Improved Polymers for Gas-Separation Membranes (8 of 9)

Caption

This shows the simple process to make a self-standing film of the new polymer used in this study. Steps, from left to right: 1-Mix the monomer, dimethoxymethane in trifluoroacetic acid and leave until viscous. 2-Pour into water. 3-Wash with water. 4-Cast from solvent into film. This image relates to a paper that appeared in Jan. 18, 2013, issue of Science, published by AAAS. The paper, by Mariolino Carta at Cardiff University in Cardiff, UK, and colleagues was titled, “An Efficient Polymer Molecular Sieve for Membrane Gas Separations.”
