Abstract:
Thermoplastic polyurethane (TPU) nonwoven has good mechanical properties for use in biomaterial. However, its inherent hydrophobic nature restricts its application. In this study, atmospheric pressure plasma treatment with He and N 2 gases was employed to TPU nonwoven material to improve the surface hydrophilicity while retaining the hydrophobicility on the back side of the material. The surface wettability was measured by water contact angle analysis, and the surface chemical composition was analyzed by X-ray photoelectron spectroscopy (XPS). The surface morphology was examined using scanning electron microscopy (SEM). The experimental results reveal that oxygen-containing groups such as C–O and O–C=O are generated on the plasma-treated TPU surface, leading to improved wettablility of the material.
