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.
