Abstract
Initial stages of polymer functionalization with different functional groups will be determined experimentally. Results will represent a breakthrough in understanding the complex mechanism involved at interaction of reactive gaseous species with polymer surfaces. For the first time, the polymer surfaces will be exposed to variable fluences or reactive plasma radicals and the evolution of various functional groups with increasing fluences will be determined without breaking vacuum conditions using our high-resolution XPS instrument. The fluences will be measured precisely using specially adopted laser-driven catalytic probes. The evolution of functional groups versus fluences will be determined separately for oxygen and fluorine atoms as well as NHx radicals. The sources of these species will be microwave-driven discharges at variable powers. Three sources will be mounted onto the treatment chamber employing oxygen, ammonia and tetrafluoromethane as working gases. Gases will be introduced into the discharge chambers through flow controllers and will dissociate to radicals upon plasma conditions. The radicals will then enter the processing chamber which will be pumped continuously to assure for a rapid transfer of radicals from the plasma region to the samples with reasonable loss due to recombination or association to parent molecules. The entire experimental setup will be UHV compatible so the concentration of gaseous impurities will be marginal. The project will employ experts in polymer and plasma science as well as experts in construction of custom-designed plasma systems, high-frequency plasma sources and surface characterization. The results will be published in reputable topical journals and we shall also write a monography on initial stages of polymer functionalization. Such a monography is currently not available since no group worldwide has performed experiments foreseen within this project. The dissemination will be through scientific meetings and media.
Significance for science
As stressed in the project description, our results will represent the first systematic experimental work worldwide on initial stages of functionalization of selected polymers upon exposure to neutral atoms or other radicals as revealed in the project description. The fluences of radicals will be determined rather precisely thus the results will be reliable. The results will be published in top-ranking specialized journals and summarized in a monography which will be not only a compulsory reading for a vast community of researchers working on modification of polymer surfaces, but will represent a unique source for theoreticians as well. As explained in the project description the theoreticians have launched few hypotheses about initial stages of polymer functionalization but the results obtained by their theory cannot be compared to the experimental ones since the appropriate experimental data do not exist. Our results will therefore provide theoreticians with precious experimental data and will enable theoreticians to upgrade their codes. This will be our important contribution to development of this scientific niche.
