Effect of particle size in Ni screen printing paste of incompatible polymer binders

Rheological analysis of ceramic pastes with ethyl cellulose for screen-printing

“…When particles are dispersed in a polymer-solution matrix, the highand low-frequency behaviors report on the polymer-solution matrix and the microstructural details of the particle dispersion, respectively [10]. Fig.…”

“…This material can be used to prepare SOFC cathodes, and we have been trying to control the density and thickness of La 0.6 Sr 0.4 Ti 0.3 Fe 0.7 O 3 À δ films using screen-printing techniques [5,6]. For industrial screen printing using ceramic pastes, a polymer-ethyl cellulose (EC) for example--is generally combined with an organic solvent [5][6][7][8][10][11][12]. EC is popular in industry as it affords good printing and leveling.…”

Printing nanostructured carbon for energy storage and conversion applications

“…Of these, ink rheology has the greatest effect and is the most important parameter to control. The ink viscosity and viscoelasticity are affected by the particle size [42], solid loading concentration [43], and inclusion of additives such as binders and dispersants [44]. It is critical to tune the binder concentration to ensure high quality prints.…”

Understanding the Rheology of Screen-Printing Inks for the Fabrication of SOFC Thick Films

“…In contrast, an ink with a high G" value tends to show liquid-like properties and consequently lead to slumping and ink bleeding (4,6,12). These properties depend on many factors such as the particle size of the powder (4,13,14), solid loading (6,8,15) and, importantly, the composition of the ink which generally comprises a binder, a dispersant and an organic solvent (5,8,15,16), in addition to the powder.…”
