POLYACRYLONITRILE NONWOVENS FOR THE PRODUCTION OF CARBON MATERIALS SUPPORTING THE REGENERATION OF BONE AND CARTILAGE TISSUES

Abstract

The influence of the change in surface weight on the physical properties of oxidized polyacrylonitrile precursor nonwovens intended for the production of carbon materials used in tissue engineering was studied. Thermal insulation properties of the nonwovens and their behavior during incubation in phosphate buffered saline (PBS) were investigated. Initial carbonization tests showed that from the point of view of carbonization and further application of carbon materials, the most effective was the use of a surface weight of about 120 g/m2. At the same time, for the research conducted on the incubation of nonwovens in PBS, no significant change in the pH of the solution was found.
