The Production of Core-Shell Structure Carboxylated Carbon Nanotubes/Polypyrrole Composite Materials in Different Reaction Media and Further Investigation on their Core-Shell Structure

Abstract:

In this paper carboxylated carbon nanotubes/polypyrrole composite (CNTs/PPy) was synthesized in different surfactants aqueous under sonication. Carboxylated CNTs was synthesized in hydrogen nitrate by ultrasonic method and coated by PPy. The synthesized CNTs/PPy in different surfactants was evaluated by Fourier transform infrared spectrometer (FT-IR) and transmission electron microscope. The FT-IR patterns illustrate that CNTs were successfully doped by PPy. The morphology of CNTs/PPy synthesized showed on the transmission electron microscope images. The composite materials sythesized without surfactant are easy reunited. It is also found the surface of CNTs/PPy synthesized in cetyl trimethyl ammonium bromide (CTAB) is smoother than that in other surfactants. The coating effect is better with thicker coating layer. The higher magnification of HRTEM images show the PPy was deposited directly on the surface of carbon nanotubes. The final products are the ordered coaxial composite with well-defined core-shell structure.
