Intelligent Materials having Self-Judgment Ability
Creation, research and design of intelligent materials having the ability
to control own propaties by sensing the external environmental stimuration,
such as heat, temperature and pressure, and change the structures.
Recently we are now researching about the thermal rheological(TR) fluid,
which shows the reversible rheological propaties with increasing temperature
viscosity increase and vice verse.
Video shows the change in flow behavior of concentrated PE particle dispersions
when injected the dispersant we are now studying.

The Video prezents the function of thermal rheological fluid, the viscosity changes with temperature.
(In the heating process, near 44.6°C (1:37), upper screw will move togather, and the cooling process, near 39.8°C (4:13), the upper screw stopps again.)
