Sheet-like polyethylene terephthalate materials having slight surface roughness consisting of dendritic, plateau-like structures having a fissured, fractal edge, a process for their preparation by exposing the surfaces to UV radiation produced by the decomposition of excimers, and the use of polyethylene terephthalate films treated in this manner as a substrate for ferromagnetic thin metal layers.

Sheet-like polyethylene terephthalate materials having slight surface

Semicrystalline polymers are heat-sealed with metals under pressure and at a temperature between the glass transition temperature and the softening temperature of the polymer by prior exposure of the polymer surface to UV radiation produced by the decomposition of excimers in the wavelength range of from 120 to 400 nm and with an energy density below the ablation threshold.

Heat-sealing of semicrystalline polymers with metals

A method for working an oxide material, and preferably a ceramic oxide material, with a laser emission of an excimer laser and without the creation of damage layers includes pulsing the laser emission to be impinged on the material to be worked.
