“…TGA curves of PEG fibers prepared with different aluminosilicate contents are shown in Figure a. Other studies that investigated the thermal degradation of PEG have found that degradation process of PEG occurs in one step in which chain breakage leads to by‐products such as ethanol, methanol, alkenes, non‐cyclic ethers, formaldehyde, acetaldehyde, ethylene oxide, water, carbon, carbon monoxide, and carbon dioxide . Samples with nanoparticles displayed the onset of mass loss at temperatures lower than the pure PEG sample as expected since aluminosilicate nanoparticles can decrease the stability of the system as also observed by Li et al Moreover, the constant weight values above 600 °C for fibers containing nanoparticles showed that the soft template (PEG) was removed.…”

In this work, nanostructured aluminosilicate fibers are prepared by submitting poly(ethylene glycol) (PEG) electrospun fibers containing sol‐gel derived aluminosilicate nanoparticles to a calcination treatment. The prepared materials are characterized by scanning electron microscopy (SEM), dynamic light scattering (DLS), infrared spectroscopy (FTIR), x‐ray diffraction (XRD) and thermal analyses (DSC and TGA). The calcination of hybrid electrospun PEG fibers containing 20 wt% of nanoparticles generated well‐defined high‐surface area aluminosilicate fibers containing residual carbon. The production of nanostructured aluminosilicate fibers displaying high porosity and residual carbon can improve the performance of catalysts and membranes.

To overcome the limits of low adsorption capacity and the separation difficulty of solid from liquid phase for graphene oxide (GO), a novel nanocomposite graphene oxide-manganese oxide (GOMO) was facilely fabricated under ultrasonic radiation. The structures and micro-morphology of the products were characterized by fourier transform infrared (FT-IR) spectroscopy, raman shift spectroscopy, X-ray diffraction (XRD) pattern and scanning electron microscopy (SEM). The effect of solution pH, adsorbent dose, contact time, initial uranium concentration, ionic strength and temperature on uranium removal efficiency was studied by batch adsorption experiments. The product GOMO was used to examine the feasibility of the removal of high salt content in uranium-containing wastewater. The adsorption results were fitted using the Langmuir and Freundlich isotherm models. The kinetic parameters in the adsorption process were measured and fitted. Five adsorption/desorption cycles were performed using 3 M HNO3 as the regenerant in order to evaluate the reuse of GOMO.

“…It is worth mentioning that due to the high porosity and outstanding specific surface area of porous structure, it can be used in various applications such as tissue engineering [28,29], drug delivery [30], water treatment applications [31][32][33][34], sensors [35,36], photocatalysis [37,38], lithium-ion batteries [39,40], energy harvesting [6], and so on [41][42][43]. To the best of our knowledge, few studies have investigated the generation of porous fibers using a bath collector [44][45][46].…”

Porous nanofibers are of great significance to different applications. Herein, interconnected macroporous nanofibers were electrospun from polystyrene (PS)/chlorobenzene (CB)/N'Ndimethylformamide (DMF) using a bath collector. The effects of the solvent ratio and bath collector temperature on the structure of PS fibers are studied. The results showed that the presence of CB is essentials for the formation of porous fibers. Furthermore, the size of the pores on the surface of fibers increases by increasing the ratio of CB as well as decreasing the temperature of the bath collector. The formation mechanism of the interconnected macroporous structure is discovered. The BET test showed that these fibers had an outstanding specific surface area (SSA) of~44.27 m 2 g −1 . We believe our findings can be used as a good reference for the generation of electrospun nanofibers with interconnected macroporous using a water bath as a collector.
