This work reports an investigation of the discharge characteristics of atmospheric dielectric barrier discharge (DBD) plasma in terms of I-V curves and Lissajous figures and their effect on the surface functionalities of electrospun silk/PVA nanofibers. The results show that the filamentary discharge is predominant at lower electrode gap (3 mm) and then significantly reduces at higher electrode gaps of 6 mm and 10 mm, respectively and in the applied voltage range of 11–17 kV. The silk/PVA nanofibers which are treated with 6 mm electrode gap shows good wettability, higher surface energy, higher tensile strength, young’s modulus values and improved anti-thrombogenic property. All these findings suggest that, although the silk/PVA nanofiber itself can be used in biomedical applications however, nanofibers plasma treated at 6 mm electrode gap shows better results in terms of physical and biological performances.

这项工作报告了大气介质阻挡放电 (DBD) 等离子体在 IV 曲线和 Lissajous 图方面的放电特性及其对电纺丝/PVA 纳米纤维表面功能的影响的研究。结果表明，丝状放电在较低的电极间隙（3 mm）下占主导地位，然后在较高的电极间隙（分别为 6 mm 和 10 mm）以及 11-17 kV 的施加电压范围内显着降低。用 6 mm 电极间隙处理的丝/PVA 纳米纤维显示出良好的润湿性、更高的表面能、更高的拉伸强度、杨氏模量值和改善的抗血栓形成性能。所有这些发现表明，虽然丝/PVA 纳米纤维本身可用于生物医学应用，但是，
