采用低压顺流微波等离子体在钛基体上存款了PPAAm和PPAAc薄膜。在超纯水中超声处理下测试膜对溶解的稳定性。占空比对平均功率的变化被应用于评估膜特性对等离子体条件的敏感性。强交联的且由此防水的PPAAm和PPAAc膜与相对低但对于生物医学应用而言足够的官能团密度相关。此外，一些相似的工艺参数和溶解稳定性之间存在的沉积等离子体聚合物薄膜制备微波和射频等离子体报道。
Low-pressure downstream microwave plasma was used to deposit thin water resistant PPAAm and PPAAc films on titanium substrates. Film stability against dissolution was tested under sonication in ultrapure water. Variation of duty cycle on mean power was applied to evaluate the sensitivity of film properties on plasma conditions. Strong cross-linked and therewith water resistant PPAAm and PPAAc films correlate with a relatively low but for biomedical applications sufficient density of functional groups. Furthermore, some similarity exists between process parameter and dissolution stability of deposited plasma polymer films prepared by microwave and reported for radio frequency plasmas.
