Smart Capsules: Engineering New Temperature and Pressure Sensitive Materials with Microfluidics

ORAL

Abstract

New smart materials that are responsive to external stimuli such as pressure and temperature can be carefully designed using microfluidics with double emulsions as building blocks. Here we introduce the synthesis of new smart core-shell structures with two different aqueous drops in the interior. By triggering the capsules with pressure and temperature, coalescence and mixing of the interior drops occurs and is studied with high speed video imaging techniques.
