Modification of Glass Surface by Atmospheric Pressure Plasma
A Diffuse Coplanar Surface Barrier Discharge (DCSBS) operating in air at atmospheric pressure has been used to induce changes in the surface properties of glass. The contact angles of water drop on the surface of glass, which were measured by drop shape analysis, decreased markably with plasma treatment for 1 s. With the increasing of the plasma treatment time, the contact angles of the samples...
متن کاملMechanisms behind surface modification of polypropylene film using an atmospheric-pressure plasma jet
Plasma treatments are common for increasing the surface energy of plastics, such as polypropylene (PP), to create improved adhesive properties. Despite the significant differences in plasma sources and plasma properties used, similar effects on the plastic film can be achieved, suggesting a common dominant plasma constituent and underpinning mechanism. However, many details of this process are ...
متن کاملTime-related surface modification of denture base acrylic resin treated by atmospheric pressure cold plasma.
The changes of denture base acrylic resin surface properties under cold plasma and the relationships with time were investigated. Cold plasma treated the specimens for 30 s, 60 s, 90 s, and 120 s, respectively. Water contact angles were measured immediately after the treatment, 48 h, 15 days and 30 days later. Surface roughness was measured with 3-D laser scanning microscope. Candida albicans a...
متن کاملAtmospheric-pressure dielectric barrier discharge in He and He+O2 for surface modification of polymers
This paper provides an analysis on the various plasma effects on polymers exposed to atmospheric-pressure DBD. Homogeneous diffuse DBD, in symmetrical electrode configuration, working in He and He+O2 is used. The discharge is characterized by electric parameters measurement, whereas the surface is analyzed using contact angle measurement and XPS. The surface modification depends on the level of...
