<p>The present invention relates to a method of treating a surface comprising a silicone elastomer having a plurality of Si—H groups by contacting at least one region of the surface with a solution comprising a surface treatment compound, to give a treated surface with Si—OH, Si—OR, or Si—C groups. The present invention relates to a hydrosilylation-curable silicone composition. In some examples, the hydrosilylation-curable silicone composition includes an organohydrogen-polysiloxane having an average of at least forty silicon-bonded hydrogen atoms per molecule, a cross-linking agent having an average of at least two aliphatic unsaturated carbon-carbon bonds per molecule, and a hydrosilylation catalyst, wherein the mole ratio of silicon-bonded hydrogen atoms in the composition to aliphatic unsaturated carbon-carbon bonds in the composition is at least 20:1. The invention also relates to membranes, methods of making membranes, gas permeable supports for membranes, and methods of gas separation using membranes.</p> |
