Abstract
A method of forming a particle film on a surface of a solid or liquid substrate involves contacting the substrate, in the presence of a gas, with a liquid medium containing a plurality of particles suspended therein. A liquid meniscus is thereby formed between the substrate and the gas. An edge of the liquid meniscus is moved relative to the substrate, so that said particles in the liquid medium form the particle film on the surface of the substrate.
Claims5
A method for producing a particle film by contacting a solid or liquid substrate with a particle dispersive suspension, and sweeping, spreading and moving the leading edge of a meniscus formed at the 3-phase contact line by atmospheric air or gas, substrate and suspension, thereby forming the particles assembled, wherein the particle density and the number of particle film layers are controlled by the traveling velocity of the leading edge of the meniscus, volume ratio of particles and liquid evaporation rate, using these as parameters.
