“…As shown in Figure 5e, SL fibers could be thermostabilized by a heating rate of 5°C min -1 for a conventional oxidative treatment with air. The heating rate was comparable to the highest heating rate previously reported, which was carried out with kraft lignin (Dallmeyer et al 2014). The simple conversion of SL to an infusible form can be attributed to the low thermal mobility of the original SL, which is attributed to its highly condensed structure.…”

Electrodes has been prepared for application in an electric double layer capacitor (EDLC) based on polyethylene glycol lignin (PEGL) and soda lignin (SL) derived from cedar wood. Fibers with a diameter of 23 μm were prepared by direct melt electrospinning of PEGL. Much finer fibers of 3.6 μm diameter were obtained by dry electrospinning of 70% PEGL in a dimethyl formamide (DMF) solution at 145°C. The dry electrospinning of SL alone in an alkaline aqueous solution was not achievable, but this was possible of a mixture of SL and polyethylene glycol (M w = 500 000) at a ratio of 99/1, which resulted in thin SL fibers with a diameter of 0.85 μm. These fibers were converted into activated carbon fibers (ACFs) by thermostabilization, carbonization, and steam activation. The specific Brunauer, Emmett and Teller (BET) surface areas of the resulting PEGL-ACFs and SL-ACFs were 1880 m 2 g -1 and 1411 m 2 g -1 , respectively. PEGL-ACFs electrodes with an organic electrolyte exhibited an impedance of 1.6 Ω and a specific capacitance of 92.6 F g -1 at a scan rate of 1 A g -1 , and the SL-ACFs electrodes had an impedance and specific capacitance of 4.5 Ω and 55.6 F g -1 , respectively.

Fabrication of electro-conductive fi ber is a novel process. Nanocomposites of multiwall carbon nanotube/polyamide66 were produced by electrospinning with different amounts of multiwall carbon nanotube. Field emission scanning electron microscope and Fourier transform infrared spectroscopy of samples proved the existence of multiwall carbon nanotube distribution in polyamide 66 nanofi bers. Results showed that electro conductivity of electrospun multiwall carbon nanotube/polyamide 66 nano fi ber has increased in comparison with electrospun polyamide 66. Moreover, UV blocking of samples was investigated which has shown that using multiwall carbon nanotube in polyamide 66 increases UV blocking of fi bers. Furthermore, anti-bacterial activity of nanocomposite showed that these nanocomposites have antibacterial property against both Staphylococcus Aureus and Escherichia Coli bacteria according to AATCC test method.

Biomass-derived binderless fibrous carbon electrodes for ultrafast energy storage

The possibility to store energy efficiently and sustainably at little cost is crucial to prevent climate change and exhaustion of natural resources. In this communication we demonstrate that interconnected and porous carbon fibers easily obtained from lignin exhibit ultrafast charge-discharge and excellent energy density and cyclability performance, to be used as binderless and flexible electrodes in supercapacitors.Electrochemical capacitors, usually referred to as supercapacitors, are electrochemical devices for electrical energy storage and harvesting applications that can complement or replace batteries when high power delivery or uptake and/or long cycling stability are required. Additionally, these devices improve efficiencies in supply systems (such as internal combustion engines, renewable energy systems, batteries and fuel cells) by storing energy when in excess or not needed. Thus, they are considered as one of the most powerful technologies that will provide a more efficient and sustainable utilization of energy on a short-term and real scenario of increasing energy costs and threatening climate change. 1 In spite of such relevance, the widespread utilization of supercapacitors has not been achieved due to a high cost to performance ratio. Among different electrode candidates, the last decade has witnessed a very intense research in the capacitance and storage performance of different nanostructured carbons, like graphene, CNTs, fullerenes, CNFs, onions, templated carbons, etc. 1 Nevertheless, apart from the significant progress on fundamental aspects, the complex and expensive manufacture as well as the complicated handling and electrode processing of these carbon materials make uncertain their feasible application. Accordingly, while novel electrode materials and chemistries are being developed to improve the storage performance, further research on simpler and cheaper manufacture and processing is demanded. Activated carbons (AC) derived from biomass and polymers have been identified as the currently most viable materials for supercapacitors, from both economic and sustainability points of view. 1a To attain the specifications for widespread commercialization, various issues need to be solved, being the most important to produce AC with a high accessible surface area and a sufficiently high electrical conductivity. On the one hand, biomass and natural polymers show a heterogeneous structure and contain impurities that complicate their processing to produce adequate conductive carbon electrodes. On the other hand, the derived ACs are conventionally obtained as powder or granular materials. Both the particle-like morphology and porosity strongly increase their inter-and intra-particle electrical resistances, 1e respectively, what makes necessary their processing into electrode pastes (by using auxiliary binders and conductivity promoters). This generates many electric point contacts that decrease their mechanical and chemical stability. 2 Hence the development of binderless porous carbons by a dire...
