This proposal is concerned with a detailed study of the pulsed and continous wave (CW) plasma polymerisation of compounds that give polyethylene oxide (PEO)-like surfaces. Plasma polymerisation provides a one-step process to surfaces that have the potential to substantially reduce biological fouling of surfaces. These plasma polymerised surfaces are sometimes referred to as non-fouling and have significant technical utility. Although desposition of such surfaces from plasma is an active area of investigation, little attention has been paid to the mechanism(s) of polymer deposition from plasma.A novel collecting surface which incorporates a range of diagnostics (including a mass spectrometer) and is capable of ion energy modulation will be used to probe plasmas (ions and neutrals) of compounds that give rise to PEO-like surfaces. Changes in the nature of the gas-phase species will be monitored as a function of plasma power (duty cycle) and correlated with changes in the chemistry of solid-phase plasma products (XPS/SIMS). The role of ions in the deposition process is suspected to be important and by ion energy modulation it will be possible to reduce the energy of ions (or totally exclude ions) arriving at the collecting surface/mass spectrometer. This can be done without any perturbation to the plasma.
