ABSTRACT:
The present invention provides a method for making a hybrid composition membrane comprising the steps of preparing a sol comprising at least one poly(amino-alcohol) and at least one alkoxy silane, casting the sol on a surface and drying the casted sol to form the hybrid composition membrane. The hybrid composition membrane may be used for capturing and separating CO2and/or H2S from a gas sample.
