METHOD FOR PRODUCTION OF LARGE AREA 2-DIMENSIONAL ARRAYS OF CLOSE PACKED COLLOIDAL PARTICLES

摘要

A monolayer (5) of non-amphiphilic particles is formed at a liquid-gas interface and is compressed on the liquid surface. The compressed layer is removed from the liquid surface (9) onto a substrate (11) and the substrate is dried. The said interface is preferably water-air. The monolayer may be, for example, of particles of polystyrene or a zeolite. One or more further monolayers may be built up.
