摘要: Lecithin was, for the first time, blended with PLLA to prepare scaffold material tissue engineering applications in present study. Solution blending was used incorporate (containing 0–10 wt %) enhance blend films biocompatibility, hydrophilicity and toughness while maintaining mechanical strength of PLLA. The results FTIR-ATR analysis indicated that amino groups lecitin existed films. DSC Tg decreased increase lecithin content percentage elongation markedly increased content. proliferation viability vascular smooth muscle cell cultures on PLLA/Lecithin 3–7 were significantly enhanced compared pure culture plates. © 2007 Wiley Periodicals, Inc.
