Coating evaporation

There are three major processes for applying the silicon oxide coating evaporation, sputtering, and chemical plasma deposition. 

Generally, the binders have a low content of organic solvents (ca. 10%) and can be applied over a wide temperature and humidity range. Water and organic cosolvents used in clearcoats applied by wet-on-wet coating evaporate rapidly after predrying with convection or IR radiation.

As illustrated in Fig. 5.36, spin coating can be divided into four stages deposition, spin-up, spin-off, and evaporation (62,67). As in dip coating, evaporation may occur throughout the process. Initially, an excess of liquid is deposited on the surface, which is at rest or rotating slowly. In the spin-up stage, liquid flows... 

Template-directed assembly refers to the use of some templates (including synthetic templates and natural templates) to assembly preformed nanoparticle building blocks, forming sophisticated and complex architectures. Various methods are used including sol-gel, chemical vapor deposition, chemical vapor infiltration, atomic layer deposition, dip-coating, evaporation and deposition, LBL, sonochemical assembly and biological-assisted assembly. 

These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. These coatings soon form a thin layer of the protective oxide and do not deteriorate as do silver coatings. They are used to coat telescope mirrors and to make decorative paper, packages, toys. 

Emulsion polymerization also has the advantages of good heat transfer and low viscosity, which follow from the presence of the aqueous phase. The resulting aqueous dispersion of polymer is called a latex. The polymer can be subsequently separated from the aqueous portion of the latex or the latter can be used directly in eventual appUcations. For example, in coatings applications-such as paints, paper coatings, floor pohshes-soft polymer particles coalesce into a continuous film with the evaporation of water after the latex has been applied to the substrate.
