“…Other studies have observed an increase in mechanical strength of the electrospun PVDF nanofibres upon addition of SiO 2 NPs . This observation was the result of the formation of uniform nonelectrosprayed nanofibres with decreased diameters . Additionally, the nanofibre diameter generally decreased on addition of high charge‐carrying fillers at optimum concentrations .…”

BACKGOUND Membrane distillation (MD) is a promising low‐cost and efficient desalination process, yet it has not been fully implemented at an industrial scale. Membrane wetting and low porosity are limiting factors leading to low water recovery rates. The current study involved the synthesis of membranes that combined high mechanical stability, porosity and superhydrophobicity, to prevent wetting, with high salt rejection and water flux. RESULTS Silica nanoparticles (SiO2NPs) were synthesized by a novel green chemistry procedure, modified with three different silane reagents [octadecyltrimethoxysilane, N‐octadecyltrichlorosilane (ODTS) and chlorodimethyl‐octadecyl silane] and finally embedded on polyvinylidene fluoride (PVDF) nanofibre membranes using an in‐situ electrospinning technique. These modified membranes displayed a Young's modulus of ∼43 MPa and showed highly porous properties (∼80% porosity, 1.24–1.41 μm pore sizes) and superhydrophobic surfaces (contact angle >150o); thus possessing parameters falling within the range of highly recommended values in MD. Remarkably, the concentration of modified SiO2NPs used to produce the superhydrophobic PVDF nanofibre membranes was significantly lower (1% w/w) than those reported in the literature (3–4% w/w), clearly indicating the efficiency of these silane reagents. CONCLUSION Membranes embedded with ODTS‐modified SiO2NPs were the most efficient; rejecting salts at high efficiencies (>99.9%) with water fluxes of ≈34.2 LMH at 60 °C, thus indicating their capacity as an energy‐efficient process to produce high purity water. © 2019 Society of Chemical Industry

“…Due to the addition of hydrophobic and hydrophilic nanoparticles of SiO 2 , which are suspended within the matrix, the characteristic band of the vibration of the Si–O–Si group between 450 cm −1 and 400 cm −1 was found. 15 –17 The results obtained from the interpretation of the spectra indicate that the nanoparticles of silica were incorporated in the PMMA matrix surface. 18…”

The characterization and wear sliding performance of the poly(methyl methacrylate) (PMMA) reinforced with hydrophilic and hydrophobic nanoparticles of silicon dioxide (SiO2) was studied. The final polymer matrix was treated in a water bath at a temperature of 100°C for 6 h. Steel balls were used to slide against the surface of PMMA specimens reinforced with SiO2 nanoparticles. Sliding wear tests were carried out in wet sliding conditions applying a drop of distilled water between the specimen and the ball. The tests were carried out up to 9000 cycles at room temperature. A frequency of 5 Hz, a stroke amplitude of 3 mm, and a maximum contact pressure of 1.087 GPa were selected. Fourier transform infrared spectroscopy spectrum, scanning electron microscopy, and microhardness and roughness of the pure PMMA and PMMA/SiO2 were obtained. The coefficient of friction and wear rates were calculated, and the main wear mechanisms found were adhesion wear, plastic deformation, ploughing, and pitting. The results showed that the addition of hydrophobic nanoparticles of SiO2 may be employed to enhance the wear resistance of external automotive parts made of polymeric compound matrix. Finally, the specimens showed a hydrophilic behavior (angular contact < 90°) due to the high polarity of the PMMA matrix and the incorporation of the SiO2 nanoparticles.

“…Also, a high flow rate affects ambient condition of the electrospinning environment which could have an adverse effect on fiber morphology [49]. In a study, M. Nasir et al [30] reported smooth nanofibers prepared by electrospinning 17 wt % CA in DMF/acetone at 0.004 mL/h. Although the concentration of CA in the precursor solution was low, smooth fibers could be attributed to a low flow rate which provided sufficient time for all solvents to evaporate before the jet reaches the collector plate.…”

State of the Art and New Directions on Electrospun Lignin/Cellulose Nanofibers for Supercapacitor Application: A Systematic Literature Review

Supercapacitors are energy storage devices with high power density, rapid charge/discharge rate, and excellent cycle stability. Carbon-based supercapacitors are increasingly attracting attention because of their large surface area and high porosity. Carbon-based materials research has been recently centered on biomass-based materials due to the rising need to maintain a sustainable environment. Cellulose and lignin constitute the major components of lignocellulose biomass. Since they are renewable, sustainable, and readily accessible, lignin and cellulose-based supercapacitors are economically viable and environmentally friendly. This review aims to systematically analyze published research findings on electrospun lignin, cellulose, and lignin/cellulose nanofibers for use as supercapacitor electrode materials. A rigorous scientific approach was employed to screen the eligibility of relevant articles to be included in this study. The research questions and the inclusion criteria were clearly defined. The included articles were used to draw up the research framework and develop coherent taxonomy of literature. Taxonomy of research literature generated from the included articles was classified into review papers, electrospun lignin, cellulose, and lignin/cellulose nanofibers for use as supercapacitor electrode materials. Furthermore, challenges, recommendations, and research directions for future studies were equally discussed extensively. Before this study, no review on electrospun lignin/cellulose nanofiber-based supercapacitors has been reported. Thus, this systematic review will provide a reference for other researchers interested in developing biomass-based supercapacitors as an alternative to conventional supercapacitors based on petroleum products.
