Micro/nano rare earth compounds have been paid much attention by many experts due to their special physical and chemical properties. By means of controllable synthesis of micro-morphology and particle size,it can expand the application field and enhance the added value of micro/nano rare earth compounds. At present,the separation and extraction technology of Rare earth in China are far ahead of other countries,but it is still need to be improved for the controllable synthesis and reasonable application of micro/nano rare earth compounds. In this paper,the preparation methods have been reviewed and compared which including solid phase and liquid phase in synthesis of the micro/nano rare earth compounds. Finally,the applications of micro/nano rare earth compounds in the field of polymer materials were analyzed and discussed from some aspects such as heat stabilizer,flame retardant,reinforcing agent and antibacterial antiseptic,which provides ideas for further research and application of micro/nano rare earth compounds.
