Abstract:
1. A method for forming functionalized carbon black useful for uniform dispersion in a surface material of printing system components, comprising: providing carbon black; providing a fluoropolymer having a terminal amino group; and mixing the amino-terminated fluoropolymer and the carbon black, wherein in the fluoropolymer is amino-terminated PDMS; providing nitric acid; mixing the carbon black with the nitric acid to oxidize a surface of the carbon black whereby oxidized carbon black is formed; washing the oxidized carbon black with deionized water until a pH of the carbon black in solution is 5; drying the carbon black using vacuum at 150 degrees Celsius for one hour; the mixing the amino-terminated fluoropolymer and the carbon black further comprising the carbon black being the vacuum dried, oxidized carbon black, the amount of dried, oxidized carbon black lying in a range of 0.5 g to 1.0 g, the amount of amino-terminated fluoropolymer being 10 g, and an amount of the coupling agent being 1 g.
