“…CB is one of the most widely used conductive nanoparticles in industrial applications and is considered a suitable candidate because of its low cost, good dispersion ability, and, especially, synergistic effect with carbon nanotubes [9,10]. When CB is compounded with rubbers, the tensile strength, tear strength, modulus and abrasion resistance are improved [10,11].…”

Filler effects on H2 diffusion in nitrile butadiene rubbers (NBRs) blended with carbon black and silica fillers of different concentrations are first investigated by employing a volumetric analysis. Total uptake, solubility, and diffusivity of hydrogen for ten filled-NBR, including neat NBR, are determined in an exposed pressure range of 1.3 MPa~92.6 MPa. Filler dependence on hydrogen uptake and diffusion is distinctly observed in the NBRs blended with high abrasion furnace (HAF) carbon black (CB) fillers compared to NBRs blended with medium thermal furnace (MT) CB and silica filler, which is related to the specific surface area of carbon black and interface structure. The HAF CB filled-NBR follows dual sorption behavior combined with Henry’s law and the Langmuir model, responsible for two contributions of solubility from polymer and filler. However, a single gas sorption behavior coming from the polymer is observed satisfying Henry’s law up to 92.6 MPa for NBR blended with MT CB filled-NBR and silica filled-NBR. Diffusion demonstrates Knudsen and bulk diffusion behavior below and above, respectively, at certain pressures. With increasing pressure, the filler effect on diffusion is reduced, and diffusivity converges to a value. The correlation observed between diffusivity and filler content (or crosslink density) is discussed.

“…As discussed in the introductory sections, the content and nature of groups vary according to the preparation methods. Among the different types of CB, channel black has the highest amounts of oxygen, typically varying between 3-8 wt.%[13,[97][98][99][100][101][102][103][104][105][106]; most CB have significantly lower surface functional groups, thus requiring harsher chemical conditions to form new C-C bonds or oxidation to allow for the grafting of species bearing different functional groups. The latter reactions are of great importance, as channel black has no longer been produced in the United States and in most other countries since the 1960s.…”

Carbon Black (CB) is one of the most abundantly produced carbon nanostructured materials, and approximately 70% of it is used as pigment and as reinforcing phase in rubber and plastics. Recent scientific findings report on other uses of CB that are of current interest, such as renewable energy harvesting and carbon capture. The present review focuses on the use and role of CB in renewable and environmental applications relevant to contemporary global challenges focusing specifically on clean energy. Key and recent research on the structure and chemistry of CB, including its uses as precursors to graphene quantum dots and hollow carbon spheres, is discussed in relation to renewable energy devices, electrochemical energy storage and environmental remediation. The surface chemistry of CB is closely related to that of graphitic and of turbostratic carbons through the predominant hexagonal carbon lattice from graphene fragments forming its basic structural units. Consequently, modern methods for grafting polymers and functional groups are easily translated to this abundant nanostructured material. Moreover, recent advances in electron microscopy that probe the structure of CB, and its electronic and physicochemical properties in nanocomposites revived the attention of what is wrongfully considered as a scientifically uninspiring material with limited potential for future technology breakthrough. CB has the potential to surge as a key player in renewable energy and environmental applications, meaning "When Black Turns Green".
