摘要

The paper presents the production of electrically conductive composite materials based on polyaniline (PANI) and commercially available microfibrous textiles with a fiber diameter of 12–20 μm. The initial and final samples were characterized using FTIR spectroscopy, X-ray diffraction analysis, and scanning electron microscopy. It was found that a thin continuous layer of PANI forms on the fibers first, followed by the growth of particles with various morphologies that depend on the pH of the medium. Thus, in a strongly acidic medium, the particles are granular, in a weakly acidic medium they are nanofibers, and in an alkaline medium they are microspheres. As the acidity of the medium increases, the specific conductivity of the samples increases, and the resulting composite materials have high electrical conductivity values (up to 3∙10− 2 S/cm) and can be used in organic electronics for the creation of microbial fuel cells.
