    • Plasma treatment apparatus and method for producing a polymeric substrate using an atmospheric pressure glow discharge plasma in a treatment space formed between two or more opposing electrodes connected to a power supply using a gas composition in the treatment space comprising a precursor and oxygen. A first layer of inorganic material is deposited on a polymeric substrate with a largest thickness (d3) of at least 100% of an Rt-value being defined as the maximum peak to valley height of the profile of the polymeric substrate measured substantially perpendicular to the surface of the polymeric substrate. A second layer of inorganic material is deposited on the first layer, wherein in the treatment space the oxygen has a concentration of 3% or higher, and the power supply is controlled to provide an energy across a gap between the two or more opposing electrodes of 40 J/cm2 or higher.
    • 一种等离子体处理装置和使用大气压辉光放电等离子体的聚合物基板的制造方法,该处理空间形成在使用包含前体和氧气的处理空间中的气体组合物与电源连接的两个或更多个相对电极之间。 第一层无机材料沉积在聚合物基材上,其最大厚度(d3)至少为Rt值的100%,其定义为聚合物基材的轮廓的最大峰谷高度基本上垂直于 聚合物基材的表面。 第二层无机材料沉积在第一层上,其中在处理空间中氧气具有3%或更高的浓度,并且控制电源以在两个或更多个相对电极之间的间隙上提供能量 40J / cm 2以上。
