摘要: Abstract In this study, surface modification of a silane-crosslinked polyethylene (Si-XLPE) compound was carried out by gliding arc atmospheric plasma. Samples were exposed to the plasma for different durations and plasma-induced alterations surfaces comprehensively assessed. Surface chemistry evaluated initially via Fourier transform infrared spectroscopy (ATR-FTIR) energy-dispersive X-ray (EDX) analysis. morphology investigated atomic force microscopy (AFM) field emission scanning electron (FESEM). For calculating free energy (SFE), contact angle measurement (CAM) performed. order have accurate details on morphology, photoelectron (XPS) Grazing Incidence Diffraction (GIXRD) analysis conducted, respectively. Results revealed that method doubled amount oxygen nitrogen surface, indicating formation polar chemical components surface. Moreover, could change considerably selective etching impacting roughness. Furthermore, it observed improved crystallinity some extent also increased SFE drastically. Si-XLPE has then proved be an effective technique during which noticeable improvement in wettability occurred.
