Figure 4: The electrical conductivity of three other suspensions.

From: Reversible temperature regulation of electrical and thermal conductivity using liquid–solid phase transitions

Figure 4

(a) 1% graphite/water suspension. The electrical conductivity decreases about 24 times from −0.5 to 0.5 °C. (b) 1% carbon nanotube/hexadecane suspension. The electrical conductivity decreases about 40 times from 17.5 to 18.5 °C. (c) 0.4% graphite/polyethylene glycol 400 suspension. Polyethylene glycol 400 (Alfa Aesar) has a melting point between 4 and 8 °C and does not form a crystalline solid. Consequently, no large variation in the electrical resistivity was observed.
