Preparation of Macro-RAFT Copolymer and its Application in Pigment Dispersion for Inkjet Inks
With hydrophobic and hydrophilic units, the macro-RAFT copolymers have the potential ability to disperse pigment. Organic phthalocyanine blue pigment (P.B.15:3) was dispersed with the macro-RAFT copolymers by vigorously stirring and ultrasonic processing. The properties (particle size, polydispersity index) of pigment dispersions were measured. It was shown that the particle size and distribution (PDI) has relationship with ultrasonication time and the amounts of macro-RAFT copolymers. The results showed that the particle size and PDI of pigment dispersions dispersed with macro-RAFT copolymer were smaller than that of dispersed with sodium dodecyl sulfate (SDS).

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
