The intrinsic hydrophobic nature of polymer tubes limits their applications in biomedical and mechanical fields. In this paper, homogeneous hydrophilization on the inner surfaces of polytetrafluoroethylene tubes was realized by directly inserting a flexible atmospheric cold microplasma jet (FμPJ) into the tubes. The water contact angle, surface morphologies, and chemical compositions of the treated inner surfaces were investigated to characterize the plasma hydrophilization. Results demonstrated that the wettability of the inner walls of the tube was well improved and the wettability could be retained at a low value even after 30 days of storage. Notably, homogeneous hydrophilization was achieved along the axial and circumferential directions of the tube. The results indicated that FμPJ shows great potential for uniform inner surface modification of polymers tubes.

使用柔性大气冷微等离子体射流在聚合物管内壁上进行均质表面亲水化

聚合物管的固有疏水性限制了它们在生物医学和机械领域的应用。在本文中，通过将柔性的大气冷微等离子体射流（FμPJ）直接插入到聚四氟乙烯管的内表面中，实现了均质的亲水化。研究了处理后的内表面的水接触角，表面形态和化学组成，以表征等离子体亲水化。结果表明，即使在储存30天后，管内壁的润湿性也得到了很好的改善，并且润湿性可以保持在较低的水平。值得注意的是，沿着管的轴向和圆周方向实现了均质的亲水化。
