“…These bio-based polymer blends are used for various commercial applications in the industrial field and are specially developed for this purpose. Such precursor electrospun fibers and carbon fibers are of great interest for a range of applications, including drug delivery and regenerative medicine [22], tissue engineering [23], cells growing [24], catalysts [25], filters [26][27][28] or protective clothing [29]. Not only artificial polymers [30] and biopolymers [31,32] can be used for the production of nanofiber mats, but also polymers mixed with non-soluble materials can be used for electrospinning [33,34].…”

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.

“…Since PVDF is a chemically inert material, NPs cannot attach to the prepared nanofibers' surface. However, as previously demonstrated, 31 the polymer's functionalization by hydroxyl groups can enable the fibers' decoration by NPs. To promote such functionalization, the membrane is subjected to a dehydrofluorination process by immersing it in a 1.8 M potassium hydroxide (KOH, Fluka) solution in isopropanol (IPA, penta s.r.o.)…”

“…The membrane preparation consisted of three steps. 31 Firstly, the nanofibers were prepared through direct current electrospinning of PVDF (13 wt%, Solef 1015) dissolved in N , N -dimethylformamide (DMF, penta s.r.o.). The electrospinning process was performed using an electrospinning system (Nanospider, NS 8S1600U, Elmarco), and the produced nanofibers were collected over silicone paper.…”

“…Pristine PVDF is naturally hydrophobic. PVDF may be converted into a hydrophilic membrane by modifying its surface using alkaline treatment [ 23 , 24 ]. It was found that PVDF membranes can be attacked and degraded upon exposure, even to a low concentration of NaOH (0.01 M) solution [ 25 ].…”

Chemical Cleaning Process of Polymeric Nanofibrous Membranes

Membrane fouling is one of the most significant issues to overcome in membrane-based technologies as it causes a decrease in the membrane flux and increases operational costs. This study investigates the effect of common chemical cleaning agents on polymeric nanofibrous membranes (PNM) prepared by polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN), and polyamide 6 (PA6) nanofibers. Common alkaline and acid membrane cleaners were selected as the chemical cleaning agents. Membrane surface morphology was investigated. The PAN PNM were selected and fouled by engine oil and then cleaned by the different chemical cleaning agents at various ratios. The SEM results indicated that the use of chemical agents had some effects on the surface of the nanofibrous membranes. Moreover, alkaline cleaning of the fouled membrane using the Triton X 100 surfactant showed a two to five times higher flux recovery than without using a surfactant. Among the tested chemical agents, the highest flux recovery rate was obtained by a binary solution of 5% sodium hydroxide + Triton for alkaline cleaning, and an individual solution of 1% citric acid for acidic cleaning. The results presented here provide one of the first investigations into the chemical cleaning of nanofiber membranes.
