Silk Cocoon Processing for Fiber Mats

Description

Silk cocoons can be processed into a soluble material that is useful for making biomaterials. Silk fibers have been used for fabrics and threads for centuries, but turning them into a versatile pre-polymer solution is a newer technique. That solution can then be shaped into materials with controllable mechanical properties.<...

生物衍生材料具有合成材料无法企及的关键特性,能够制造具有改进性能的复杂结构。生物材料是由活的或曾经活的生物体创造或生产的材料。这些材料,例如丝绸,通常会经过各种加工步骤才能达到可用和可控的状态。然后,加工后的生物材料可用于形成特定结构,例如纤维垫、水凝胶和薄膜。本影片将介绍蚕茧的加工过程,然后对加工后的材料进行静电纺丝,形成纤维毡。

蚕丝是蛋白质聚合物,被各种昆虫(如蜘蛛)纺成纤维。然而,用于生物工程的蚕丝最常见的来源于蚕蛾物种 Bombyx mori(通常称为蚕)的幼虫,几十年来一直被商业用于医用缝合线。家蚕丝材料是从茧中提取的,茧由包裹在丝胶蛋白外壳中的丝素蛋白组成。丝胶蛋白是一种胶状蛋白质,可将茧固定在一起。丝素蛋白的特征是高度重复的氨基酸序列,以丙氨酸、甘氨酸和丝氨...
