Abstract
Hybrid electrically conductive materials were obtained by the synthesis of a polyaniline-based conductive layer on fibrous matrices. Nonconductive nonwoven fabrics with fibers 0.5–13.5 μm in diameter were produced by electrospinning from solutions and melts of a number of commodity polymers. The influence of the surface properties of the initial matrices on the polyaniline synthesis process and electrophysical characteristics of the hybrid conductive materials was studied. It was shown that for highly hydrophobic matrices synthesis of the conductive layer occurs only on the upper layers of fibers, which causes much lower conductivity (10–4 S/cm and less) compared to wettable matrices, where synthesis occurs over the entire volume of the nonwoven fabric, and conductivity reaches 5 × 10–2 S/cm.
