Preparation and Characteristics of Stearic Acid/PEBOT(PSS)

摘要

Mixed Stearic acid and poly(3,4-thylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT7PSS) Langmuir-Blodgett films was successfully fabricated by the conventional vertical dipping method. Stearic acid and PEDOT/PSS was dissolved in chloroform and spread on subphase containing 0.04 wt% FeCl3. Conductive Y-type mixed LB films was successfully prepared under the condition of surface pressure 30 mN/m, pH 3.8, and 19°C. UV-Vis spectrum showed that well ordered layer-hy-layer fabrication of mixed films were obtained and thickness of single layer film was evaluated about 5nm. The morphology image of mixed LB film was observed by atomic force microscopy (AFM). The conductivity of mixed LB film was about 1.8×10~-5S/cm and the film showed sensitivity to NH3 at the same time.
