“…8d. Unlike nanobre based lter media reported in previous studies, 7,39 the N6-PAN 2/2 and N6-15 membranes both showed outstanding ltration stability, with nearly no performance degradation under a high air ow rate (90 L min À1 ), suggesting that the local and weighted Steiner minimal tree structure and high coverage density of 2D nanonets in brous membranes would result in high ltration efficiency (99.98%) even when doped with PAN nanobres.…”

“…The electrospinning nanofibers that are characterized by small size, large specific surface area, high porosity and good connectivity are considered as the most promising materials for air filtration media [72,73]. However, electrospinning nanofibers used as air filter material have higher packing density, hindering the flow of air [74,75]. Porous bead-on-string fibers that have high specific surface area and porosity, and beads covered with micropores not only can improve packing density but also benefit air flow and adsorption for the solid particles in the air [76].…”

Bead-on-string fibers, which were initially thought to be a "by-product" of the electrospun fibers, are widely observed in electrospinning, which is a convenient method to produce nanofibers. The electrospun bead-on-string fibers were thought to have detrimental properties and were generally discarded, but recently they have gained attention since they are considered to have promising applications in many fields, including tissue engineering, drug delivery, and air/water filtration, among others. This chapter is a comprehensive and systematic literature review that summarizes the processes, methods, vital influencing factors, formation conditions, morphology changes, and applications of the electrospun bead-on-string fibers. It helps to understand the current research status and to further understand the mechanism by which these bead-on-string fibers are formed.

“…However, these nanofibers tend to pack compactly, generating fibrous membranes with a high packing density; thus, these materials are not conducive to air flow penetration. Previous studies have shown that the morphological properties of fibers, including the fiber diameter and the surface structure, and the packing density (volume fraction) of fibrous membranes have a dramatic effect on fibers' filtration performance [3,13,14]. The morphology of a polymer nanofiber can be controlled by varying the polymer solution concentration, solvent system, applied voltage, the addition of nanoparticles in the polymer solution, etc.…”
