a process known as UV degradation.

Many natural and synthetic materials used daily are susceptible to UV degradation. Nanocoatings that offer UV protection are designed to shield surfaces, particularly those made of rubber, wood, and PVC, from sun damage.

When UV-protection nano coatings are applied to surfaces exposed to sunlight, this invisible layer acts as a barrier, preventing fading, wear, and cracking. These nanocoatings are commonly used on wooden furniture, textiles, leather, boat surfaces, and vehicle paintwork to protect against UV degradation.

Stain Repellency and Easy-to-Clean Properties: How Nanocoatings Help

Nanocoated surfaces repel liquids and dirt, preventing the formation of stains and making cleaning easier. Even substances that typically cause stubborn stains cannot penetrate the deeper layers of the surface due to the protective nanocoating layer, allowing them to slide off easily. The hydrophobic properties and lotus effect of nanocoatings prevent dirt from adhering to the surface, allowing for easy cleaning without the need for traditional methods.

Nanocoatings are widely used in textiles, car care, detailing personal belongings, and home surfaces. For example, suede shoes treated with a nano-textile protection product can be wiped clean even after exposure to dirt and mud. Similarly, nano vehicle surface protection products form a durable, long-lasting layer over paintwork, preventing stains and damage from rain, mud, lime, hard water, bird droppings, chemicals, and gravel.

Industrial Applications and Mechanisms of Nanocoatings

Nano coatings are utilised across various industries for the protective layers they create on different surfaces.

Nanocoatings protect fabrics against stains, fading, wear and tear, wrinkles, UV damage, and bacterial growth in the textile and retail industries. In the automotive and marine sectors, these coatings protect surfaces from liquids, moisture, and UV rays, thereby preventing oxidation, corrosion, and scratches. Nanocoatings are also used on furniture, home surfaces, and personal belongings due to their liquid and stain repellency, easy-to-clean properties, and resistance to chemicals and scratches. Compared to standard coatings, nano coatings offer more effective and long-lasting protection with a significantly reduced amount of product.

Nanocoatings consist of microscopic particles at the nanometer scale. This allows them to form a much thinner layer on treated surfaces than standard coatings, making the protective layer invisible to the human eye without altering the surface's texture or appearance. The nano-coating layer alters the surface energy of the treated material, endowing it with properties such as liquid repellency, stain resistance, ease of cleaning, and durability against various damaging factors. This prolongs the lifespan, enhances the usability, and increases the functionality and value of the end products treated with nanocoatings.
