Claim Text:
1. A method for producing a plastic substrate and a porous layer, the method comprising: forming the porous layer using a plasma process, the plasma process simultaneously bringing about structuring of the plastic substrate by an ion bombardment and coating of the plastic substrate; and forming a solid phase of the porous layer, wherein at least 10% of the porous layer comprises material of the plastic substrate, wherein a proportion by volume of pores is greater in a first region of the porous layer than in a second region of the porous layer, wherein the first region is located between the second region and the plastic substrate, wherein the porous layer has a thickness between 50 nm and 500 nm, and wherein the pores, on average, have a lateral extent between 20 nm and 200 nm.
