Nanoparticles and thin films made from nanoparticles are gaining recognition and use in various products and applications including displays, sensors and energy storage. These types of products often require well-controlled particle organization, density and film thickness to achieve optimal performance and efficiency.
Techniques that enable such control and precision during thin film formation are critically important in the development of new nanoparticle-based materials. The Langmuir-Blodgett deposition method offers a combination of controlled deposition, a wide range of substrates and usability in ambient conditions. In an LB deposition process, a nanoparticle suspension is first deposited at the air/water interface, then, the resulting film is compressed to the desired surface pressure and particle density and then transferred onto a solid substrate by dipping the substrate into and through the particle layer. The deposition can then be repeated to fabricate alternating layer structures or performed at different speeds and temperatures.
Anti-microbial coating is an example of a smart coating that uses silver nanoparticles. Silver nanoparticles are known for their anti-microbial properties and can be incorporated in many types of surface layers and coatings.
