Polypropylene Fibers Filled with Carbon Nanotubes: Mechanical Properties and Biocompatibility

There have been investigated the process of generating polypropylene fibers filled with carbon nanotubes, their mechanical properties and biocompatibility. It has been found that the increase in the content of carbon nanotubes in the fibers of PP-CNTs increases the viscosity of the melt and reduces the elasticity. Biocompatibility testing of the fiber of PP-BHT showed a nonmonotonic effect of the content of tubes for compatibility of the polymer matrix with living tissues. It has been revealed that the composite with CNT concentration of 1.0 wt. % causes the least disturbance of the living organism and the tissue reaction to the implant has a local aseptic character.
