Abstract:
1. A method for producing a molded body, said method comprising: providing a film comprising a thermoplastic plastic and having a film thickness D ranging from 1 μm to 1000 μm; irradiating the film with ionizing radiation, to produce an irradiated film having irradiated regions having a radiation dose; thermally reshaping the irradiated film into a molded body so that a correlation between the radiation dose and the irradiated region is not lost and generating at least one hollow structure, wherein a temperature of the thermal reshaping remains below the melting temperature for the thermoplastic plastic, wherein the at least one hollow structure comprises: removing the irradiated regions, to create pores having a diameter δ from about 10 nm to about 10 μm in the molded body, and removing the molded body from a mold.
