摘要:

在这项工作中,我们研究了使用介质阻挡放电(DBD)等离子体在两个不同的组件,一个使用的主要等离子体射流从传统的DBD和其他使用DBD等离子体射流转移的聚(二甲基硅氧烷)(PDMS)表面的处理。水的接触角(WCA)在等离子体处理时间的函数和老化时间的函数,以及PDMS样品的表面粗糙度的变化的演变进行了研究。我们还比较了两个等离子体的振动和旋转温度和第一次转移的等离子体射流的振动温度(T_vib)已被证明是较高的相比,与主射流。Tvib值的增加似乎是转移等离子体射流的粘附性能和表面润湿性改善的主要原因。振动温度的增加可能的解释。

英文摘要:

In this work we studied processing of poly(dimethylsiloxane) (PDMS) surfaces using dielectric barrier discharge (DBD) plasma in two different assemblies, one using the primary plasma jet obtained from a conventional DBD and the other using a DBD plasma jet transfer. The evolution of water contact angle (WCA) in function of plasma processing time and in function of aging time as well as the changes in the surface roughness of PDMS samples for both plasma treatments have been studied. We also compared vibrational and rotational temperatures for both plasmas and for the first time the vibrational temperature (T_vib) for the transferred plasma jet has been shown to be higher as compared with the primary jet. The increment in the T_vib value seems to be the main reason for the improvements in adhesion properties and surface wettability for the transferred plasma jet. Possible explanations for the increase in the vibrational temperature are presented.
