Work

The aim of the work is sintering new bionanocomposites and study of the influence of multi-walled carbon nanotubes on the structure and the features of the kinetics of low-temperature gas sorption by these composites, which is important for the development of bone replacement implants with porosity, biocompatibіlity, osteoconductivity and mechanical properties similar to human bone. In medicine, hydroxyapatite (Ca10(PO4)6(OH)2) is commonly used to fill bone defects due to its high biological activity, biocompatibility, and structural similarity to the bone mineral component. However, the weak mechanical properties of calcium phosphate ceramics do not allow using it in places of defects, where the implant is exposed to high mechanical loads. The possible solution to improve the mechanical properties of hydroxyapatite (HA) is to use carbon nanomaterials as an additive. Scientific results expected in project will be related to creation of new materials based on calcium phosphates with the additives of multi-walled carbon nanotubes. Such materials can be used in personalized medicine, high-tech medical care and in medical technologies. Information about the structure of the new composites including the porosity and kinetics of low-temperature gas sorption in its components (bioactive matrix of hydroxyapatite and functionalizing ceramics of carbon nanomaterials additives) will be useful for proposing the technology that improves mechanical properties of such materials. The task of the project is to create a technology of improving biomaterials based on calcium phosphates by intercalation of new carbon nanomaterials into composites for medical and biological purposes, which are used to regenerate bone tissue. The results of the project will be important for predicting and analyzing structure, porosity, kinetics of gas sorption and mechanical properties of calcium phosphate-based biocomposites with additives of multi-walled carbon nanotubes.
