Self-Assembled Stratified Structure in Polyalkylthiophene-6 and Polyvinylcarbazole Blend Film
Layered films of polyalkylthiophene-6 (PAT-6) and polyvinylcarbazole (PVK) which are expected to be a photo-electronic device were fabricated from blend solution by self-assembly at only one casting process. Cross-section structure of the blend polymer films were observed by digital microscope and analyzed by using Energy Dispersive Spectroscopy (EDS) and FT-IR spectrometer. Stratified structure with component distribution along thickness direction was found to be self-assembly at the suitable casting condition. It was considered that the structure was controlled by the evaporation speed of solvent and properties of the solubility parameter and density of the polymer.
