“…To produce bulky and fluffy material using the common electrospinning method is a tricky matter. This task could be achieved either using special collectors [3] or by the usage of porogen particles, that is, chemical blowing agents, imbedded in between the nanofibers [4]. Wet electrospinning is a relatively simple and effective method to produce three dimensional (sponge-like) materials without sophisticated devices and without special chemical additives.…”

Abstract. Wet electrospinning is a useful method for 3-dimensional structure control of nanofibrous materials. This innovative technology uses a liquid collector instead of the metal one commonly used for standard electrospinning. The article compares the internal structural features of polycaprolactone (PCL) nanofibrous materials prepared by both technologies. We analyze the influence of different water/ethanol compositions used as a liquid collector on the morphology of the resultant polycaprolactone nanofibrous materials. Scanning electron micro-photographs have revealed a bimodal structure in the wet electrospun materials composed of micro and nanofibers uniformly distributed across the sample bulk. We have shown that the full-faced, twofold fiber distribution is due to the solvent composition and is induced and enhanced by increasing the ethanol weight ratio. Moreover, the comparison of fibrous layers morphology obtained by wet and dry spinning have revealed that beads that frequently appeared in dry spun materials are created by Plateau-Rayleigh instability of the fraction of thicker fibers. Theoretical conditions for spontaneous and complete immersion of cylindrical fibers into a liquid collector are also derived here.

“…oped in the textile industry [5][6][7][8], but in the recent years, applications have been published also in various biomedical fields such as wound dressing [9], wound healing [10], sterile filtration [11], tissue engineering [12,13] and drug delivery [14][15][16][17][18][19]. In former studies bioactive ingredients such as proteins and DNA have been embedded successfully in nanofibers mainly for tissue engineering purposes, while living prokaryotic cells were encapsulated by this technique mainly for industrial application in bioreactors utilizing their metabolic activity [20][21][22].…”

“…TPUs present a class of polymers that possess a range of very desirable properties: they are elastomeric, resistant to microorganisms and abrasion, and have excellent hydrolytic stability and many commercially available TPUs can be used to make good electrospinning solutions [64]. Earlier studies on the electrospinning process have been more focused on the basic principles [2][3][4] and processing parameters like the voltage applied, tip-to collector Aspects of Polyurethanesdistance, and viscosity of solution [20,[26][27][28]48]. The future use of electrospun PU materials in practical applications will require good mechanical properties.…”

“…The original ideas of using electrical potentials on the surfaces of droplets, amount of charge required for the deformation of droplets, and also apparatus for spraying of liquids by use of electrical charges can be traced back more than 100 years [1][2][3]. However, Formhals was recognized as the father of the electrospinning and he was the first to describe the operation of electrospinning in 1934 for producing polymer filaments by electrostatic repulsions between surface charges [4].…”

The electrospinning process is highlighted with the ability of fabricating fibers with diameters on the nanometer scale, small inter-fibrous pore size and high porosity, vast possibilities for functionalization with high surface area to volume or mass ratio, ease of use and instrument setup, and adaptability. It attracted a great deal of attention due to its unique properties. More than 100 different polymers have been successfully electrospun into ultrafine fibers using this technique including synthetic polymers such as polyurethane (PU). Electrospun PU nanofiber mats exhibiting good mechanical properties may have a wide variety of potential applications in high-performance air filters, protective textiles, wound dressing materials, sensors, drug delivery, etc. This chapter deals with the electrospinning of polyurethane nanofibers and their potential applications.
