ABSTRACT: Dielectric barrier discharge
is used as a cheap technique for surface treatment of polycarbonate. The
discharge system is working in open air at atmospheric pressure. The treatments
are carried out at low discharge powers (1.5 and 2 W) for treatment time (2.5 -
15 min). The treated samples show decrease in the contact angle and increase in
the crystallinity, thermal stability and surface roughness. The effect of ozone
on the increase in the oxygen containing functional groups is discussed. The
treatment process shows effective limitation of the migration of bisphenol A
from the surface of polycarbonate due to the cross linking. Zero migration of
bisphenole A is recorded as the sample is treated for 7.5 min. The treatment
process is found to be very efficient with very low cost.
