Nanofibres properties

The versatile performance of nanofibre materials is the result of the choice, control and optimisation of nanofibre properties in the course of production, and they characterise the various means of fabrication, as discussed in the following. 

It is well known that catalyst support plays an important role in the performance of the catalyst and the catalyst layer. The use of high surface area carbon materials, such as activated carbon, carbon nanofibres, and carbon nanotubes, as new electrode materials has received significant attention from fuel cell researchers. In particular, single-walled carbon nanotubes (SWCNTs) have unique electrical and electronic properties, wide electrochemical stability windows, and high surface areas. Using SWCNTs as support materials is expected to improve catalyst layer conductivity and charge transfer at the electrode surface for fuel cell oxidation and reduction reactions. Furthermore, these carbon nanotubes (CNTs) could also enhance electrocatalytic properties and reduce the necessary amount of precious metal catalysts, such as platinum. 

The multiscale system also appears to be capable of providing more enhanced biological functionality, particularly for vascularization, which is favored by the interaction of ECs with the nanofibrous network.s that allow suitable cell architecture and orientation for microtubule formation. Thus, the synergistic effect of micro- and nanoscales could successfully regenerate natural tissues in vivo in the near future. Future work should focus on optimizing this process to better recapitulate key features of the native ECM, including its mechanical and biochemical properties, which would enhance the functionality of these 3D multiscale scaffolds in order to fabricate functional tissue engineered constructs.
