"easily adjust the temperature at which the anisotropy changes occur, and thus change the speed of heat transmission from the polymer... adjusted transition temperature over the range of 90 degrees Celsius to 147 degrees Celsius by judicious choice of the mesogen," says senior author Yoshiaki Nakamura. Conductivity-switching fully reversible, difference between on and off state approximately 2, comparable to the conventional values of various thermal switch reported in the preceding studies"
