Zusammenfassung:The invention discloses a dual-mode thermal management device and a preparation method thereof, and belongs to the field of nanometer materials and application. Dioctyl phthalate modified poly (4-methyl-1-pentene) doped with titanium dioxide nanoparticles is used as a cooling layer of the device, a secondary shape memory polymer with a reversible shape memory effect is used as a driving layer, and an aluminum plate plated with chromic oxide nanoparticles is used as a heating layer. The dual-mode thermal management device prepared by the invention can spontaneously adjust the electromagnetic spectrum characteristics by sensing the temperature. In a heating mode, the average heating power density is 859.8 W/m < 2 > (the corresponding photo-thermal conversion efficiency is 91%); and in the cooling mode, the average cooling power density is 126.0 W/m < 2 >. No external energy consumption is generated in the whole working process. 本发明公布了一种双模式热管理器件及其制备方法,属于纳米材料与应用领域。使用掺杂有二氧化钛纳米颗粒的邻苯二甲酸二辛脂改性聚(4-甲基-1-戊烯)作为器件的冷却层,具有可逆
