Enormous CO2 Sorption Capacity of PDMS Rubbers near Condensation Pressure and at Low Temperatures
We report for the first time that PDMS rubber sorbs an extremely large amount of CO2 (792 mg g−1) at near the condensation pressure at a certain low temperature (−3 °C), giving the sorption enthalpy of 9.3–10.8 kJ mol−1. The sorption isotherms were evaluated by means of the Flory–Huggins equation, a...

| description | We report for the first time that PDMS rubber sorbs an extremely large amount of CO2 (792 mg g−1) at near the condensation pressure at a certain low temperature (−3 °C), giving the sorption enthalpy of 9.3–10.8 kJ mol−1. The sorption isotherms were evaluated by means of the Flory–Huggins equation, and the resultant χ parameters (1.3–0.2) were used to estimate the solubility parameter (SP). The CO2/CH4 and CO2/N2 selectivities were 9.6–44 at 100–3000 kPa and were far larger than those of activated carbon. |
