Abstract

Cover: The cover shows various aspects of ink-jet printing of polymers: a thickness library of films of electroluminescent polymer, ink-jet printing polymers on a MALDI target and a chainlike structure that remains after ink-jet printing a line of polymer-containing droplets. The foreground shows an ejected droplet of butylacetate with various satellite droplets.Further details can be found in the Communication by E. Tekin, E. Holder, V. Marin, B.-J. de Gans, and U. S. Schubert* on page 293.

Inkjet printing of carbon supported platinum 3-D catalyst layers for use in fuel cells

“…Because IJP methods are additive (reducing waste and processing steps) they have been evaluated for several multilayer devices including organic transistors, 3-D MEMs, biopolymer arrays, and photonic crystal microarrayes [11,12]. Other useful adaptations of IJP include applications in the following: combinatorial materials research, polymer light emitting diode displays, microcircuitry, life sciences, ceramics, and carbon nanotubes [13][14][15][16][17][18][19][20][21]. For fuel cell applications, this tech- nology resolves many of the problems associated with previous methods of catalyst deposition by allowing a uniform distribution of catalyst material onto the surface of the GDL (CCE) or electrolyte CCM (i.e.…”

Inkjet-printed gold nanoparticle chemiresistors: Influence of film morphology and ionic strength on the detection of organics dissolved in aqueous solution

“…Recent years have seen it become a fast-growing technique for the fabrication of light-emitting diodes [4,5], field-effect transistors [6] and chemiresistors [7,8] since the droplets can be deposited on-demand to any precise location. However, one commonly observed phenomenon after solvent evaporation from the droplet is the formation of a circular ring pattern ("coffee ring"-like structure) containing most of the solutes [9][10][11].…”

Combinatorial Screening of Polymer:Fullerene Blends for Organic Solar Cells by Inkjet Printing

“…Additionally, the parameters for fi lm preparation have a signifi cant infl uence on the properties of the active layer. [ 33,34 ] Therefore, an enormous number of samples need to be screened for the evaluation of promising polymer:fullerene combinations and good processing conditions. Instead of studying the potential materials in a sequential, one-by-one manner, for example by spin-coating, inkjet printing of thin-fi lm libraries allows a fast screening of many materials in parallel.…”
