Some Singularities of Polysterene Adsorption on Technical Carbon
We studied adsorption of polystyrene with molecular mass 5.7 × 105 from a solution in toluene on three samples of commercial-grade carbon: TM-15, TM-50, and TM-75 with specific surface area equal to 15, 50 and 75 m2/g, respectively, under various experimental conditions. The carbon powder was preliminarily dispersed in a particular volume of solvent, and this dispersion was mixed with an equal volume of solution and a double concentration of polymer.
Preliminary dispergation of technical carbon in solvent influences on an adsorption process. In this connection the solvent concentration, under which non-separated technical carbon particles are appeared, is decreasing.

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.
