New Methods of Carbon Black Surface Modification
Abstract:The modification of the surface of carbon black is an important tool to adjust its material properties for different applications. Besides the well-known oxidation processes some new routes of surface modification were established in the last couple of years. The main feature of these new technologies is the formation of a chemical bond between the carbon black and the modification agent.
This paper is intended to give an overview on new modification methods which lead to a wide range of different types of carbon black. These technologies, e.g. polymer grafting, reactions with diazonium salts and radical initiators, open up the opportunity to influence the material surface, giving rise to changes from intense hydrophilic to strong hydrophobic.
An effective tool to attach modification agents on the carbon black surface is the well-known chemistry by Otto Diels and Kurt Alder. First published 75 years ago the socalled Diels-Alder reaction became a key also to new types of carbon blacks. With this reaction type it is possible to create products with variable polarities between hydrophilic and hydrophobic in order to tailor solutions for applications with special requirements. For this development the availability of new characterization methods like special DRIFTS and NMR analyses played an important role.
The main targets for the commercial use of these new products are NIP (non-impact printing) applications like ink jet and electrophotography, along with coating applications.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
