Аннотация:The process of photooxidation of polytetrafluoroethylene composites with graphene by irradiation with monochromatic vacuum ultraviolet light at a wavelength of 123.6 nm from a resonant krypton lamp in the presence of air has been investigated by IR spectroscopy, X-ray photoelectron spectroscopy, and contact angle measurement. It has been shown that the introduction of small additives of graphene (1–10 wt%) into the polytetrafluoroethylene matrix leads to a significant decrease in the rate of the photodegradation process and, as a consequence, to improvement in the performance characteristics of the polymer under photooxidation conditions.
