摘要
木薯蚕丝是仅有的几种被广泛饲育生产的野蚕丝之一,极具开发利用价值,研究与认识木薯蚕丝结构与性能是进一步开拓其应用领域的重要基础,而热学性能是蚕丝开发应用中被广泛关注的方面。文章采用对比分析的方法,对木薯蚕丝、柞蚕丝和桑蚕丝的热学性能进行了表征和分析,包括微商热重法(TGA/DTG)、差示扫描量热法(DSC)和动态热机械分析法(DMA)等手段。研究结果表明:相对于柞蚕丝和桑蚕丝,木薯蚕丝的热失重区间、最速热失重温度、储能模量和损耗模量等均较大,说明木薯蚕丝具有良好的热稳定性,进而可推断木薯蚕丝在改善或调节丝蛋白复合类材料的热稳定性方面有望作为一种有效组分来使用。
Cassava silk,one of few kinds of wild silk widely cultivated,has great value of development and utilization. The research and understanding of the structure and performance of cassava silk is very important for its development and application. The thermal property receives extensive attention in silk development and application.In this paper,the thermal properties of cassava silk,tussah silk and mulberry silk were characterized and analyzed by means of thermal gravimetric analyzer/derivative thermogravimetry（ TGA/DTG）,differential scanning calorimetry（ DSC） and dynamic thermomechanical analysis（ DMA）. The results show that,compared with tussah silk and mulberry silk,the cassava silk shows broader thermal weight loss range,the higher thermal weight loss temperature,larger storage modulus and loss modulus,suggesting the excellent thermal stability of cassava silk. It is an effective component to improve or adjust heat stability of fibroin compound martials.
