Chemistry of Electrical Discharge Polymerization

Selective Incorporation of Perfluorinated Phenyl Rings during Pulsed Plasma Polymerization of Perfluoroallylbenzene

“…The approaches taken to achieve structural retention in the final plasma polymer fall into two broad categories: The first involves changing the physical characteristics of the reaction system such as reactor design, power, pressure, flow rate, , excitation frequency, , substrate temperature, bias, etc. Alternatively, the chemistry occurring within the reactor can be controlled by a judicious choice of precursor structure, carrier gas, reactant mixtures, and even substrate composition. , In reality, most investigations involve finding the optimum balance between physical and chemical parameters to yield the desired products. The most successful method to date has been pulsing the electrical discharge on the ms−μs time scales. , Here, in some cases, structural retention can be attributed to very low average powers, whereas for other monomers, two distinct reaction regimes are present which correspond to the duty cycle on- and off- periods.…”
