Progress in drying technology for nanomaterials

Production of nanomaterials is becoming increasingly important as a result of diverse industrial applications. Nanomaterials can be prepared by a dry process or a wet process; the latter involves drying, which affects the quality of the products. This article presents an overview of recent research and development activities in drying of nanomaterials. Current drying methods for such applications are classified and compared with the help of some examples. Selection criteria for drying methods as well as future research requirements are suggested.
