摘要

The present work describes a method for fabrication of novel luminescent polymer composites based on non-isocyanate polysiloxane urethanes containing phenyleuropiumsiloxanes of various structures as luminescent molecular fillers. A series of filled polymers was obtained and characterized, and the physicochemical, mechanical, optical, and thermal properties of film materials based on them were studied. It was found as a result of the investigations that the novel composite materials exhibit intense luminescence characteristic of Eu3+ ions, the excitation of which occurs mainly due to energy transfer from the β-diketone ligand. They are also characterized by high thermooxidative stability (Td5% = 230–270 °C). Analysis of thermal and mechanical properties of polymer composites made it possible to establish the main factors determinining the properties of novel composite UV-sensitive coatings.
