综述了6种制备单根扭曲螺旋结构微纳米纤维和4种制备多根螺旋缠绕结构纤维(微纳米绳索)的静电纺丝方法,发现当前多根螺旋缠绕纤维大都以附加机械力或电场力扭曲成型,单根螺旋纤维则以改变纤维内部力学分布达到扭曲成型目的.此外,分析了研究现状和发展前景.
In this article 6 means of preparing individual helical nanofibers and 4 means of preparing helical twisted nanofiber ropes are mainly reviewed. It is found that electrospun nanoropes are usually made via additional mechanical force or auxiliary alternating electric field force,whereas single nanofibers with helical structure are induced by intra-fibrillar mechanostriction. In addition,the present research situation and development prospects are discussed.
