Abstract: As a kind of sampling preparation method, solid phase microextraction (SPME) has many advantages such as simplicity, versatility, sensitivity and solvent free. It has gained widespread acceptance in separation and analysis. As the key factor of the SPME technique, coatings on SPME fiber determine the performance and application of SPME technique. Consequently, developing new coatings is the most important work for SPME. With the development of preparation methods of SPME coatings, many new coatings have appeared in recent years, and these new coatings expand the application fields of SPME technique. This review summaries the development of new SPME coatings in the past three years and mainly focuses on the preparation methods and properties of new SPME coatings.
