“…Natural biopolymers such as Chiton, chitosan, gum tragacanth, and guar gum blended with synthetic biocompatible polymers (PVA or PEO) have been reported to be suitable for producing electrospun membranes [145][146][147][148][149][150]. Very recently, natural tree polymers such as GA, GK, and KG have undergone electrospinning and the system and process parameters have been standardised to produce smooth and uniform nanofibres [151][152][153][154][155].…”

Abstract:The recent advances and potential applications of nanoparticles and nanofibres for energy, water, food, biotechnology, the environment, and medicine have immensely conversed. The present review describes a 'green' method for the synthesis and stabilization of nanoparticles and 'green electrospinning' both using tree gums (arabic, tragacanth, karaya and kondagogu). Furthermore, this review focuses on the impending applications of both gum stabilized nanoparticles and functionalized membranes in remediation of toxic metals, radioactive effluents, and the adsorptive removal of nanoparticulates from aqueous environments as well as from industrial effluents. Besides, the antibacterial properties of gum derivatives, gum stabilized nanoparticles, and functionalized electrospun nanofibrous membranes will also be highlighted. The functionalities of nanofibrous membranes that can be enhanced by various plasma treatments (oxygen and methane, respectively) will also be emphasized.

“…At low viscosity, the molecular entanglement becomes poor which leads to the formation of beaded nanofibers [8]. On the other hand, polymer MW manifests the entanglement and intertwinement of the polymer chains as well as the elongation of the whole polymer chain between the collecting plate and the spinneret [9]. Polymer entanglement, intertwinement, and elongation improve with an increase in polymer MW, which leads to the formation of non-beaded nanofibers.…”

Electrospun cyclodextrin (CD)-based nanofibers with capabilities to remove pollutants from water have been synthesized and characterized. The high-quality nanofibers presented here were synthesized in two simple steps that involved in-situ electrospinning of the nanofibers and all nanocomponents, followed by the reduction of silver (Ag + ) and iron (Fe 3+ ) ions to nanoparticles using an environmentally benign process that involved irradiation of the electrospun fibers using a tailor-made UV-equipped furnace at low temperatures. In the previously reported study it was observed that Ag and Fe nanoparticles effectively removed a range of different strains of Gram-negative and Gram-positive bacteria from water. As such, this study focused on improving the thermal and mechanical properties of the nanofibers prepared from polymer blends of β-CDs with cellulose acetate (CA) and small additions (2 wt%) of functionalized multiwalled carbon nanotubes (fMWCNTs). The electrospinning parameters were varied to determine the optimum conditions for preparation of uniform nonbeaded nanofibers. Bead-free and uniform nanofibers were obtained at a polymer concentration of 32% at the ratio of 1:1 β-CDs:CA, syringe injection flow rate of 0.7 mL h −1 , 15 cm between the tip of the spinneret and the collector, and a voltage of 16 kV. The addition of f-MWCNTs was found to improve the tensile strength of the nanofibers by twofold, relative to nanofibers with no f-MWCNTs. The thermal degradation of the nanofibers was improved by a magnitude of 50°C. The study has shown that adding small amounts of f-MWCNTs improved the thermal stability and mechanical strength of the CD/CA nanofibers significantly. ARTICLE HISTORY
