| Summary: | Atmospheric pressure plasma is now being
widely developed for simple surface treatment process and
for fast medical tools sterilization. Plasma surface
modification involves the interaction of the plasma
generated excited species with a solid interface or coatings.
The previous vacuum plasma system is not applicable and
very costly. In the present project, we have developed the
high voltage power supply and atmospheric pressure
plasma using dielectric barrier discharge concept. The high
voltage power supply was developed using a simple 555
timer and car’s ignition coil. Then, we investigate the
plasma surface modification effect from the contact angle
measurement and evaluate the roughness using surface
profiler. We found that the contact angle decreased with
the exposure time and surface roughness changed when
exposed with atmospheric pressure plasma. It has been
understood that a film coating will be create on glass and
silicon surface when expose with atmospheric pressure
plasma system in water vapor environment. |
