High Performance Polymer for Gas Separations.

Compatibilized Immiscible Polymer Blends for Gas Separations

Membrane-based gas separation has attracted a great deal of attention recently due to the requirement for high purity gasses in industrial applications like fuel cells, and because of environment concerns, such as global warming. The current methods of cryogenic distillation and pressure swing adsorption are energy intensive and costly. Therefore, polymer membranes have emerged as a less energy...

TCAQ - based polymer for electrochemically mediated separations

Redox-mediated separation systems offer the potential to efficiently desalinate water and to purify contaminated waste streams, among other health and environmental applications. A TCAQ-based polymer, unique for its two-electron redox reaction, was synthesized for use in redox-mediated separation systems, and its performance was quantified in low-concentration aqueous salt solutions. The polyvi...

SEM, TEM, and AFM Analyses of Phase-Separated Polymer Blend Membranes for Gas Separations

Polymer blends are proving to be important in emerging technologies including as gas separation membranes [1]. The blending of existing polymers offers the distinct advantage of being able to develop new materials with potentially synergistic properties not attainable with the individual polymer components and without the need to synthesize new macromolecules [2]. We recently developed phasesep...
