- The plasma source ion implantation technique
was applied to modify the surface of ethylene-vinyl
alcohol (EVOH) film using various working gases. The
effects of the treated films were observed on the adhesion
efficiency and physical properties. The hydrophobic properties
of EVOH films were greatly enhanced after tetrafluoromethane-
plasma source ion implantation (PSII)
treatment. On the other hand, the higher hydrophilic properties
of EVOH films increased after oxygen-PSII treatment.
The results of X-ray photoelectron spectroscopy
showed that the improved hydrophobic or hydrophilic
properties of the film were closely related to the formation
of fluorine-containing functional groups (i.e., CF, CF2, and
CF3) or oxygen-containing functional groups (i.e., CAO,
C=O) on the modified surface. According to the result
observed by atomic force microscopy, the surface roughness
was not influenced on the change of contact angle.
Both the peel strength and oxygen barrier property were
improved in the case of CF4+O2-PSII-treated EVOH films.
As a function of aging time, the properties of modified
EVOH surfaces were maintained after PSII treatment using
CF4 and O2 at the energy level of -5 kV for 1 min. When
using PSII treatment, the properties of the EVOH surface
were controlled by working gas and treatment conditions.
