Surface modification of polystyrene with atomic oxygen radical anions-dissolved solution
The O − water, generated by bubbling of the O − (atomic oxygen radical anion) flux into the deionized water.
The surface hydrophilicity,
surface energy, and
all are increased by the O − water treatments.
Particularly, it was found that some hydrophilic groups were introduced onto the polystyrene surfaces via the O − water treatment, increases the surface hydrophilicity and surface energy.
The O − water is also considered as a “clean solution” and easy to be handled at room temperature. Present method may potentially suit to the surface modification of polymers and other heat-sensitive materials.
