Název v původním jazyce

Mechanical reinforcement of Bioglass (R)-based scaffolds by novel polyvinyl-alcohol/microfibrillated cellulose composite coating

Popis výsledku v původním jazyce

The preparation and mechanical properties of Bioglass-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 andhaving 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 ledto 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.
