Tissue engineered scaffolds were prepared from blends of poly(L-lactide) (PLLA) and poly(ε- caprolac-tone) (PCL) by gelation-freeze-drying. The morphology of scaffolds with PLLA/PCL compositions of 100/0, 90/10, 80/ 20, 70/30 (wt% ) under different solvent exchange conditions was studied.
The influences of VM on B and the yield strengeh (oo.2) are clearIy related to the influence onthe circularization degree of the initial stage of tension curve. B～σ0.2 regression anaIysis of granular tissue (GS) andgranular bainite (Bg) containing MuA tissue shows that B and σ0.2 are good linear dependence reIation.
Organic-inorganic hybrid materials have been extensively studied due to their potential applications of such materials to living tissues, photochemistry, electromagnetism, catalysis, adsorption, and so on.
