The Preparation of PAN Composite TiO2 Nano-ACF and the Conditions Study


Article Preview

With its simple, easy operation, electrostatic spinning has become the most important and effective way on the preparation of nano-fibers. Through experiments, we identified the optimal conditions for the preparation of PAN nano-fibers composite TiO2 are: the spinning solution concentration is 12%, the angle is 5~8°, the spinning distance is 8cm, and the voltage is 12kV. The pre-oxidation largely determine the structure and properties of carbon fiber in the preparation of carbon nano-fibers. The temperature plays a decisive role on pre-oxidation. Through SEM、TG-DTA and FTIR, we explore the best conditions for the pre-oxidation temperature is 280°C and the pre-oxidation time is 2h. After carbonization and activation, the characteristic peak of TiO2 appeared at 2θ=25.2°, 37.7°in the patterns of XRD.
