System dependent aspect, plasma polymerization

Because an electrode does not function as electrode in DC or alternating current high-frequency discharge, the electrode system could be kept outside a glass reactor (capacitive external electrodes) or a coil around a glass tube (inductively coupled external electrode) can be used to create plasma. These modes of coupling could be dealt as a factor in the system-dependent aspect of plasma polymerization, i.e., the basic plasma polymerization remains the same. 

Because of the system dependent aspect of plasma polymerization, there is no material that can be adequately described as the plasma polymer of a particular monomer, e.g., the plasma polymer of styrene, the plasma polymer of tetrafluoroethylene, and so on. The factors that influence the system dependent aspect of plasma polymerization are operational parameters, such as flow rate, discharge power, system pressure, and substrate temperature, and the design factors of the reactor, such as its size and shape, mode of electric discharge, and location of the substrate. 

A typical example of the system dependent aspect of plasma polymerization can be seen in the data that are derived from the... 

System Dependent Phenomena. Perhaps the most important aspect of plasma polymers is that their method of formation, plasma polymerization, is highly system dependent. For example, a monomer will not yield a well defined polymer, but a variety of polymers can be formed from a monomer depending on how plasma polymerization is used. This is definitely different from conventional polymerization. For instance, styrene can be polymerized by many different polymerization techniques, but the products can always be identified as polystyrene. This is because the polymerizations are essentially molecular processes, and, consequently, the chemical structure of the monomer is retained within the resulting polymer in a very predictable manner.
