We are supported by NSF and PRF-ACS and equipped with a broad spectrum of experimental tools, ranging from rheological, rheo-optical instruments and flow birefringence methods to the recently in-house developed powerful particle tracking velocimetry that can be applied to a variety of setups to probe the shear flow behavior of polymer solutions and melts.
Major equipment in the group includes:
- ARES rheometer with rheo-optics,
- Advanced FTIR imaging spectroscopy,
- Bohlin-CVOR (stress-controlled rheometer) with home-made transparent cone/plate and Couette flow cells for rheo-optical measurements,
- Anton Paar MCR 301 (stress-controlled rheometer),
- Custom-made linear shear (force-controlled) rheometer for studying polymer melt flow,
- Custom-made sliding plate rheometer (operating in either force-controlled or displacement-controlled mode) with optical windows to allow light through both velocity gradient and vorticity directions respectively,
- Custom-made tearing and stretching device (force-controlled),
- Two Monsanto Automatic Capillary Rheometers with home-designed slit die for optical measurements,
- Goettfert Capillary Rheometer (RheoTester-1000) with home-designed slit die for flow visualization.
