Sprayed separation membranes: A systematic review and prospective opportunities

Abstract

Membrane separation technology has been taken up for use in diverse applications such as water treatment, pharmaceutical, petroleum, and energy-related industries. Compared with the design of membrane materials, the innovation of membrane preparation technique is more urgent for the development of membrane separation technology, because it not only affects physicochemical properties and separation performance of the fabricated membranes, but also determines their potential in industrialized application. Among the various membrane preparation methods, spray technique has recently gained increasing attention because of its low cost, rapidity, scalability, minimum of environmental burden, and viability for nearly unlimited range of materials. In this Review article, we summarized and discussed the recent developments in separation membranes using the spray technique, including the fundamentals, important features and applications. The present challenges and future considerations have been touched to provide inspired insights for developing the sprayed separation membranes.
