    Abstract

    In this study, a series TiO2-doped–polydimethylsiloxane composite (PDMS-TiO2) were synthesized at constant amount of PDMS and different amount of TiO2 particles.  For this purpose, TiO2 structures were synthesized by the hydrothermal method. Morphology and chemical structure of the obtained TiO2 particles were investigated by scanning electron microscope (SEM), Energy Dispersive X-ray (EDX), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy techniques. Prepared particles were directly dispersed in PDMS wax with melted. The obtained composite structures were examined structurally by SEM, FTIR, and XRD spectroscopy techniques. The intense peaks at 13° and 16.5° visible in the XRD spectrum confirm the desired composite structure. For the pure PDMS structure, 0,523 and 1,740 KeV was observed for O2 and Si in the EDX spectrum. Peaks at 0.452 (Ka) and 4.510 KeV (Kβ) were observed for the composite structures. Then, the thermal properties of the composite structures obtained were investigated by DSC analysis. The study of the specific heat capacity of obtained products is attained by using a DSC. Depending on the amount of doped TiO2 particles, the specific heat capacity value increased significantly in PDMS-TiO2 composite structures. Specific heat capacity study' of TiO2- polydimethylsiloxane composites is original and opened a new area about PDMS.
