Special Issue Information

Dear Colleagues,

Recent years have witnessed fruitful research on thin films and mixed matrix membranes, which have found usage as membranes, adsorbents, catalysts, sensors, etc. Further advancement for thin films or mixed matrix membranes relies on better understanding of the materials science, processing techniques and transport phenomena. With the discovery and development of new materials, such as diverse 2D materials and covalent organic frameworks (COFs), there are renewed interests in realizing new applications with them. New film fabrication techniques and insights offer new opportunities for high-performance materials. For example, zeolite membrane thickness limits were pushed forward from about one micrometer to a few nanometers over the past twenty years. It greatly improves membrane separation performances and opens new separation possibilities. Understanding the transport phenomena in the separation process is of paramount importance. Equilibrium and kinetic properties help rationalize materials design for optimized performance.   

A lot of interesting research has been conducted to address different issues faced by thin films or mixed matrix membranes for more separation or other applications. I would like to invite you to contribute original research articles, perspective or review articles to this Special Issue on the development of thin films or mixed matrix membranes.

All the best,

Dr. Shaowei Yang

There have been significant advancements in small-pore zeolite membranes in recent years. With pore size closely related to many energy- or environment-related gas molecules, small-pore zeolite membranes have demonstrated great potential for the separation of some interested gas pairs, such as CO2/CH4, CO2/N2 and N2/CH4. Small-pore zeolite membranes share some characteristics but also have distinctive differences depending on their framework, structure and zeolite chemistry. Through this mini review, the separation performance of different types of zeolite membranes with respect to interested gas pairs will be compared. We aim to give readers an idea of membrane separation status. A few representative synthesis conditions are arbitrarily chosen and summarized, along with the corresponding separation performance. This review can be used as a quick reference with respect to the influence of synthesis conditions on membrane quality. At the end, some general findings and perspectives will be discussed.
