Lamellar Membranes

This book chapter gives a comprehensive review of two-dimensional (2D) nanomaterials that provide tremendous potential for separation applications. By using 2D nanomaterials as a building block, various types of lamellar membranes are actively investigated. In lamellar membrane, the mass transport occurs through the inherent interplanar spacing of the nanomaterials and the nanochannels generated during the fabrication of lamellar membranes. However, the trade-off between permeability and selectivity in membranes is inevitable. Different strategies such as interlayer channel aperture, membrane nanopores, and appropriate functionalization can bridge this trade-off. Various routes for preparing lamellar membranes including 2D nanosheet synthesis strategies, assembling techniques, mechanisms involved in transportation, and regulation of nanochannels are discussed in detail.
