FABRICATION AND STRUCTURE CHARACTERIZATION OF INTERCOLLECTED POROUS PDLLA/HA COMPOSITE SCAFFOLDS

摘要

@@Biodegradable polymer composite materials have been of great interest in the field of medical science such as drug carriers, synthetic prosthesis and medical devices, etc. The regeneration of specific tissues aided by synthetic materials mostly depends on the porosity, pore size, pore shape, pore distribution, architecture, as well as to the mechanical properties of the scaffolds. Various methods, such as thermally induced phase separation and microsphere sintering, have been used for the
