“…Itta et al preferred to dry PPO/PVP and CMS membrane films at room temperature for one day [52] as well as Tseng et al [53] who dried PI or PEI/CMS MMMs also at room tem-perature. Another team of researchers used room temperature for drying the Matrimid®/ CMS MMM followed by vacuum oven drying at 100°C overnight for removal of the complete solvent [54].…”

“…They adopted three methods for drying the cast film: (i) at room temperature for one day, (ii) under atmospheric pressure with nitrogen atmosphere at 60°C -80°C for almost 10 h, (C) under partial vacuum with nitrogen circulation at 60°C -80°C for 8-10 h. Methods (a) and (b) were also carried out in quenching and annealing processes [37].

Material Advancements in Fabrication of Mixed‐Matrix Membranes

The mixed-matrix membrane (MMM) is a new membrane material for gas separation and plays a vital role for the advancement of current membrane-based separation technology. Blending between inorganic fillers like carbon molecular sieves, zeolite, metal oxides, silica and silica nanoparticles, carbon nanotubes, zeolitic imidazolate framework, metal organic framework, and glassy and rubbery polymers etc. is possible. Due to mechanical, thermal, and chemical stability, these membranes achieve high permeability and selectivity as compared to pure polymeric materials. Despite of these advantages, the MMM performances are still below industrial expectations because of membrane defects and related processing problems as well as the nonuniform dispersion of fillers in MMMs. Material selection for organic and inorganic phases, preparation techniques, material advancements, and performance of MMMs are discussed. Issues and challenges faced during MMM synthesis as well as problem solutions are highlighted.

“…The concept of polymer blends was first proposed by Ozaki et al [5]. Since then, a lot of similar efforts were reported such as polyimide/polyvinylpyrrolidone (PI/PVP) [2], phenol formaldehyde novolac resin polyethylene glycol (PFNR/PEG) [6], polyetherimide (PEI)/PVP [7][8][9], poly(p-phenylene oxide (PPO)/PVP [10], polybenzimidazole (PBI)/PI [11], and PI/PEG [12].…”

Carbon Membranes Prepared from a Polymer Blend of Polyethylene Glycol and Polyetherimide

2016

View full text Add to dashboard Cite

Through a dip-coating technique, carbon membranes were produced from a polymer blend consisting of the thermally stable polymer polyetherimide (PEI) and the thermally labile polymer polyethylene glycol (PEG). The PEG/PEI carbon membranes were synthesized on an alumina support coated with an Al 2 O 3 intermediate layer. The polymer blend ratio and carbonization temperature influenced the structure and permeation performance of the derived carbon membranes. The porosity of the PEG/PEI carbon membranes increased with higher PEG content in the blends. However, the derived carbon membranes tended to lose gas permeability with raising the carbonization temperatures. The carbon membranes were successfully optimized in order to achieve the highest CO 2 /CH 4 and CO 2 /N 2 selectivities.
