Rezumat

The development of regenerative medicine requires the use of scaffolds that are biocompatible and biodegradable materials. Scaffolds appear to be a porous material (sometimes with additive component of mineral salts such as calcium phosphate), which can be implanted into damaged tissues of human body. Depending on the type of tissues, scaffolds need to meet different requirements. Thus in order to treat bone fractures the scaffolds need to obtain certain porosity and mechanical properties [1], scaffold should obtain electron conductivity to be able to splice nerve tissue [2]. The materials which can used as scaffolds are chitosan, polycaprolactone, polylactide. Such polymers degrade over time and disappear from the body [1]. Graphene, graphene oxide and graphene foam, which are biocompatible material have been of great interest. [3] Scaffolds are obtained on the basis of such materials and the proliferation of structures is revealed [4]. We used a hydrothermal method to create scaffolds. Graphene oxide slurry obtained by Hummers method from Timcal powder (Timrex KS-15) was chosen as the basic substance. We have created highly porous materials which filled with polymers. The porosity of the material ranges from 500 to 1500 m3/g. The structural and mechanical properties can be changed depending on the material synthesis mode and its filling with the polymer. We have made attempts to implement calcium phosphate into such structures as well.   Acknowledgments This work was supported by Scholarship of the President of the Russian Federation under Project No. SP-1493.2016.4.
