Abstract
A method of making tailored carbon black in a plasma process. A method of making tailored carbon black in a plasma process is described, including subjecting the carbon black particles during and/or after formation to surface functionalizing agents in a controlled manner so as to impart a degree and/or density of functionalization onto the carbon black particles so as to adapt the particles to a particular pre-intended application.
Claims13
A method of forming a functionalized carbon particle, comprising:
- (a) in a thermal plasma process reactor, forming a carbon particle in an atmosphere comprising hydrogen and substantially free of oxygen, wherein the carbon particle is substantially free of surface oxygen functional groups;
- and
- (b) in the thermal plasma process reactor, subjecting the carbon particle to a functionalization agent, thereby functionalizing a surface of the carbon particle to generate a functionalized carbon particle, wherein the subjecting is performed in a controlled manner.
