“…Generally speaking, the first step in the production process of CFs is to convert the powder or granular precursor into continuous fibers, that is, the spinning process (Lee et al, 2016 ). The frequently used spinning techniques can be classified as blow-spinning, electrostatic spinning, and centrifugal spinning depending on the force applied to the precursor solution/melt.…”

This review aims at offering an up-to-date comprehensive summary of carbon fibers (CFs)-based composites, with the emphasis on smart assembly and purpose-driven specific functionalization for their critical applications associated with flexible sensors. We first give a brief introduction to CFs as a versatile building block for preparation of mutil-fountional materials and the current status of research studies on CFs. This is followed by addressing some crucial methods of preparation of CFs. We then summarize multiple possibilities of functionalising CFs, an evaluation of some key applications of CFs in the areas of flexible biosensors was also carried out.

Carbon nanotubes (CNTs), a dependable allotrope of carbon, are foreseen to lead technology further to its reach. Also, the most researched carbon allotrope in its form. Drawable CNTs have recently unraveled numerous possible applications utilizing vertically aligned CNTs also termed as "CNT forest." In recent years, the rapid growth of dense and long carbon nanotube arrays has succeeded in surpassing its challenges by synthesizing dense and long CNT arrays. Length, density, and drawability tuning in the synthesis of CNT arrays have always been a complex issue lately. However, numerous research techniques emerged focusing on length and density control. Hence, this book chapter aids in unveiling the current achievements in the growth of dense and long CNT arrays and their application in spinning threads or CNT yarns with numerous other possible applications.

Synthesis of continuous spinnable carbon nanotube (CNT) fibers is the most promisingm ethod for producing CNT fibers for commercial applications. The floating-catalyst chemical vapor deposition (FC-CVD) methodi sarapid process that achieves catalystf ormation,C NT nucleation and growth, and aerogel-like sock formation within af ew seconds. However,t he formation mechanism is unknown. Herein, the progress of CNT fiber formation with bimetallic catalysts was studied, and the effect of catalystc omposition to CNT fiber synthesis and their structuralp roperties was investigated. In the case of bimetallic catalysts, the carbon source rapidly decomposesa nd generates various secondary hydrocarbon species, such as CH 4 ,C 2 H 4 ,C 2 H 2 ,C 3 H 6 ,a nd C 4 H 10 whereas monometallic catalysts generate only CH 4 and C 2 H 4 on decomposition. CNT fiber formation withF e 1 Ni 0 beginsa bout 400 mm from the reactor entrance, whereas CNT formation withF e 0.8 Ni 0.2 and Fe 0.5 Ni 0.5 begins at about 500 and 300 mm, respectively.T he formed CNT bundles and individual CNTsa re oriented along the gasf low at thesel ocations.T he enhanced rateo ff iber formation and lowering of growth temperature associated with bimetallic catalysts is explained by the synergistic effectsb etween the two metals. The synthesized CNTsb ecome predominantly semiconducting with increasing Ni contents.
