“…In this range of HTT it was not observed a stretched of the fibers diameter, but an increase of tensile strength [17,18]. The average values of CF diameters obtained from SEM images are shown in Table 1 obtained from XRD and Raman spectra, respectively [4,19].…”

“…The rigidity of the pitch monomer allows pitch-based fibers to be heated to higher temperatures than PAN-based, resulting in greater graphitization. In general, this causes pitch-based fibers to be more conductive than PAN-based fibers and to contain a greater percentage of carbon [11,12]. Because carbon fibers are used in many products, a wide array of fibers with different conductivities and precursors are commercially available.…”

In this study, fast-scan cyclic voltammetry (FSCV) was used to compare responses to neurochemicals of various carbon fibers, with different conductivities and carbon precursors. Pitch-based P-25 and P-55 fibers were compared to polyacrylonitrile-based T-650 and HM fibers. Highly conductive fibers such as P-55s or HMs have larger background charging currents than lower conductivity fibers. Using a standard waveform, PAN-based fibers and less conductive fibers experience faster kinetics. With a more positive switching potential, higher conductivity fibers show faster kinetics for catecholamines and larger oxidation peak currents for anions such as ascorbic acid and 3,4-dihydroxyphenylacetic acid (DOPAC). Conductivity was found to have the greatest impact on fiber performance, but the nature of its effect depends on the waveform used and the analyte detected.

“…It is well known that the properties of CFoam can be inuenced by its processing temperature because the structure of carbon materials is modied with increasing temperature during heat treatment process. 32 As a consequence, there is an increase in the electrical conductivity of carbon materials with increasing processing temperature. In this investigation, the CFoams used are heat-treated to a temperature of 1000 C, which have considerably a high value of electrical conductivity.…”

Nanoparticles-decorated coal tar pitch-based carbon foam with enhanced electromagnetic radiation absorption capability

In the present study, to replace existing high-density radar-absorbing materials (RAM) for civil and military aerospace applications, lightweight coal tar pitch-based carbon foam (CFoam) was developed by a sacrificial template technique. The CFoam was decorated with Fe 3 O 4 and ZnO nanoparticles to improve electromagnetic (EM) radiation absorption to make it useful as RAM. To ascertain the effect of the decorated nanoparticles on the CFoam, it was characterized by scanning electron microscopy, X-ray diffraction, a vector network analyzer and a vibration sample magnetometer. It was observed that
