One-Piece Micropumps from Liquid Crystal Elastomer Core-Shell Particles |
| 초록 |
Responsive polymers are low-cost, light-weight, and flexible and thus an attractive class of materials for the integration into micromechanical and lab-on-chip systems. Triggered by external stimuli, liquid crystalline elastomers are able to perform mechanical motion and can be utilised as microactuators. We present the fabrication of one-piece micropumps from liquid crystalline core-shell elastomers via a microfluidic double-emulsion process. Due to the continuous nature of the deployed microfluidic setup, the fabrication process makes a low-cost production with a high throughput accessible. The elastomer particles are filled with a liquid core, which is reversibly pumped into and out of the particle by actuation of the liquid crystalline shell in a jellyfish-like motion. The LCE shells have the potential to be integrated into a microfluidic system as micropumps for flow regulation. |
