Abstract

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 irradiated regions in the film; thermally reshaping the film into a molded body and generating at least one hollow structure, wherein a temperature of the thermal reshaping remains below the melting temperature for the thermoplastic plastic; 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.
