Synthesis and structural characterization of polyaniline/mesoporous carbon nanocomposite
Original language description
In this work, a new nanocomposite in which polyaniline (PANI) is encapsulated in ordered mesoporous carbon (CMK-3 type) has been synthesized. The aniline monomer was introduced into hosts from the vapor phase to avoid the formation of PANI layers on theouter surface. The structure and morphology of the nanocomposite were characterized by X-ray diffraction (XRD), N2 adsorption=desorption, FT-IR and Raman spectra, high-resolution transmission electron microscopy (HRTEM), and thermogravimetric analysis (TGA). The results show that PANI is almost formed in the channels of CMK-3 and the nanocomposite retains the ordered mesostructure. Encapsulated PANI exhibits better thermal stability than pure PANI because of confinement effect in the channel system. Theconductivity of PANI=CMK-3 nanocomposite containing 8.4 wt% PANI is 0.78 S=cm at room temperature.

Syntéza a strukturní charakterizace nanokompozitů na bázi polyanilínu a mezoporézního uhlíku
Czech description
V práci byla popsána syntéza nového typu nanokompozitu, ve kterém je polyanilín syntetizován uvnitř pórů mezoporézního uhlíku (typ CMK-3). Struktura a morfologie byla charakterizována rentgenovou difrakcí, adsorpcí/desorpcí N2, FT-IR a Ramanovou spectroskopií, transmisní electrononovou mikroskopií (HRTEM) a ttermogravimetrickou analýou (TGA). Výsledky ukázaly, že PANI se tvoří téměř výhradně v pórech CMK-3 a nanokompozit si zachovává uspořádanou mezostrukturu.
