Abstract
Composite materials based on poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] and titanium dioxide are used in the optoelectronic and chemical industries. A study of the behavior of chemical bonds in the composite and of the influence exerted by an inorganic additive on its properties is topical. The physical properties of the composites are analyzed by IR (infrared) spectroscopy. All the experiments are performed in an oxygen atmosphere at room temperature. The spectral characteristics of the composite in the mid-IR spectral range are examined and the spectral absorption lines are identified. It is shown that the introduction of titanium dioxide into the polymer matrix does not cause intense oxidation processes within the composite. It is found that the main absorption lines characterizing the vibronic properties of titanium dioxide are not subject to spectral shifts within the polymer matrix.
