摘要
对纳米蛛网纤维的形态特征及形成机理进行了探讨。纳米蛛网纤维是以普通静电纺纤维薄膜为基材,具有二类网状纤维材料,其结构类似于蜘蛛网。网状纤维材料的直径平均在20nm以下,在数量上比电纺纤维要小1个等级。并且对影响形态结构的因素,从纺丝液溶液浓度、溶液电导率以及纺丝工艺参数如加电压、接收距离等方面进行分析,纳米蛛网纤维所特有的形态特征赋予了其许多特殊的性能,其应用领域也在逐步增加,特别是在过滤领域越来越被科研人员所重视。这种纤维膜的比表面积非常大,而且它的蛛网状结构使其孔隙结构和一般静电纺纳米纤维膜的孔隙结构是不一样的。这种高比表面积和特殊的气孔结构,使纤维膜在过滤方面表现优异。后市行情发展前景十分乐观。
In this paper,the morphological characteristics and forming mechanism of nano-spiderweb fibers were explored.Nano-spiderweb fibers are composed of two-dimensional fibrous materials that resemble spider-webs,made using regular electrostatically spun fibrous membranes as a framework.The diameter of the fibrous materials is less than 20 nm,which is one level smaller than electrospun fibers in quantity.From the spinning liquid solution concentration,solution conductivity and spinning process parameters such as applied voltage,receiving distance and other aspects,the factors affecting the morphology and structure of the nano-spiderweb fibers were analyzed.The unique morphological characteristics endow them with a lot of special properties,and their application fields are gradually increasing,especially in the field of filtration that is getting more and more attention of researchers.It has a very high specific surface area,and at the same time the spiderweb structure makes the pore structure of the fiber membrane different from that of the general electrostatically spun nanofiber membranes.This high surface area and pore structure make the fiber membrane perform good filtration performance,thus having an optimistic development prospect in the future market.
