Replication Data for: Largely Lowered Transition Temperature of a VO2/Carbon Hybrid Phase Change Material with High Thermal Emissivity Switching Ability and Near Infrared Regulations

Vanadium oxide (VO2) as a phase changing material possesses abrupt infrared (IR) transmission and thermal emissivity changing during the metal-insulator transition (MIT) across transition temperature (τc) of 68 °C. However, the high τc, moderate IR transmission and emissivity regulating ability limits its applications in various fields. We report a VO2/carbon hybrid phase change material fabricated via homemade plasma enhanced chemical vapor deposition (PECVD). The material shows a best reported thermal emissivity contrast (0.44) among the experimental value, a largely lowered τc (45 °C), promising near IR-regulation ability with enhanced photothermal effect in smart windows applications. The theoretical calculation results proved that the improvement of emissivity contrast is due to the hybridization of carbon. This work provides a new approach to synthesis VO2 hybrid material which have wide application in camouflage, sensing and smart windows.
