“…PAN is the most common auxiliary polymer thanks to its high carbon yield and mechanical properties (Ding et al 2016 ). Besides PAN (Ruiz-Rosas et al 2010 ; Choi et al 2013 ; Xu et al 2013 , 2014 ; Ding et al 2016 ; Dalton et al 2019 ; Jayawickramage et al 2019 ; Demiroğlu Mustafov et al 2019 ; Dai et al 2019 ; Zhang et al 2020b ; Du et al 2020a ), many other polymers have also been used as auxiliary polymers to enhance lignin spinnability, such as PVP (Ma et al 2018 ; Cao et al 2020 ), PVA (Ago et al 2012 ; Lai et al 2014 ; Ma et al 2016 , 2019 ; Zhao et al 2018b ; Jayawickramage and Ferraris 2019 ; Roman et al 2019 ), PEO (Dallmeyer et al 2010 ; Hu and Hsieh 2013 ; Cho et al 2019 ; Du et al 2020b ), TPU (Culebras et al 2019 ), and PLA (Culebras et al 2019 ). Worth reporting that, to some less extent instead of blending, direct synthesize of lignin and PAN copolymer has been reported as a precursor of LCNFs for energy applications (Youe et al 2016 , 2018 ).…”

Graphic abstract Polyacrylonitrile (PAN)-based carbon precursor is a well-established and researched material for electrodes in energy storage applications due to its good physical properties and excellent electrochemical performance. However, in the fight of preserving the environment and pioneering renewable energy sources, environmentally sustainable carbon precursors with superior electrochemical performance are needed. Therefore, bio-based materials are excellent candidates to replace PAN as a carbon precursor. Depending on the design requirement (e.g. carbon morphology, doping level, specific surface area, pore size and volume, and electrochemical performance), the appropriate selection of carbon precursors can be made from a variety of biomass and biowaste materials. This review provides a summary and discussion on the preparation and characterization of the emerging and recent bio-based carbon precursors that can be used as electrodes in energy storage applications. The review is outlined based on the morphology of nanostructures and the precursor’s type. Furthermore, the review discusses and summarizes the excellent electrochemical performance of these recent carbon precursors in storage energy applications. Finally, a summary and outlook are also given. All this together portrays the promising role of bio-based carbon electrodes in energy storage applications.

“…Apart from this, GNMs can be decorated on the surface of electrospun nanofibers (ESNFs) using post-processing methods enabling the possibility to fabricate multifunctional GNMs nanostructures with novel and/or improved biosensing performance. GNMs-polymer nanocomposites prepared by electrospinning possess both the advantages of polymers such as lightweight, flexibility and moldability, and special functionality of GNMs such as high strength, thermal stability and electrochemical properties [32]. Furthermore, the functionality and the dispersity of GNMs can be further improved by incorporating secondary phases such as precious metals, metal oxides, gold nanoparticles, CNTs, and hydroxyapatite either during electrospinning or in the post-processing methods, e.g.…”

Owing to the unique structural characteristics as well as outstanding physio-chemical and electrical properties, graphene enables significant enhancement with the performance of electrospun nanofibers, leading to the generation of promising applications in electrospun-mediated sensor technologies. Electrospinning is a simple, cost-effective, and versatile technique relying on electrostatic repulsion between the surface charges to continuously synthesize various scalable assemblies from a wide array of raw materials with diameters down to few nanometers. Recently, electrospun nanocomposites have emerged as promising substrates with a great potential for constructing nanoscale biosensors due to their exceptional functional characteristics such as complex pore structures, high surface area, high catalytic and electron transfer, controllable surface conformation and modification, superior electric conductivity and unique mat structure. This review comprehends graphene-based nanomaterials (GNMs) (graphene, graphene oxide (GO), reduced GO and graphene quantum dots) impregnated electrospun polymer composites for the electro-device developments, which bridges the laboratory setup to the industry. Different techniques in the base polymers (preprocessing methods) and surface modification methods (post-processing methods) to impregnate GNMs within electrospun polymer nanofibers are critically discussed. The performance and the usage as the electrochemical biosensors for the detection of wide range analytes are further elaborated. This overview catches a great interest and inspires various new opportunities across a wide range of disciplines and designs of miniaturized point-of-care devices.

Fabrication and Characterization of Electrospun Poly(acrylonitrile-co-Methyl Acrylate)/Lignin Nanofibers: Effects of Lignin Type and Total Polymer Concentration

et al. 2021

Lignin macromolecules are potential precursor materials for producing electrospun nanofibers for composite applications. However, little is known about the effect of lignin type and blend ratios with synthetic polymers. This study analyzed blends of poly(acrylonitrile-co-methyl acrylate) (PAN-MA) with two types of commercially available lignin, low sulfonate (LSL) and alkali, kraft lignin (AL), in DMF solvent. The electrospinning and polymer blend solution conditions were optimized to produce thermally stable, smooth lignin-based nanofibers with total polymer content of up to 20 wt % in solution and a 50/50 blend weight ratio. Microscopy studies revealed that AL blends possess good solubility, miscibility, and dispersibility compared to LSL blends. Despite the lignin content or type, rheological studies demonstrated that PAN-MA concentration in solution dictated the blend’s viscosity. Smooth electrospun nanofibers were fabricated using AL depending upon the total polymer content and blend ratio. AL’s addition to PAN-MA did not affect the glass transition or degradation temperatures of the nanofibers compared to neat PAN-MA. We confirmed the presence of each lignin type within PAN-MA nanofibers through infrared spectroscopy. PAN-MA/AL nanofibers possessed similar morphological and thermal properties as PAN-MA; thus, these lignin-based nanofibers can replace PAN in future applications, including production of carbon fibers and supercapacitors.
