“…The morphologies and properties of electrospun nanofibers and their aggregates (i.e., nanofibrous membranes) can be easily controlled by adjusting the properties of electrospinning solution (e.g., solute types, polymer relative molecular mass, solvent, concentration, viscosity, surface tension, and conductivity), process parameters (e.g., voltage, supplied rate, and collecting distance), and environmental parameters (e.g., temperature and humidity) [49] . Based on this, nanofibrous membranes with various properties and functions are easily prepared through electrospinning [50] , [51] , [52] .…”

“…The preparation of nanofibrous membrane containing bead or/and spherical structure filler is an effective method to increase the spacing of fibers [129] , [130] , [131] . By adjusting the solution parameters (i.e., surface tension; viscosity and conductivity), different forms of fibers can be prepared controllably, which can be controlled by the type and concentration of polymers [51] . The formation of bead/ball fiber in electrospinning process is closely related to the solution parameters and formed by the capillary breakup of jet [132] .…”

“…The typical electrospinning remarkably limits the fabrication of fibres with improving two or more performance simultaneously. Fortunately, the development of advanced nanotechnology brings diversified electrospinning nanotechnologies, such as coaxial and triaxial electrospinning, to break this limitation, which leads to fabricating core–shell fibres [ 22 ]. Core–shell fibres provide a strategy that the two different polymers can form the unique layer, which can improve the performance simultaneously.…”

Background The diversified combination of nanostructure and material has received considerable attention from researchers to exploit advanced functional materials. In drug delivery systems, the hydrophilicity and sustained–release drug properties are in opposition. Thus, difficulties remain in the simultaneous improve sustained–release drug properties and increase the hydrophilicity of materials. Methods In this work, we proposed a modified triaxial electrospinning strategy to fabricate functional core–shell fibres, which could elaborate design of shell component for manipulating the sustained-release drug. Cellulose acetate (CA) was designed as the main polymeric matrix, whereas polyethylene glycol (PEG) was added as a hydrophilic material in the middle layer. Cur, as a model drug, was stored in the inner layer. Results Scanning electron microscopy (SEM) results and transmission electron microscopy (TEM) demonstrated that the cylindrical F2–F4 fibres had a clear core–shell structure. The model drug Cur in fibres was verified in an amorphous form during the X-ray diffraction (XRD) patterns, and Fourier transformed infrared spectroscopy (FTIR) results indicated good compatibility with the CA matrix. The water contact angle test showed that functional F2–F4 fibres had a high hydrophilic property in 120 s and the control sample F1 needed over 0.5 h to obtain hydrophilic property. In the initial stage of moisture intrusion into fibres, the quickly dissolved PEG component guided the water molecules and rapidly eroded the internal structure of functional fibres. The good hydrophilicity of F2–F4 fibres brought relatively excellent swelling rate around 4600%. Blank outer layer of functional F2 fibres with 1% PEG created an exciting opportunity for providing a 96 h sustained-release drug profile, while F3 and F4 fibres with over 3% PEG provided a 12 h modified drug release profile to eliminate tailing–off effect. Conclusion Here, the functional F2–F4 fibres had been successfully produced by using the advanced modified triaxial electrospinning nanotechnology with different polymer matrices. The simple strategy in this work has remarkable potential to manipulate hydrophilicity and sustained release of drug carriers, meantime it can also enrich the preparation approaches of functional nanomaterials.

“…), or a blend of both [11,24], have been applied in electrospinning to prepare nanofibers, as they are soluble or do not degrade at their melting points [1,15]. Nevertheless, compared to synthetic polymers, natural polymers present advantages such as being biodegradable, safe, non-toxic, excellent biocompatibility, economical, and easily available [10,[25][26][27][28].…”

Herein, xylan-g-PMMA was synthesized by grafting poly(methyl methacrylate) (PMMA) onto xylan and characterized by FT-IR and HSQC NMR spectroscopies, and the xylan-g-PMMA/TiO2 solution was used to electrospun nanofibers at the voltage of 15 Kv, which was the first time employing xylan to electrospun nanofibers. Moreover, the electrospinning operating parameters were optimized by assessing the electrospinning process and the morphology of electrospun fibers, as follows: the mixed solvent of DMF and chloroform in a volume ratio of 5:1, an anhydroxylose unit (AXU)/MMA molar ratio lower than 1:2, the flow speed of 0.00565–0.02260 mL/min, and a receiving distance of 10–15 cm. Diameters of the electrospun fibers increased with increasing DMF content in the used solvent mixture, MMA dosage, and receiving distance. TiO2 nanoparticles were successfully dispersed in electrospun xylan-g-PMMA nanofibers and characterized by scanning electron microscopy, energy dispersive X-ray diffraction spectrum, and X-ray photoelectron spectroscopy, and their application for methylene blue (MB) degradation presented above 80% photocatalytic efficiency, showing the good potential in water treatment.
