Characterization of free radicals created on polymer surfaces by plasmas
EMSL Project ID
1581
Abstract
The ability to modify polymer surfaces while retaining their bulk properties is very attractive for applications in wetting, adhesion, biocompatifility, sensing, wastewater treatment, heavy metals removal, and radioactive isotope removal. Plasma treatments cause chain scission and formation of free readicals on the surface. Part of the radicals are destroyed by recombinations with one another and/or by reactions with the atoms and molecules in the gas phase, leading to the formation of crosslinks, double bonds, and various functional groups. The radicals which are not able to react remain trapped in the polymer matrix and can be used for subsequent reactions with other molecules of different properties. This latter process will be explored in this program.
