Electric-Field-Controlled Adsorption of Microcapsules under Fabrication of Planar Structures

It is found that an electric field applied parallel to a substrate surface influences the adsorption of positively charged core–shell microcapsules on glass substrates. As a result, the amount of microcapsules adsorbed near negative contact is up to 2 times larger than the one absorbed near positive...

Summary:It is found that an electric field applied parallel to a substrate surface influences the adsorption of positively charged core–shell microcapsules on glass substrates. As a result, the amount of microcapsules adsorbed near negative contact is up to 2 times larger than the one absorbed near positive contact. It is also found that small concentration (less than 0.2 M) of salt in microcapsule suspension decreases this effect, while an increase in the concentration to 0.45 M results in enhancement of the effect.
