| 英文摘要 | Barocaloric solid-state refrigeration has aroused more attention since the breakthrough of plastic crystals. However, most reported materials with a single-phase transition generally exhibit a narrow working-temperature span. Herein, the layered C8H17NH3Cl compound is reported and shows a sequence of phase transitions from the initial triclinic phase to the final tetragonal phase near room temperature. These multiple-phase transitions result in a broad working-temperature span (Delta T) of similar to 65 K and a maximum isothermal entropy change of 119 J kg-1 K-1 under a pressure of 100 MPa. Simultaneously, Delta T is 25 K with a constant isothermal entropy change of 50 J kg-1 K-1 under the pressure of 100 MPa. The resultant refrigerant capacity is 3101 J kg-1. Raman analysis indicates that the molecular conformation disorder induced by the sequence of phase transitions is responsible for the excellent colossal barocaloric effect. This work not only indicates that the layered C8H17NH3Cl compound could be a promising competitor for barocaloric refrigeration near room temperature but also recommends that the multiple phase transitions are an effective route to broaden the working-temperature span. |
