This paper describes the He non-thermal plasma treatment of liquid impregnated cotton fabrics. The cotton fabrics were soaked in either H₂O, D₂O or ethanol after which they were placed in an atmospheric pressure parallel-plate DBD reactor. The influence of the used liquid in combination with the plasma exposure time was studied using OES, FTIR, XPS and SEM. The addition of (deuterated) water was found to aid more efficiently in the incorporation of polar functional groups onto the cotton surface in comparison to a pure He plasma treatment. The presence of H and OH species in the discharge also caused extensive etching of the surface, which led to the formation of microcraters. The impregnation with ethanol was responsible for the formation of a plasma-based thin film on top of the cotton substrate, which was characterized by a high content of C–C bonds and a smooth surface morphology. These results show that the soaking of cotton fabric prior to plasma exposure can help to more effectively alter its surface properties compared to a dry plasma treatment.

本文介绍了He非热等离子体处理的液体浸渍棉织物。将棉织物浸泡在H ₂ O，D _2中O或乙醇，然后将它们放入大气压平行板DBD反应器中。使用OES，FTIR，XPS和SEM研究了废液与等离子体暴露时间的关系。与纯He等离子体处理相比，发现添加（氘化）水可更有效地帮助极性官能团结合到棉花表面。放电中H和OH的存在也引起了表面的广泛腐蚀，从而导致了微坑的形成。乙醇的浸渍导致在棉底材上形成基于等离子体的薄膜，该薄膜的特征在于高含量的C–C键和光滑的表面形态。
