Flexible Polyacrylonitrile-Supported MOF-on-COF Composite Membrane for Hydrogen Purification.

Hydrogen (H) is a clean and efficient energy source that has garnered global technological development to enhance its production. However, effective purification is necessary to remove impurities from hydrogen products. H purification membranes need to exhibit both high H permeance and sufficient H selectivity.

The State-of-the-Art Functionalized Nanomaterials for Carbon Dioxide Separation Membrane.

Nanocomposite membrane (NCM) is deemed as a practical and green separation solution which has found application in various fields, due to its potential to delivery excellent separation performance economically. NCM is enabled by nanofiller, which comes in a wide range of geometries and chemical features. Despite numerous advantages offered by nanofiller incorporation, fabrication of NCM often met processing issues arising from incompatibility between inorganic nanofiller and polymeric membrane.

Tailoring the CO-selectivity of interfacial polymerized thin film nanocomposite membrane via the barrier effect of functionalized boron nitride.

Membrane-based separation is an appealing solution to mitigate CO emission sustainably due to its energy efficiency and environmental friendliness. Attributed to its excellent separation endowed by nanomaterial incorporation, nanocomposite membrane is rigorously developed. This study explored the feasibility of boron nitride (BN) embedment and changes to formation mechanism of ultrathin selective layer of thin film nanocomposite (TFN) are investigated.

Strategies in Forward Osmosis Membrane Substrate Fabrication and Modification: A Review.

Forward osmosis (FO) has been recognized as the preferred alternative membrane-based separation technology for conventional water treatment technologies due to its high energy efficiency and promising separation performances. FO has been widely explored in the fields of wastewater treatment, desalination, food industry and bio-products, and energy generation. The substrate of the typically used FO thin film composite membranes serves as a support for selective layer formation and can significantly affect the structural and physicochemical properties of the resultant selective layer.

Nanocomposite Membranes for Liquid and Gas Separations from the Perspective of Nanostructure Dimensions.

One of the critical aspects in the design of nanocomposite membrane is the selection of a well-matched pair of nanomaterials and a polymer matrix that suits their intended application. By making use of the fascinating flexibility of nanoscale materials, the functionalities of the resultant nanocomposite membranes can be tailored. The unique features demonstrated by nanomaterials are closely related to their dimensions, hence a greater attention is deserved for this critical aspect.
