在真空下热分解的聚氧化乙烯与辉光放电结合使用的存款聚氧化乙烯类等离子体聚合物膜。没有等离子体的蒸发允许沉积具有与原始PEO的化学组成非常接近的化学组成的膜，尽管具有较低的平均摩尔质量。在真空蒸发过程中应用等离子体导致膜内交联的增强，但以醚结构保留减少为代价。在血液蛋白（白蛋白、免疫球蛋白和纤维蛋白原）的粘附和促进凝血酶诱导的纤维蛋白原/纤维蛋白聚合级联方面，研究了血浆聚合物的非污染性质和促凝性。
Thermal decomposition of PEO under vacuum was used in combination with a glow discharge to deposit PEO-like plasma polymer films. Evaporation without plasma allows the deposition of films with chemical composition very close to that of the original PEO, albeit with a lower average of molar mass. The application of plasma during vacuum evaporation leads to enhancement of crosslinking within the films, yet at the expense of reduced retention of ether structure. Non-fouling properties and thrombogenicity of the plasma polymers were studied in terms of adhesion of blood proteins (albumin, immunoglobulin and fibrinogen) and promoting a thrombin induced fibrinogen/fibrin polymerization cascade.
