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 کاملPlasma–surface interaction at atmospheric pressure: A case study of polystyrene etching and surface modification by Ar/O2 plasma jet
ion by atomic O from the polymer chain has been discussed by different research groups as the most important channel for both low pressure plasma and atmospheric pressure plasma RH þ O ! R• þ OH p 1⁄4 10 ; 10 ; 10 ; (5) where p is the estimated reaction probability for the tertiary, secondary, and primary carbon sites provided by Bhoj and Kushner. It can be seen that the tertiary H has the high...
متن کاملAluminium Surface Activation Using Atmospheric-pressure Plasma
Contact angles and Attenuated Total Reflection FTIR measurements were performed to study plasma activation of aluminium surface in air atmosphere using Diffuse Coplanar Surface Barrier Discharge plasma source. Two types of aluminium surfaces were used: i) industrially produced bulk aluminium samples; ii) thermally evaporated thin films of aluminium on glass (sets of 400 nm and 2 μm thickness). ...
متن کاملPlasma-Assisted Deposition at Atmospheric Pressure
In plasma-assisted deposition methods the activation energy necessary for the initiation of chemical reactions is transferred via charged particles. Due to this fact in many cases the process temperature can be kept small, if gas discharges at pressures below 1 hPa are used. On the other hand low pressure requires a great deal of vacuum equipment. Processes at atmospheric pressure are more favo...
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 ...
