Abstract

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 FeO. In addition, the characterizations exhibit the excellent magnetic and phase change properties. The magnetic MicroPCMs samples present 20 emu·g saturation magnetization with still high enthalpy of 132 J·g, which fully illustrates that the magnetic MicroPCMs fulfill both application on thermal energy storage and magnetic control.

摘要

磁性微胶囊相变材料（磁性微PCM）因其具有相变和磁性的双重功能而受到广泛研究，这为其在可控相变材料和红外电磁双屏蔽领域提供了新的应用。通过聚合和共沉淀法合成了一系列磁性微PCM样品，其化学成分包含由FeO改性的聚（MMA-MAA）@正十八烷。此外，表征显示出优异的磁性和相变性能。磁性微PCM样品呈现出20 emu·g的饱和磁化强度，同时仍具有132 J·g的高焓值，这充分说明磁性微PCM在热能存储和磁控方面均能实现应用。
