Plasma-Induced Hemi-Wicking on Sanded Polymer Surfaces

In this paper, a plasma-induced hemi-wicking phenomenon observed on hydrophobic sanded polymer surfaces, polypropylene (PP), polyethylene terephthalate (PET) and (PE) is reported. An atmospheric-pressure argon plasma jet was used to treat limited area of the carefully surfaces induce phenomenon. Such triggered by activation different from traditional type, which achieved purely surface topography. Surface analyses X-ray photoelectron spectroscopy (XPS) water contact analysis (WCA) show that combination sanding treatment increased oxygen-to-carbon ratio, highly beneficial for hydrophilicity. The shear stress tests can enhance 125%, 95%, 296% PP, PET, PE, respectively. study shows newly developed technique combining processing polymers could be potentially useful method in future industry applications.
