| Abstract | Magnetic graphite nanofiake (GN) suspensions with reversible thermal conductivity (TC) are reported. A process of sulfuric acid intercalation, microwave expansion magnetization, and ultrasonic dispersion is followed to make magnetic GN Poly-Alpha-Olefin (PAO) suspensions. Magnetic field was observed to increase the TC of the suspensions dramatically, up to 325% with 0.8% (w/w) of magnetic GNs. After removing the magnetic field, the TC trends to decrease reversibly. The maximal TC contrast ratio reaches 3 times before and after the effects of magnetic field. Such riiaterials with magnetically reversible TC have great potential in next generation "smart" cooling devices. (C) 2015 Elsevier B.V. All rights reserved. |
