“…The solution is then spun and fiber stabilization is effected by soaking the fibers in a solution containing formaldehyde and hydrochloric acid at 90°C for 2 h. The authors presented much analytical data for the process, including tensile strengths and moduli that approach 1.7GPa (247 ksi; 173 kg‐f/mm 2 ) and 176 GPa (25.5 Msi; 17.9 × 10 3 kg‐f/mm 2 ), respectively. Lin et al report similar syntheses as do others . However, it is unclear if these processes could be economically or environmentally attractive.…”

The confluence of two US energy policy mandates, the 2012 Corporate Average Fuel Economy Standards and Renewable Fuels Standard #2, provide the opportunity to examine the possibility of high-value materials from lignin with increased depth. In this case, the desire to provide lighter, low-cost materials for automobiles to reduce fuel consumption, and to improve the economics of biorefineries for fuel production, have led to an increased interest in low-cost carbon fiber manufacture from lignin. For this review the authors provide the context of subject matter importance, a cost comparison of potential low-cost carbon fibers, a brief review of historical work, a review of more recent work, and a limited technical discussion followed by recommendations for future directions. As the available material for review is limited, the author includes many references to publicly available government documents and reviewed proceedings that are generally difficult to locate.

“…Decomposition temperatures (T d ) are determined as the temperature corresponding to 5% mass losses in the samples and are also listed in Table III. 46 In general, a precursor should have high thermal stability at the spinning temperatures, so that the melt-spinning is not interrupted by the formation of bubbles. 46 In general, a precursor should have high thermal stability at the spinning temperatures, so that the melt-spinning is not interrupted by the formation of bubbles.…”

The possibility of producing carbon fiber from an industrial corn stover lignin was investigated in the present study. Asreceived, high-ash containing lignin was subjected to methanol fractionation, acetylation, and thermal treatment prior to melt spinning and the changes in physiochemical and thermal properties were evaluated. Methanol fractionation removed most of the impurities in the raw lignin and also selectively removed the molecules with high melting points. However, neither methanol fractionation nor thermal treatment rendered melt-spinnable precursors. The precursors were highly viscous and decomposed easily at low temperatures, attributed to the presence of H, G phenolic units, and abundant hydroxycinnamate groups in herbaceous lignin. A two-step acetylation of methanol fractionated lignin greatly improved the mobility of lignin, while enhancing the thermal stability of the precursor during melt-spinning. Fourier Transform Infrared and 2D-NMR analysis showed that the contents of phenolic and aliphatic hydroxyls, as well as the hydroxycinnamates, decreased in the acetylated precursors. The optimum precursor was a partially acetylated lignin with a glass transition temperature of 85 8C. Upon oxidative stabilization and carbonization, the carbon fibers with an average tensile strength of 454 MPa and modulus of 62 GPa were obtained. The Raman spectroscopy showed the I D /I G ratio of the carbon fiber was 2.53. V C 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45736.

“…For example, the integrated melt spinning techniques of centrifugal melt spinning [85] and melt electrospinning [86,87] not just preserve the features of melt spinning, but also allow higher productivity and better control of the size of spun fibers. Meticulous design on the spinneret can also tune the property of the melt spun fibers [88]. In addition, the melt spun fibers can be modified by porous surface coating to obtain desired functions, for example, controlled drug delivery function [89].…”

The objective of this article is to provide an overview on the current development of micro- and nanoporous fiber processing and manufacturing technologies. Various methods for making micro- and nanoporous fibers including co-electrospinning, melt spinning, dry jet-wet quenching spinning, vapor deposition, template assisted deposition, electrochemical oxidization, and hydrothermal oxidization are presented. Comparison is made in terms of advantages and disadvantages of different routes for porous fiber processing. Characterization of the pore size, porosity, and specific area is introduced as well. Applications of porous fibers in various fields are discussed. The emphasis is put on their uses for energy storage components and devices including rechargeable batteries and supercapacitors.
