Influence of various preparation methods on percolation behavior of systems based on cross-linked polyurethanes and carbon nanotubes

Influence of various preparation methods on percolation behavior of systems based on cross-linked polyurethanes and carbon nanotubes

The features of conductivity and percolation behavior of systems based on cross-linked polyurethanes (CPU) and carbon nanotubes (CNT) depending on the preparation methods are studied by methods of impedance spectroscopy and optical microscopy. It is established, that introduction of nanosized laponi...
