“…As a result, the droplets are stretched extensively and form a very thin nanoscale fiber when they reach the substrate [87,88]. In the electrospinning process, a polymer solution or melt is generally deposited through a needle [89,90] or in needleless technique by coating a wire, cylinders, other objects that are used as electrodes or free surfaces with the polymer melt or solution [91][92][93]. The basic setup of electrospinning involves the application of a strong electric field to a droplet of the polymeric solution used (e.g., precursor melting solution).…”

Electrospun Carbon Nanofibers from Biomass and Biomass Blends—Current Trends

In recent years, ecological issues have led to the search for new green materials from biomass as precursors for producing carbon materials (CNFs). Such green materials are more attractive than traditional petroleum-based materials, which are environmentally harmful and non-biodegradable. Biomass could be ideal precursors for nanofibers since they stem from renewable sources and are low-cost. Recently, many authors have focused intensively on nanofibers’ production from biomass using microwave-assisted pyrolysis, hydrothermal treatment, ultrasonication method, but only a few on electrospinning methods. Moreover, still few studies deal with the production of electrospun carbon nanofibers from biomass. This review focuses on the new developments and trends of electrospun carbon nanofibers from biomass and aims to fill this research gap. The review is focusing on recollecting the most recent investigations about the preparation of carbon nanofiber from biomass and biopolymers as precursors using electrospinning as the manufacturing method, and the most important applications, such as energy storage that include fuel cells, electrochemical batteries and supercapacitors, as well as wastewater treatment, CO2 capture, and medicine.

The practice of using a massive amount of environmental unfriendly and toxic petroleum-based materials in tissue engineering and biomedical fields demands the materials, which are biodegradable, renewable, environmentally friendly, biocompatible, and bioactive. So, renewable polymers have got considerable attention due to their numerous desirable properties. The nanofibers that are prepared from renewable materials and their blends can integrate the properties of both nanofibers and renewable polymers. Development of scaffolds that mimic the construction of tissues at nanoscale is a great challenge for tissue engineering. Electrospinning is the most promising technique for nanofibers formation. Nanofibers provide a platform for cell adhesion, proliferation, and differentiation. Therefore, nanofibers from sustainable materials have been used in tissue engineering and biomedical fields. In this review, methods for nanofibers fabrication, sustainable nanofibers made from natural and synthetic polymers and their applications in tissue engineering and biomedical field, have been emphasized.

“…Electrospinning can be used to prepare nanofibrous mats with fi bre diameters between some ten and several hundred nanometres up to few micrometres [1,2]. Diff erent technologies exist, from needle-based processes using a syringe to press a polymer through the needle into an electric fi eld to coated high-voltage electrodes in the shape of wires or rotating cylinders to free surface electrospinning [3][4][5]. Diverse polymers can be electrospun, e.g.…”

Electrospun polyacrylonitrile (PAN) nanofi brous mats belong to typical precursor materials of carbon nanofibres. They have, however, the problem that they need to be fi xed or even stretched during stabilisation and ideally also during carbonisation in order to avoid undesired conglutinations and deformations of the original nanofi bre morphology, resulting in brittle behaviour of the macroscopic nanofi brous mat, which impedes several applications. In an earlier investigation, blending PAN with ZnO was shown to increase fi bre diameters and lead to unproblematic stabilisation and carbonisation of nanofi brous mats. ZnO, on the other hand, may have a negative impact on biotechnological applications such as tissue engineering. Here, we thus report on the morphological and chemical modifi cations due to blending PAN electrospinning solutions with diff erent amounts of casein. By optimising the PAN : casein ratio, relatively thick, straight nanofibres are obtained, which can be stabilised and carbonised unambiguously, without the well-known negative impact on cell adhesion due to the addition of ZnO.Elektropredene nanovlaknate koprene iz poliakrilonitrila (PAN) predstavljajo tipične prekurzorje za izdelavo ogljikovih nanovlaken. Med stabilizacijo in po možnosti tudi med karbonizacijo morajo biti pritrjene, da bi lahko preprečili neželeno zlepljenje in deformacijo prvotne nanovlaknate oblike, ki vodi v krhkost makroskopske nanovlaknate koprene in zmanjša možnosti njene uporabe. V predhodni raziskavi je bilo ugotovljeno, da mešanje PAN z ZnO vpliva na povečanje premera vlaken in omogoči stabilizacijo ter karbonizacijo nanovlaknatih kopren. ZnO pa lahko po drugi strani negativno vpliva na biotehnološke aplikacije, kot je tkivni inženiring. V članku so zato predstavljene morfološke in kemijske modifi kacije, ki so bile dosežene z uporabo predilnih raztopin za elektropredenje PAN z dodatkom različnih količin kazeina. Z optimizacijo razmerja PAN : kazein dobimo relativno debela, ravna nanovlakna, ki jih je moč stabilizirati in karbonizirati, brez da bi zaradi dodatka ZnO prišlo do dobro znanega negativnega vpliva na celično adhezijo.
