Some Singularities of Polysterene Adsorption on Technical Carbon
Abstract:Investigation of filled composite materials is connected with polymer adsorption on a solid surface. Studies of adsorption from polymer solutions on solid surfaces are mainly aimed at revealing how the value of adsorption depends on the thermodynamic quality of the solvent, polymer concentration in the solution, molecular mass and molecular-mass distribution of polymer, temperature, nature of adsorbent, and surface charge and charge density, in polyelectrolytes. The adsorption systems containing macromolecules and dispersed particles of the solid phase are rather complex, because they have features of both lyophobic and lyophilic disperse systems.
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 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.
