Electrospun nanofiber mats are nowadays often used for biotechnological and biomedical applications, such as wound healing or tissue engineering. While most studies concentrate on their chemical and biochemical properties, the physical properties are often measured without long explanations regarding the chosen methods. Here, we give an overview of typical measurements of topological features such as porosity, pore size, fiber diameter and orientation, hydrophobic/hydrophilic properties and water uptake, mechanical and electrical properties as well as water vapor and air permeability. Besides describing typically used methods with potential modifications, we suggest some low-cost methods as alternatives in cases where special equipment is not available.
如今，电纺纳米纤维垫常用于生物技术和生物医学应用，如伤口愈合或组织工程。虽然大多数研究集中在它们的化学和生化特性上，但物理特性的测量往往没有对所选用方法进行详细说明。在此，我们概述了拓扑特征的典型测量方法，如孔隙率、孔径、纤维直径和取向、疏水/亲水特性和吸水率、机械和电学特性以及水蒸气和空气渗透率。除了描述具有潜在改进的常用方法外，我们还建议了一些低成本方法，以便在没有特殊设备的情况下作为替代方案。
