Biodegradable Electrically Conductive Polycaprolacton-Based Composites Filled with Carbon Nanotubes

  • 3 Accesses

Electrophysical, morphological, rheological, and structural properties of new polymer composites based on polycaprolactone filled with single-walled carbon nanotubes are studied. It is shown that the percolation threshold for the developed composites is observed when the carbon nanotubes content is about 0.1 wt %. It is found that the degree of crystallinity of the composites increases by more than 60% compared to the pure polycaprolactone. The addition of carbon nanotubes to the polymer matrix leads to a decrease in the average size of crystallites, while their number increases essentially. It is shown that the developed composites can be treated by extrusion. Even when the content of carbon nanotubes is 1.0 wt %, the melt flow index is at least 0.5 g/10 min
