- Additional information:
- Carbon black is an engineered material, primarily composed of elemental carbon, obtained from the partial combustion or thermal decomposition of hydrocarbons. It exists as aggregates of aciniform morphology (i.e. shaped like a cluster of grapes) which are composed of spheroidal primary particles. While the fundamental building block of carbon black is the primary particle, these never exist in isolation, but are strongly fused by covalent bonds into aggregate. The primary particles are thus conceptual in nature since once the aggregate is formed the primary particles no longer exist as discrete entities and have no physical boundaries among them. Once produced, individual aggregates join together by van der Waals forces to form agglomerates. Agglomerates do not break down into smaller components unless adequate force is applied (for example, shear force). Primary particle and aggregate sizes are distributional properties and vary depending on the carbon black grade. Transmission electron micrographs demonstrate that while primary particle and aggregate sizes vary greatly within a given grade of carbon black, the primary particle size is essentially uniform within an individual aggregate.

- Post-production, some nanoforms of the set carbon black (solid: nanoform, no surface treatment) are subjected to oxidative after-treatment. The treatment augments the level of already present acidic and polar oxides on the surface of carbon black. These functional groups render these forms more hydrophilic in comparison to the corresponding virgin non-oxidized form; meaning that the carbon black particles becomes better dispersible and wettable in polar solutions but are still completely insoluble. Surface treatment does not affect the morphological features i.e. primary particles, aggregates, and agglomerates of carbon black.

Surface treatment
- Order:

- External layer:

- Description:
- - Main features of the surface treatment/functionalisation process: Carried out in fluidized bed reactors. This is a two step process. Carbon black is oxidized with nitrogen oxide/air mixture. In the second step, NO2 absorbed on the surface of the carbon black is desorbed by treatment with hot air.
- the type of process/reaction: oxidization
- relevant ranges of process parameters such as reaction conditions (pH, temperature): between 200 -300°C
- any purification step: no
- Functionalities introduced by the treatment: Carboxylic, hydroxylic, lactonic, quinonic, basic oxides
Following the oxidisation procedure, the carbon black particles are subjected to a treatment with hot air; hot air (@ ca. 300°C) is blown for several hours through the layer of carbon black. This step removes any remnants of treatment agent that may have been trapped within the layers of carbon black during oxidation. - Percentage of coverage of particle surface, %:

- Surface treatment name:
- Oxidisation with ozone
Surface treatment
- Order:
- #1
- External layer:
- hydrophobic
- Description:
- The main post-production treatment of carbon black is oxidative after-treatment. The surface of carbon black is oxidized by placing it in contact with an oxidant (such as nitric acid, nitrogen oxides, ozone, etc.) that may be in gas or liquid form. Following oxidative treatment, the surface of carbon black experiences a pH shift towards more acidity due the augmentation of acidic and polar oxides on the surface of carbon black. This makes the oxidized form more hydrophilic in comparison to virgin non-oxidized form; meaning that the carbon black particles becomes more dispersible in water but are still completely insoluble. It is important to note that untreated and oxidised forms of carbon black exhibit the same types of functional groups on their surface; albeit levels may be increased several folds following oxidization.
- Main features of the surface treatment/functionalisation process:
Carried out at room temperature by passing a gas produced in an ozonizer through a layer of carbon black. Ozidization occurs in fluidized bed reactors, or stirred stationary bed reactors in which the carbon black is continuously kept in motion
- the type of process/reaction: oxidization
- relevant ranges of process parameters such as reaction conditions (pH, temperature):
room temperature
- any purification step:
no
- Functionalities introduced by the treatment: Carboxylic, hydroxylic, lactonic, quinonic, basic oxides
Following the oxidisation procedure, the carbon black particles are subjected to a treatment with hot air; hot air (@ ca. 300°C) is blown for several hours through the layer of carbon black. This step removes any remnants of treatment agent or free radicals that may have been trapped within the layers of carbon black during oxidation. Further, O3 is very unstable and decomposes rapidly to O2 - Percentage of coverage of particle surface, %:

It exists as aggregates of aciniform morphology (i.e. shaped like a cluster of grapes) which are composed of spheroidal primary particles. While the fundamental building block of carbon black is the primary particle, these never exist in isolation, but are strongly fused by covalent bonds into aggregate. The primary particles are thus conceptual in nature since once the aggregate is formed the primary particles no longer exist as discrete entities and have no physical boundaries among them. Once produced, individual aggregates join together by van der Waals forces to form agglomerates. Agglomerates do not break down into smaller components unless adequate force is applied (for example, shear force). Primary particle and aggregate sizes are distributional properties and vary depending on the carbon black grade. Transmission electron micrographs demonstrate that while primary particle and aggregate sizes vary greatly within a given grade of carbon black, the primary particle size is essentially uniform within an individual aggregate.
