“…Thus CNFs satisfy the cost threshold for the automotive industry and many other filler-reinforcement applications. While the applications of CNFs in polymer composites have been extensively reported [19][20][21][22][23][24][25], limited research has been conducted on the application of CNFs in polymeric foams [18,26].…”

Carbon nanofibers (CNFs) are used as both the nucleants and the reinforcements for polystyrene (PS) foams in both batch and continuous extrusion processes with CO 2 as the blowing agent. The inclusion of CNFs exhibits substantial impact on the morphology and properties of PS foams. The presence of CNFs results in a decrease in the cell size and an increase in the cell density. Macroscopic strength enhancement of PS foams due to the incorporation of CNFs is experimentally observed. These results are qualitatively explained via a series of nanoscaled observations. Through scanning electron microscopy (SEM), the alignment of CNFs and the polymer-sheathing phenomenon are identified. The protective CNF layers around the cell wall and the substantial polymer-fiber interactions resulted in the enhancement of foam strengths. Thermal properties (heat conductivity, infrared transmission, and thermal expansion coefficient) of the PS foams can also be influenced by CNFs. Intensive shear force exerted by the twin-screw extruder broke the fibers in lengths. The impact of the fiber length on the foam structures (cell size and cell density) is also studied.

“…NFC are high valuable materials [33] that depending on their structure and surface properties can be employed in different applications such as catalyst support [34,35], anode in Li-ion batteries [36,37] or additive in polymer composites [38,39]. NFC formation during DRM has been extensively reported [6,22,40,41], although scarce information about the NFC characteristics is available in the literature.…”

A novel approach to the decomposition of biogas consisting in the simultaneous production of syngas (H 2 and CO mixture) and bio-nanostructured filamentous carbon (BNFC) is proposed. Catalysts with different active phases such as Ni, Co or Fe on Al 2 O 3 are studied in the temperature range between 600 and 900 ºC. Their behaviour was analysed considering CH 4 and CO 2 conversions, reaction rates, catalyst stability and carbon production. Additionally, the BNFC produced were characterised by transmission electron microscopy. Depending on the active phase and the reaction temperature, different carbon types were identified: fishbone, parallel and chain-like BNFC and encapsulating carbon. Large amounts of BNFC and good catalyst stability were achieved with the Ni/Al 2 O 3 catalyst at 600 ºC, pointing out that carbon accumulation is not directly responsible of catalyst deactivation and that the key factor is the nature of carbon formed during the reaction.

The main wear mechanism in the nanocomposite was abrasion of the ceramic and carbon components which act in the interface as a sort of lubricating media. The experimental results demonstrate that the addition of CNFs to the ceramic composites significantly reduces friction coefficient and wear rate, resulting in suitable materials for unlubricated tribological applications.
