- W2564604456 abstract "Much attention has recently been paid to bioabsorbable polymeric materials, such as poly(L-lactic acid) (PLLA), in the field of orthopedics and oral surgery. For example, PLLA has extensively been used as resorbable bone fixation devices. Recently, hydroxyapatite (HA) micro-particles filled PLLA has also been developed to improve the bioactivity, elastic modulus and absorption rate of biomedical PLLA devices. Porous structures of PLLA and HA/PLLA composites have also been developed to improve osseous conduction so that these biomaterials can be used as scaffolds in tissue engineering for rejenerative medicine. Such porous materials may also be utilized as artificial bones in orthopedics. Thus, demand for porous PLLA and HA/PLLA is rapidly increasing, however, the relationships between their mechanical behavior and properties and their microstructure have not been well understood yet. In the present study, porous structures of PLLA and HA/PLLA with continuous pores are developed by using a solid-liquid phase separation technique and a subsequent solvent sublimation process. Size of pores and porosity are varied by changing the concentration of the solutions. Compression and shear tests are performed to evaluate the elastic moduli and strengths. Field emission scanning electron microscopy (FE-SEM) of the deformation behavior at the critical transformation points from linear elastic to nonlinear deformation is conducted to characterize the mechanism of such microscopic deformation at the critical point. Microscopic deformation and failure behavior of such porous structures are then characterized on the basis of FE-SEM results, and then correlated with the macroscopic mechanical properties. Structural modification is also tried to improve the mechanical properties to extend the applicability of the porous biomaterials." @default.
