Design the magnetic microencapsulated phase change materials with poly(MMA-MAA) @ n-octadecane modified by Fe3O4

Magnetic microencapsulated phase change materials (magnetic MicroPCMs) are hotly researched for their dual-functions with phase change and magnetic properties, which provided the new applications in fields of maneuverable phase change materials and infrared electromagnetic dual shield. A series of magnetic MicroPCMs samples are synthesized by polymerization and coprecipitation method and the chemical composition contained poly(MMA-MAA) @ n-octadecane modified by Fe 3 O 4 . In addition, the characterizations exhibit the excellent magnetic and phase change properties. The magnetic MicroPCMs samples present 20 emu·g −1 saturation magnetization with still high enthalpy of 132 J·g −1 , which fully illustrates that the magnetic MicroPCMs fulfill both application on thermal energy storage and magnetic control.
