英文摘要：

Tourmaline is one of the most important silicate minerals in the group of non-metallic minerals as a non-renewable natural mineral. The tourmaline crystal has distinctive characteristics including complex chemical composition, polymorph and color diversity. Tourmaline presents pyroelectric, piezoelectric, spontaneous polarization and negative ionreleasing, which originate from its composition and structural properties. In recent years, it has become a hot topic to prepare various functional composites utilizing tourmaliners environmental functionalities. This paper provides a summary over the unique physical and chemical properties, and en- vironmental functionalities of tourmaline, based on its origin, classification, crystal composition and microstructure. Furthermore it describes tourmaline＇s various applications in the fields of environmental pollution and relevant key issues, also makes a prospect on the development of tourmaline functional composites.
