摘要：
Liquid-solid phase change cycling stability is as important as its freezing/melting performance for nanosuspensions as phase change mate-rials, because nanoparticles tend to aggregate and settle down. However, it has been rarely studied. In this study, zirconium phosphate (ZrP) nanosuspensions with high dispersion stability is proposed as a novel phase change material. Its freezing/melting performance and cycling stability were compared with water and graphene (GN) nanosuspensions. Results showed that the subcooling degree (SD) of all the samples decreased with increased freezing/melting cycle. At the same freezing/melting cycle, the SD of the ZrP and GN nanosuspensions were reduced compared with water. The nanosuspensions with higher nanoparticle concentration exhibited lower SD. The results suggested that both the ZrP and GN nanoplatelets and ice crystals could induce nucleation in the nanosuspensions. In comparison with the GN nanosuspensions, the SD of the ZrP nanosuspensions was higher at 0.1wt% but lower at 1.0wt% particle concentration. Dispersion stabilities of both nanosuspensions after freezing/melting cycles were then compared. Results showed that compared with the GN nanosuspensions, the ZrP nanosuspensions had higher dispersion stability, thus were able to reduce SD more effectively. © 2019, Materials Review Magazine.
