Abstract

In the present work, the Bombyx mori silk fibroin films have been prepared by solution casting method and irradiated with high energy electrons. The electron irradiation induced modifications in the samples were examined for structural, optical and thermal properties using X-ray diffraction (XRD), UV-Visible spectroscopy (UV-Vis) and thermogravimetric (TGA) analysis. The XRD study revealed that the structural parameters like crystallite size, crystallinity decreases with increasing radiation dose. UV-Vis study indicates the red shift after irradiation. The thermal stability of the samples decreased with irradiation.In the present work, the Bombyx mori silk fibroin films have been prepared by solution casting method and irradiated with high energy electrons. The electron irradiation induced modifications in the samples were examined for structural, optical and thermal properties using X-ray diffraction (XRD), UV-Visible spectroscopy (UV-Vis) and thermogravimetric (TGA) analysis. The XRD study revealed that the structural parameters like crystallite size, crystallinity decreases with increasing radiation dose. UV-Vis study indicates the red shift after irradiation. The thermal stability of the samples decreased with irradiation.

辐射对丝素膜的影响

本文采用溶液浇铸法制备了家蚕丝素膜，并用高能电子进行辐照。利用x射线衍射(XRD)、紫外可见光谱(UV-Vis)和热重分析(TGA)对电子辐照引起的改性样品的结构、光学和热性能进行了检测。XRD研究表明，随着辐射剂量的增加，晶体尺寸、结晶度等结构参数逐渐减小。紫外-可见研究表明辐照后红移。样品的热稳定性随辐照而降低。本文采用溶液浇铸法制备了家蚕丝素膜，并用高能电子进行辐照。利用x射线衍射(XRD)、紫外可见光谱(UV-Vis)和热重分析(TGA)对电子辐照引起的改性样品的结构、光学和热性能进行了检测。XRD研究表明，随着辐射剂量的增加，晶体尺寸、结晶度等结构参数逐渐减小。紫外-可见研究表明辐照后红移。样品的热稳定性随辐照而降低。
