摘要

聚环氧乙烷（PEO）类防污涂层的常压等离子体沉积（APPD）为减少生物污染以确保生物传感器的可靠运行提供了一种极具吸引力的方法。冷大气压等离子喷射器设计为在露天环境中工作。本文通过使用乙烯基醚前驱体的 APPD，展示了露天加工对类 PEO 涂层成分和性能的影响。露天环境抑制了聚合，表现在沉积率低、涂层中氧的掺入以及涂层在水中的不稳定性。通过适当的喷嘴设计和在空气含量较低的环境中沉积，涂层的成分和稳定性都得到了改善。所得的类 PEO 涂层对抗体溶液具有稳定的防污作用，并能抑制人类成纤维细胞的粘附。

Impact of open-air processing on atmospheric pressure plasma deposition of poly(ethylene oxide) coatings for antifouling applications

Atmospheric pressure plasma deposition (APPD) of poly(ethylene oxide) (PEO)-like antifouling coatings provides an attractive way to reduce biofouling for reliable biosensor operation. Cold atmospheric pressure plasma jets are designed to operate in open air. This paper demonstrates the impact of open-air processing on the composition and properties of PEO-like coatings by APPD with vinyl ether precursors. The open-air environment inhibits polymerization as indicated by low deposition rates, oxygen incorporation in the coatings, and instability of the coatings in water. The composition and stability of the coatings improve by appropriate nozzle design and by deposition in an environment with lower air content. The resulting PEO-like coatings are stable and antifouling for an antibody solution and inhibit adhesion of human fibroblast cells.
