Looking at the rate of hardware development, we are at the point of a new era of customer behaviour where the potential for the mobile industry appears infinite.
And yet this new world can all come crashing down at the slightest touch of water, rain or humidity.P2i has developed an vague innovation nano-coating technology which changes the surface properties of smartphones and tablets, protecting them from electrochemical radiation and water damage brought on by everyday usage. As a commercially successful technology provider, the company introduced the first profitable 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. Properties: · Turbo engines and modern co-generative systems were used because of the Multilayer constructions, ceramics, temperatures unaffected, thermal shock, eroding’s and erosive wears and frittings etc.· ZrO2 based current blocks coatings were applied.· Hot parts defences were related to useful conditions turbo engines by Monolayer protections and vitro ceramics.
· Mono and multilayers defense, complex alloys, temperatures unaffected, corrosive and erosive wear, liquid metal contact resistant.· Integrating nanomaterials onto the wrapping surface to improve especially the barricade properties.· Using nano-thin coating (polymer + nanoparticles) can benefit us to provide greater barricade performance.
· Vaccum-deposited aluminium coating plastic films were there.· Coating of surface of glass and beverage flask (bottles, jars) with organosilanes are done. Nano coating plasma production Nanocoating on Mobile Phones Nanocoating on VehiclesMerits : · Resilient to temperature.· Water-resistant.· Unseen to human eye.· Has a high level of abrasion resistances.
· Prevents corrosion.· Breathable.· Coated surface can last approximately till 25 years.· Easy to clean.
· Provides a maintainable 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. Nano-coating with caustic soda steam 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. Acknowledgements This work was carried out under the sustainable infrastructure project in which nano-based wood modifications and their environmental impact were studied.
