摘　　要：以双醛淀粉(DAS)和胶原为原料,按照一定的比例将两者混合、干燥,制得双醛淀粉/胶原共混膜。本文考察了DAS对胶原膜性能的影响,研究了不同盐溶液对共混膜溶胀度的影响以及共混膜的盐敏性、pH敏感性、亲水性等。利用傅里叶红外光谱法(FTIR)和差示扫描量热法(DSC)对共混膜的化学结构进行研究,结果表明胶原与DAS之间发生了化学交联。交联作用提高了材料的稳定性,扩大了材料的应用范围。In this contribution we have developed new films by blending dialdehyde starch(DAS) and collagen with different ratios.This study was conducted to determine the effect of DAS on swelling properties of collagen films.The swelling ratio in various salt solutions,pH sensitivity and hydrophilicity of the DAS-collagen films were investigated.The chemical structure of the films was characterized by means of Fourier Transform Infrared(FTIR) Spectroscopy and Differential Scanning Calorimetry(DSC) methods.The result...
