摘要：
A series of porous silk fibroin poly(vinyl alcohol) blend gets were prepared from corresponding aqueous mixtures by freeze- or air-drying. and their structure and mechanical properties were examined. The air-dried gels had higher crystallinity and much greater strengths than the freeze-dried gels. and therefore are suitable for mechanical uses. The freeze-dried gels had characteristic porous structure potentially useful as cell culture substrate. Its structure could be systematically varied by changing freezing temperature and freeze thaw pretreatments before drying. (C) 2002 Elsevier Science B.V. All rights reserved.
