Ways to change the physical properties of films by forming Langmuir films of non-modified metal oxide nanoparticles at air-aqueous interfaces

This webinar explores innovative methods to create stable Langmuir films of non-modified metal oxide nanoparticles (NPs) at air-aqueous interfaces, which are crucial for applications in nanotechnology such as semiconductors and solar cells. Traditionally, the high hydrophilicity of metal oxide NPs like SiO₂ or TiO₂ prevents stable film formation at air-water interfaces, often necessitating hydrophobic modification with surfactants or polymers. The session introduces an alternative approach using inorganic salts to stabilize non-modified NPs and discusses how mixing NPs of different sizes and types can tailor the physical properties—such as roughness and surface charge—of the resulting films.
