Flexible Electrospun PET/TiO_2 Nanofibrous Structures for Dye-Sensitized Solar Cell (DSSC) Photoanodes

摘要

In this study, a solvothermal method was used to synthesize Titanium dioxide (TiO_2) nanoparticles in the presence of oleic acid (OA) and oleylamine (OM) as morphology-directing agents. Functional nanocomposite fibers composed of poly(ethylene terephtalate) (PET) mixed with OA-OM capped TiO_2 nanoparticles were developed by electrospinning process. The different variables that affect the stability of the process were optimized to produce uniform PET/TiO_2 nanofibrous mats without beads. The morphology and thermal stability of PET/TiO_2 nanofibers were investigated by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Thermo-gravimetric analysis (TGA).
