“…[198], Copyright 2016, John Wiley and Sons good biocompatibility, simple manufacturing process, and low cost of CFs are desirable properties for manufacturing implantable devices and developing practical applications. CF-based biosensors are widely used to monitor human physiological indices and cellular active components [205]. Charles et al [206] proposed that to avoid tissue damage after inserting traditional enzyme biosensors with a platinum electrode into the brain, the large platinum electrode could be replaced with platinum-plated CF microelectrodes.…”

Carbon fibers (CFs) demonstrate a range of excellent properties including (but not limited to) microscale diameter, high hardness, high strength, light weight, high chemical resistance, and high temperature resistance. Therefore, it is necessary to summarize the application market of CFs. CFs with good physical and chemical properties stand out among many materials. It is believed that highly fibrotic CFs will play a crucial role. This review first introduces the precursors of CFs, such as polyacrylonitrile, bitumen, and lignin. Then this review introduces CFs used in BESs, such as electrode materials and modification strategies of MFC, MEC, MDC, and other cells in a large space. Then, CFs in biosensors including enzyme sensor, DNA sensor, immune sensor and implantable sensor are summarized. Finally, we discuss briefly the challenges and research directions of CFs application in BESs, biosensors and more fields. Highlights CF is a new-generation reinforced fiber with high hardness and strength. Summary precursors from different sources of CFs and their preparation processes. Introduction of the application and modification methods of CFs in BESs and biosensor. Suggest the challenges in the application of CFs in the field of bio-electrochemistry. Propose the prospective research directions for CFs. Graphical abstract

“…Carbon fibers (CFs) contain more than 90 wt.% of carbon and exhibit many outstanding properties such as high modulus (200–900 GPa), high compressive strength (up to 3 GPa), high tensile strength (2–7 GPa) [ 1 , 2 ], flexibility and tunable electrochemical performance. Therefore, they can be used in multiple fields of applications [ 3 ], such as aerospace, automobile, the chemical industry, transportation, construction, energy storage, sewage treatment and others [ 4 ]. The first step of a CF production process is to select the precursor material that determines the properties and applications of CF produced from it [ 5 ].…”

Development of Porous-Polyacrylonitrile-Based Fibers Using Nanocellulose Additives as Precursor for Carbon Fiber Manufacturing

Cellulose is a renewable and environmentally friendly raw material that has an important economic and technical impact in several applications. Recently, nanocellulose (NC) presented a promising road to support the manufacturing of functional carbon fibers (CFs), which are considered superior materials for several applications because of their outstanding properties. However, the smooth and limited effective surface areas make CFs virtually useless in some applications, such as energy storage. Therefore, strategies to increase the porosity of CFs are highly desirable to realize their potential. Within this article, we present an approach that focuses on the designing of porous CF precursors using polyacrilonitrile (PAN) and NC additives using a wet spinning method. To enhance the porosity, two jet stretching (50% and 100%) and four NC additive amounts (0 wt.%, 0.1 wt.%, 0.4 wt.% and 0.8 wt.%) have been applied and investigated. In comparison with the reference PAN fibers (without NC additives and stretching), the results showed an increase in specific surface area from 10.45 m2/g to 138.53 m2/g and in total pore volume from 0.03 cm3/g to 0.49 cm3/g. On the other hand, mechanical properties have been affected negatively by NC additives and the stretching process. Stabilization and carbonization processes could be applied in a future study to support the production of multifunctional porous CF.

“…Moreover, it has been commonly used as a gas and humidity sensors for: LPG gas [11], ammonia [12], SO 2 [13], ethanol [14,15], acetone [16,17], humidity [18] and other applications, such as photocatalysts [19,20], solar cells [21,22], etc. Due to their various physical and chemical properties, carbon compounds in their different morphological forms such as fibre [23], nanotube (CNT) [24], and graphene [25], have been widely studied for their potential application in sensors as materials for reinforcing and improving the detection properties of sensitive layers based on semiconductor oxides [26][27][28]. For instance, Kaur et al [29] reported that the addition of reduced graphene oxide (rGO) to Gd-doped WO 3 led to a significant increase in acetone response with a reduction in the optimum operating temperature and improved selectivity.…”

In the present work, pure BiFeO3 (BFO) particles were synthesized by sol-gel method and mixed with carbon fibre to form composites (x%CFs-BFO, where x corresponds to 0, 4, 8 and 10 wt.%) by hydrothermal treatment at 150?C. The resulting composite powders were characterized by X-ray diffraction, Raman spectroscopy, nitrogen adsorption/desorption isotherm and scanning electron microscopy (SEM-EDX). The synthesized powders were used for gas sensors preparation by manual deposition of their mixture with polyvinyl alcohol on alumina tubes ending with two silver electrodes. The impedance of the sensitive layers was determined by impedance spectroscopy in the temperature range 100-250?C at different gaseous concentrations. The detection properties of the fabricated sensors for various volatile organic compounds were investigated. The sensors showed better sensitivity to acetone compared to other gases. The addition of carbon fibres improved the sensitivity to acetone vapour from 64 to 135% at 100 ppm and reduced the optimum operating temperature of the sensors by 20?C and the response and recovery times from (26 s/15 s) to (18 s/10 s). This study revealed that x%CFs-BiFeO3 composites are promising candidates for gas sensors.
