ALLVAR Alloy 30 is unique with a negative thermal expansion coefficient of −30 ppm/°C at room temperature, or a 1-meter rod shrinking by 0.003 mm for every degree Celsius rise.

Their closely matched experimental observations of the material’s thermal expansion, providing them with key insights into why the material has a negative thermal expansion in just one direction. “Our ...

Thermal expansion (or contraction) causes the nematic liquid crystal to flow; the flow imposes a realigning torque on the nematic liquid crystal molecules and the optic axis.
