Abstract
AbstractTwo types of polypyrrol/molybdenum disulfide nanocomposites were prepared by means of in situ polymerization of the intercalated monomers. The nanocomposites were characterized by means of powder X‐ray diffraction, Fourier transformation infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. The charge transport properties of the nanocomposites were determined by four‐probe electrical conductivity measurement of pressed pellet samples. The relationship between the electrical conductivity at various temperatures and conformation of the polypyrrol/ molybdenum disulfide nanocomposites were investigated. Results indicated that polypyrrol took two kinds of conformation in the interlayer of MoS2. The electrical conductivity of the intercalation nanocomposites at room temperature was dependent on the conformation and stereo‐regular characteristics of the polypyrrol molecules in the MoS2 layers, it was mainly determined by the number of the active charge carriers in polypyrrol at −60°C. The intercalation of polypyrrol into MoS2 led to an increase in the electrical conductivity by six orders of magnitude.
