Introduction

Nanocoating
are coating that produced by usage of some components at nanoscale to obtain
desired properties.
Nanocoatings can be categorized as nanocrystalline, multilayer coatings with
individual layer thickness of nanometers.
Nanostuctured coatings offer great potential for various applications due to
their superior characteristics that are not typically found in conventional
coatings.

Smartphones and tablets are really just starting their integration into
the customer life. Looking at the speed of hardware development, reduction and
customer adoption, we are at the point of a new era of customer behaviour where
the potential for the mobile industry appears immeasurable. And yet this new
world can all come crashing down at the slightest touch of water, rain or
humidity.

P2i has developed
an indistinguishable innovation nano-coating technology which changes the
surface properties of smartphones and tablets, protecting them from
electrochemical migration and water damage brought on by everyday spills and splish-splashes.
As a commercially successful technology provider, the company introduced the
first moneymaking protective nano-coating process for high-volume industrial in
2011, protecting devices for Motorola.

 

History

 

As we have previously defined, nano
coatings are not a sealer, but rather it is a molecular adjustment
that offers a hydrophilic and easy to clean surface. The particles bond are
connected physically and chemically to the surface to give it complete
protection against costume, corrosion and other destructive elements.

 

What is nano-coating? 

When treating a metal plate the process raises
atoms from the material of the plate to a more planned supply of the metal and
its oxides on the surface of the metal, and sometimes a artificial upper layer
of graphene. The result is that the surface becomes super conducting to
plasmatic fields, allowing the plasma from the universal field to flow through
it.  The surface will test as having infinite resistance and nil
conductivity of matter state electric field flows. A metal in nano state will have about 5% less field
strength compared to it’s matter state, which is how it can become a magnet to
plasmatic field strength in the presence of other materials.

The spacing of the atoms and layers produced by
the nano coating method is a function of the process employed, and of the salts
and other elements in the caustic mix that is used by Mr Keshe clarifies
that hot acid method causes the most refined layering of atoms, tracked by cold
caustic and lastly by fire method (which is currently the least recommended).

 

 

 

 

 

 

Properties:

·       
Multilayer construction, ceramics,
temperatures unaffected, thermal shock, eroding and erosive wear, fritting, etc.
applied at turbo engines and modern co-generative systems.

 

·       
ZrO2 based current barrier coatings.

·       
Monolayer protections and vitro ceramics,
related to useful conditions turbo engines for “hot parts” defenses.

·       
Mono and multilayers defense, complex
alloys, temperature unaffected, corrosive and erosive wear, liquid metal
contact resistant.

 

·       
Incorporating nanomaterials onto the wrapping
surface (either the inside or the outside surface, sandwiched as a layer in a
laminated) to improve especially the barrier properties.

·       
Using nano-thin coating (polymer +
nanoparticles) can help provide greater barrier performance.

·       
Vaccum-deposited aluminium coating plastic
films.

·       
Coating of surface of glass and beverage flask
(bottles, jars) with organosilanes.

Merits
:

 

·       
Nanocoating are resistant to temperature
changes.

·       
Nanocoating is waterproof.

·       
Nanocoating are invisible to human eye.

·       
It is UV rays stable and has a high level
of abrasion resistance.

·       
It prevents corrosion.

·       
Nanotech coatings are breathable.

·       
The functionability of the coated surface
can last approximately 25 years.

·       
Nano coated items are easy to clean.

·       
It provides a sustainable protective
coating.

 

 

Demerits :

 

·     To be honest the
only disadvantage of SuperHydrophobic Coating is that it is bit costly (rather
complex in process) to manufacture the coating which means it sells at higher
cost.

Application

 

·       
Nanocomposite Materials: Nanoparticle
silicate nanolayer (clay nanocomposites) and nanotubes can be used as
reinforced filler not only to increase mechanical properties of nanocomposites
but also to impart new properties (optical, electronics etc).

·       
Nanocoatings : Surface coating with
nanometer thickness of nanomaterial can be used to improve properties like wear
and scratch-resistant, optoelectronics, hydrophobic properties.

·       
Hard cutting tools: Current cutting tools
(e.g. mill machine tools) are made using a sort of metal nanocomposites such as
tungsten carbide, tantalum carbide and titanium carbide that have more wear and
erosion-resistant, and last longer than their conventional (large – grained)
materials.

·       
Using nanotechnology based knowledge may
be produced more efficient, lightweight, high-energy density batteries.

 

 

Future Application

·       
A nanocoating that could possibly have the
ability to self heal.

·       
Textile surfaces which can remove surface
scratches and scuff marks, repel insects and decolorize red wine spills are
under development.

·       
Nanotechnology is being used to develop
‘sensorized’ garments with the ability to monitor body temperature and vital
signs.

 

 

Conclusion:

 

Increasing concern on the
durability of wooden buildings as well as environmental damage caused by wood
treatments requires a better understanding of the moisture transport in
exterior coated wooden claddings exposed to different climatic conditions. In
this work the influence of transparent nano- based surface treatments on the
moisture transport was presented. This preliminary study has demonstrated a
rather poor performance of the surface treatments. However, further studies and
experimental investigations are needed to modify coatings using appropriate and
advantageous nanoparticles.
