We investigated by attenuated total reflection Fourier infrared spectroscopy the chemical behavior of macromolecules on the surface of polyurethane microporous film doped with silver nanoparticles at temperatures between 25 and 200°C. Silver nanoparticles interact with the urethane group and form a urethane-silver-urethane structure with a specific surface configuration and a higher resistance to temperature. Chemical transformations of the macromolecules on the surface of polyurethane film depend on both the silver nanoparticles concentration and temperature.
