“…A combination of nano-and sub-microfibres was obtained for the PEU solutions with the lowest (59.5 μS cm -1 ) and the highest conductivity (150.9 μS cm -1 ) while a relatively narrow distribution of nanofibre diameters was found for the PEU solution with a medium conductivity (107.9 μS cm -1 ). The non-uniformity of fibre diameters could have been caused by a broad molecular-weight distribution, whose relation to the fibre distribution was reported in the work of J. Lyons et al, 6 though for a different type of material.…”

This work deals with an investigation of fabrications of nanofibres based on biodegradable polylactic-acid/polyethylene-glycolchain-linked copolymers, using the electrospinning technique. Crucial attention is paid to describing the effect of polymer-solution conductivity on the morphology of the resulting nanofibres. Nanofibre systems were studied with scanning electron microscopy and the subsequent image analysis of nanofibre diameters. Hydrolytical degradability of the investigated copolymers was studied using gel permeation chromatography. The results show a significant effect of polymer-solution conductivity on the quality of nanofibres. Keywords: electrospinning, nanofibres, polylactide polyethylene glycol copolymer To delo obravnava preiskavo izdelave nanovlaken na osnovi biorazgradljive, v verigo povezanih kopolimerov polimle~ne kisline/polietilen glikola, z uporabo tehnike elektropredenja. Najve~ja pozornost je usmerjena v opis vpliva prevodnosti raztopine polimera na morfologijo izdelanih nanovlaken.

“…In the 1980s, Larrondo and St John Manley [13][14][15] first reported the electrospinning of a molten polymer. Lyons et al 16 reported a relationship between molecular weight and fiber size in this system. Zhou et al 17 then obtained polylactic acid nanofibers by melt electrospinning in a guided heating chamber.…”

The broad application of electrospun nanofibrous scaffolds in tissue engineering is limited by their small pore size, which has a negative influence on cell migration. This disadvantage could be significantly improved through the combination of nano- and microfibrous structure. To accomplish this, different nano/microfibrous scaffolds were produced by hybrid electrospinning, combining solution electrospinning with melt electrospinning, while varying the content of the nanofiber. The morphology of the silk fibroin (SF)/poly(ε-caprolactone) (PCL) nano/microfibrous composite scaffolds was investigated with field-emission scanning electron microscopy, while the mechanical and pore properties were assessed by measurement of tensile strength and mercury porosimetry. To assay cell proliferation, cell viability, and infiltration ability, human mesenchymal stem cells were seeded on the SF/PCL nano/microfibrous composite scaffolds. From in vivo tests, it was found that the bone-regenerating ability of SF/PCL nano/microfibrous composite scaffolds was closely associated with the nanofiber content in the composite scaffolds. In conclusion, this approach of controlling the nanofiber content in SF/PCL nano/microfibrous composite scaffolds could be useful in the design of novel scaffolds for tissue engineering.

“…This intrinsic feature offers them drastically increased surface to volume ratio and high aspect ratio. There are several methods to prepare nanofibers, encompassing top-down (melt-blown (Ellison et al, 2007), melt electrospinning (Dalton et al, 2007, Lyons et al, 2004, islands-in-the-sea (Nakata et al, 2007), and electrospinning (Bhardwaj and Kundu)), and bottom-up (interfacial polymerization (Xing et al, 2008), self-assembly (Viney, 2004), and phase separation (Zhao et al)) approaches. Nanofibers produced from electrospinning have a naturally formed porous structure with excellent pore interconnectivity and the pores are in the range between tens of nanometers to a few micrometers.…”
