Polymers of intrinsic microporosity
WebMiscible blends of Matrimid and carboxylated polymers of intrinsic microporosity (cPIM-1) at the molecular level have been discovered. Their miscibility has been confirmed by polarized light microscopy (PLM), atomic force microscopy (AFM), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction …

WebHigh performance polymer dielectrics are a key component for printed electronics. In this work, organo-soluble polymers of intrinsic microporosity (PIMs) are reported for the first … 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 …
