Energy-efficient polymeric gas separation membranes for a sustainable future: A review WebA polymer of intrinsic microporosity (PIM-1) containing nitrile groups was reacted by [2 + 3] cycloaddition reaction to give a polymer substituted with tetrazole groups (TZ-PIM), and then was further methylated to give a new PIM substituted with methyl tetrazole groups (MTZ-PIM). In contrast to TZ-PIMs, the MTZ-PIMs had distinctly improved solubility …

WebThe intrinsic porosity of plasma deposited SiO x thin films onto polydimethylsiloxane (PDMS) polymers can be controlled by plasma preconditioning of the PDMS before deposition. Oxidising plasma treatment of the PDMS results in the conversion of the top PDMS into a SiO x ‐like surface onto which additional SiOx is deposited.
