Laser Patterning of Porous Support Membranes to Enhance the Effective Surface Area of Thin-Film Composite-Facilitated Transport Membranes for CO Separation.

Although thin-film composite membranes have achieved great success in CO separation, further improvements in the CO permeance are required to reduce the size and cost of the CO separation process. Herein, we report the fabrication of composite membranes with high CO permeability using a laser-patterned porous membrane as the support membrane. High-aspect-ratio micropatterns with well-defined micropores on their surface were carved on microporous polymer supports by a direct laser writing process using a short-pulsed laser.

Imidazole tailored deep eutectic solvents for CO2 capture enhanced by hydrogen bonds.

Deep eutectic solvents (DESs) have emerged as promising alternative candidates for CO2 capture in recent years. In this work, several novel DESs were firstly prepared to enhance CO2 absorption. Structural and physical properties of DESs were investigated, as well as their absorption performance of CO2.
