  1. Nano technology Nano coatings

  2. How Nano coatings make material wateproof “P2i’s coating is applied in a process called “plasma enhanced vapor deposition”. The process involves three steps. Step One: the item is placed into a chamber which is brought down to very low pressure. Step Two: Plasma activates the surfaces of the device making them ready to bond to the monomer which is applied as a vapor.  Step Three: Further plasma polymerizes the monomer forming a nano-coating layer over and within the product. The chamber is brought back up to room pressure and the item removed.” (P2i, 2013) P2i world leader in liquid nano coatings URL P2i, 2013) P2i world leader in liquid nano coatings URL

  3. How nano coatings make products fog resistant “The actual anti-fog coating itself is composed of polyvinyl alcohol, which is a hydrophilic compound that causes the individual droplets of condensation to disperse. Before it can go on to a surface, however, a base of four successive layers of silicon molecules are first applied via an atmospheric plasma process. These layers bond to one another, but also allow the alcohol to bond to them, ensuring the durability and hardness of the combined coating.”

  4. How nano coatings make material more flameproof. “The material is “nano,” or ultra-small, built up from layers of alternating positively and negatively charged polymers so thin that almost 50,000 would fit across the width of a human hair. Size has an advantage, Grunlan explained. Because these layers are so thin, the polymer liquid seeps deep into cotton fabric and onto each individual cotton fiber. Existing flame retardants, in contrast, simply settle on fiber bundles like armor and slow the spread of flames, but the fabric still burns and turns black. When the new nano coating is exposed to a flame, it expands slightly and stops the fire from igniting and burning the fabric — which remains white, except for the small area where the cotton directly touches the flame. “

  5. conclusion There are many uses of nanocoatings that improve society in ways such as making material waterproof, reducing fog, and making material flameproof.
