Abstract
It was established that a wide structured photoluminescence band (350–700 nm) occurs in bulk specimens of polytetrafluorethylene and its composites with multi-walled carbon nanotubes as a result of thermal and mechanical impact during preparation. Five distinct components of spectra were identified as a manifestation of –C=O– bonds excitation and energy transfer from those bonds to polyenic π-conjugated chains of different lengths. Usage of carbon nanotubes in composites with different content provides quenching of photoluminescence while preserving the nature of irradiation centers. High-energy electronic irradiation leads to further development and redistribution of photoluminescence components.
