Mass absorption
Mass absorption was determined for the best scaffolds obtained from PLLA. These scaffolds had the best internal morphology and mechanical properties suitable for cartilage. The results obtained were compared with suits obtained from PLLA obtained using PVP as a blowing agent. The highest absorbability (Fig. 9) was observed in scaffoldings obtained by the wet phase inversion method with a polymer nanofiber (545.2 ± 92.6%). Scaffolds obtained by wet (315.7 ± 7.2%) with PVP as a blowing agent showed less water absorption. The lowest through dry phase inversion (124.3 ± 12.1%).
