Morphology of Toner-Silica Interfaces
Abstract:In this study Scanning Force Microscopy (SFM) is used for the investigation of toner particles and toner-silica particle interfaces. The focus is on the simultaneous mapping of topographic features and material properties like local stiffness and adhesion. Topographic images of toner particles of different toner binder compositions were recorded in addition with phase images of hard and soft domains. A series of toner – silica blends were prepared by using a common powder blender. The toner binder resin is styrene acrylics or polyester, respectively. In the topographic images the toner surface is mapped as a rough surface. The mapping of the elastic signals of the silica free toner surface reveals the arrangement of hard and soft domains. With this technique single silica aggregates have been imaged at the toner surface mainly located on topographic rough spots.

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.
