Popis:	Polyaniline/diatomite composite was prepared by the oxidation of aniline in the presence of diatomite, and this composite was characterized by Fourier transform infrared spectra, Fourier transform Raman spectra, UV‐VIS absorption spectra and wide‐angle X‐ray diffraction, as well as conductivity. The results of spectral analysis illustrate that polyaniline is not simply blended with diatomite. An interaction exists at the interface of diatomite and polyaniline, which may be associated with hydrogen bonds formed between the surface of diatomite with electronegativity and N–H bonds in the polyaniline macromolecule. The result of wide‐angle X‐ray diffraction shows that polyaniline has no effect on the crystallizability of diatomite, but conductivity of the composite containing 8% polyaniline has reached 2.8 × 10− 2 S·cm− 1 at 20°C.
