WebThe resulting polymer was structurally characterized and proven permanently porous with a surface area of 305 m2 g−1. The high concentration of amines (–NH– and –NH2) within the backbone of the polymer result in exceptional selectivity (141) for CO2 over N2 and dynamic capacity (15.1 cm3 g−1) in the presence of water (20 : 80 v/v CO2 : N2, 91% relative … 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. 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).
