Summary

New dry-coating methods for preparing polymer thin films are proposed by the use of physical vapor deposition (PVD). According to the type of polymer material, the films can be vapor deposited with different strategies. Direct vapor deposition can be applied for such polymers as polyethylene or polytetrafluoroethylene that have weak intermolecular interaction. In general, polymer thin films are obtained by a vapor-deposition polymerization method, which evaporates monomer materials and produces polymer thin films by polymerization reaction on the substrate surface. Coevaporation of bifunctional monomers leads to stepwise reaction via polycondensation or polyaddition to obtain thin films of such polymers as polyimide and polyurea. This method can also be applied for preparing thin films of π-conjugated polymers. Another class of vapor-deposition polymerization utilizes chain-addition reaction to achieve radical polymerization of vinyl monomers. This method has advantages in obtaining higher degrees of polymerization and in enabling versatile molecular design. A surface-initiated vapor-deposition polymerization, which combines the self-assembled monolayer (SAM) with vapor deposition of monomers, is a unique method to grow polymer thin films that are chemically bound to the substrate surface. The solvent-free nature of PVD is convenient for the formation of nanometer-thick films and multilayer films that are sometimes required for device fabrication. Application of vapor-deposition polymerization for organic light-emitting diode is also described.
