Abstract
The article summarizes the results of the studies performed at the Institute of Chemical Physics, Russian Academy of Sciences, devoted to development of scientific foundations of adding nanosized particles of organic or inorganic photoactive compounds into polymers for production of new polymer nanocomposites of optical application. It is shown that luminescent europium complexes and photochromic indoline spirooxazines can be added to polymer matrices in the solubilized state at a threefold concentration compared to the process without Pluronics. The effect of an increase in the functional activity of solubilized luminescent europium complexes added to polymer compositions of various structures is discovered, which is related with a decrease in the size of aggregates of europium complexes at their solubilization by Pluronics. The solubilization by Pluronics exerts a sharp influence on the maximal content of indoline photochromes in the polymer matrix; the content of the colored form of photochrome in the 3D-crosslinked acryl matrix increases fourfold. This effect is related to both the decrease in the sizes of photochrome aggregates during solubilization and the plasticization of the polymer matrix by Pluronics.
