Originální abstrakt

The preparation and mechanical properties of Bioglasss-based porous scaffolds reinforced by a composite coating constituted by polyvinyl alcohol (PVA) and microfibrillated cellulose (MFC) are investigated. Samples produced by foam replication process and having nominally 90% of open porosity were coated by dipping into an aqueous solution of PVA and MFC. Tensile tests were conducted on samples according to a new testing methodology optimized for highly porous ceramics. The addition of PVA/MFC coating led to a 10 fold increase of the tensile strength of scaffolds. The reinforcing and toughening effect of the composite coating due to crack bridging and fracture of cellulose fibrils embedded in the PVA matrix was proved by SEM observations.
