Nanometrix presents a new concept to make monolayers and ultra-thin films for nano electronic web processing. The novel method was designed ex novo to match with today's industrial production line standards. In this process, the gas-liquid interface natural properties like flatness, mobility and tension, together with other natural forces like gravity, are elegantly combined. The process was invented to cure a long lasting basic problem encountered with quasi-static monolayer instrumentations: self-organization. High speed hydrodynamics mass production cures defects in monolayers. Lipids, nano diamonds, quantum dots, platinum dots, carbon nanotubes, SiO2, TiO2, latex, PMMA, fluorescent, thermo- and photo-chromic beads (from one nanometer to 100 microns) were deposited onto meters long flexibles. As well, polymeric solutions were thinned down to meters long uniform ultra-thin films. Solid substrates to be coated can be rolls of metal foils, plastic films and rigid materials like glass sheets and wafers. Concomitantly to processing material, nano scale planerizing surfaces of rough substrates (plastic films like PET, PC, etc.) by liquid substrate entrapment can also be performed. Thinness meaning flexibility, a natural lead for flexible nano electronics web production is here clearly obtained. This provides today to flexible nano electronic web industry a friendly and enabling tool.
