Abstract
'Smart' polymers are environmentally sensitive polymers that respond to small changes in environmental stimuli with large, sometimes discontinuous changes in their physical state or properties. We have been developing 'smart' microfluidic systems by using smart polymers that can receive device-generated signals and act as switches. Biodegradable semi-crystalline poly(epsilon- caprolactone) (PCL) is known to show temperature-responsive 'on-off' transition over its melting temperature and crosslinked PCLs have dual-shape capability, showing shape-memory effect. The work presented here demonstrates re-writable, shape-memory microfluidic channels using actively moving PCLs to facilitate the dynamic geometric changes and microfluidic flow control by local heating around a biological relevant temperature.
