“…This polymer has one of the lowest glass transitions16 and highest gas permeability coefficients 17. The crosslinking of linear PDMS chains to produce elastomeric networks can be performed by different processes, such as (1) γ radiation, (2) radical initiators, (3) polycondensation reactions of Si (CH 3 ) 2 OH end groups with silicon alkoxides, and (4) addition reactions such as hydrosilylation 18–22…”

In this investigation, the preparation and characterization of partially pyrolyzed membranes based on poly(dimethylsiloxane) (PDMS) are described. These membranes were obtained by the crosslinking of silanol‐terminated PDMS with multifunctional nanoclusters derived from the reaction of pentaerythritoltriacrylate with 2‐aminoethyl‐3‐aminopropyltrimethoxysilane and the in situ polycondensation of tetraethylortosilicate, followed by the thermal treatment of the resulting membranes at different temperatures. The partially pyrolyzed membranes were characterized with infrared spectroscopy, thermogravimetry, elemental analyses, dynamic mechanical analysis, small‐angle X‐ray scattering, and scanning electron microscopy. The membranes exhibited improvements in the thermal stability and mechanical strength. Even with distinct compositions with respect to the Si/O and Si/C ratios, the flexibility of these materials was maintained. The flux rates of the gases through the membranes were measured for N2, H2, O2, CH4, and CO2, at 25 °C. The permeability of the membranes changed with increases in the pyrolysis and oxidation temperatures. These membranes could be described as PDMS chains separated by inorganic clusters. © 2006 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 45: 299–309, 2007.

“…Soufyani et al [174] found that the aging time (t ag ) of the initial solution is an important parameter for the elaboration of efficient silica membranes. A thin film of a hybrid material prepared from TiO 2 -SiO 2 and silicone (PDMS) using the sol-gel technique was formed on the surface of α-alumina.…”

The atmospheric concentration of anthropogenic carbon dioxide (CO 2 ) has been increasing since the start of industrialization in the mid 19th century, and the rate is increasing. It is highly unlikely that fossil fuel combustion, the main contributor to anthropogenic CO 2 , will be replaced in the foreseeable future. Therefore, CO 2 capture and storage offer a new set of options for reducing greenhouse gas emissions, in addition to the current strategies of improving energy efficiency and increasing the use of renewable energy resources. Carbon dioxide selective membranes provide a viable energy-saving alternative for CO 2 separation, since membranes do not require any phase transformation. This review examines various CO 2 selective membranes for the separation of CO 2 and N 2 , CO 2 and CH 4 , and CO 2 and H 2 from flue or fuel gas. This review attempts to summarize recent significant advances reported in the literature about various CO 2 selective membranes, their stability, the effect of different parameters on the performance of the membrane, the structure and permeation properties relationships, and the transport mechanism applied in different CO 2 selective membranes. Finally, the future direction for CO 2 selective membranes is proposed. Hybrid organic-inorganic membranes have become an expanding field of research, as the introduction of organic molecules can improve the characteristics of a matrix. Hydrotalcite-type materials, perovskite-type oxides, lithium zirconate, and lithium silicate are also suggested as candidate materials for high temperature CO 2 selective membranes.
