Abstract
We studied the photoluminescence of MEH-PPV polymer films and a MEH-PPV/DND nanocomposite after exposure to gamma irradiation from a radioisotope source of cesium-137 with doses of 0.5–12.2 kGy for H2O and their relaxation processes after exposure to the maximum dose. Exposure to gamma irradiation leads to the formation of new structural units in MEH-PPV/DND, which are similar in structure to the structural units of the conductive PPV polymer. A microscopic model is proposed that describes the evolution of MEH-PPV/DND photoluminescence in the context of the formation of bonds between aliphatic radicals of polymers and the surface of detonation diamond.
