Study Notes

Antimicrobial Paints

Silver nanoparticles mixed with paint can provide an antimicrobial coating solution.
These nanoparticles can inhibit crucial cellular functions in microbes and kill bacteria and fungi.
An eco-friendly process for synthesizing silver nanopowder uses a silica substrate with gum arabic, a biopolymer derived from the acacia tree.

Corrosion Resistance

Global cost of fighting corrosion is estimated at $2.5 trillion annually.
Nanoparticles can create highly effective alternatives to traditional industrial paints and coatings for corrosion resistance.
Graphene, a super-thin material made from carbon atoms, exhibits promising anticorrosive properties.
Graphene-based coatings showed a 62% improvement in scribe creep compared to control coatings, indicating significantly improved corrosion resistance.

Dust-Repellent Coatings

TiO2-based nanocoatings can effectively control dust and dirt when exposed to UV radiation.
These coatings improve the efficiency of solar panels by preventing dust and debris accumulation.
Swift Coat developed a nanoparticle delivery system to create dust-repellent coatings for solar panels.
The AIDA (aerosol impact-driven assembly) nanomaterial deposition method involves accelerating aerosolized nanoparticles at sonic speed through a nozzle to attach them to a substrate.
This method allows for control over coating porosity and thickness, reducing reflectivity and improving solar panel efficiency.

Benefits of Nanomaterials in Paints

Nanomaterials provide unique properties for paints, including antimicrobial, anticorrosive, and dust-repellent capabilities.
These benefits offer advantages across various industries, including automotive, aerospace, construction, and marine applications.
Benefits outweigh the costs, leading to longer-lasting and more efficient end products.
