摘要: 综述了丝胶在凝胶溶液转变过程中的一系列物理性能变化,其中包括凝胶化过程中透光率、表面张力、胶粘强度的变化,说明了温度、溶液浓度、pH值对凝胶化速度的影响。介绍了用X射线衍射、圆二色吸收光谱、红外吸收光谱、DTA等测试方法对引起这些变化的微观机制,说明了丝胶凝胶是一种热可逆性凝胶。同时还介绍了丝胶与几种不同的物质共混或交联所得产物的凝胶特性及其应用。

Abstract: The studies on the changes of physical properties of sericin during the transformation between gel and solution were reviewed,including light transmission rate,surface tension and adherence strength.The influences of temperature,solution concentration and pH value on the gelation speed of sericin were also elucidated.The micro-mechanism of these changes was examined using X ray diffraction,circular dichroism spectrum,infrared spectrum and DTA.It was proved that the sericin gel is thermal reversible.The gelation characteristics and applications of sericins blended or cross-linked with other substances were also described.
