In this study, a novel conducting MOFs/polymer hybrids were synthesis successfully. [BMIM]BF4 ionic liquid was first incorporated into UiO-67 and then the composite membranes were prepared by incorporating [BMIM]BF4@UiO-67 within polyacrylonitrile (PAN) matrix. The [BMIM]BF4@UiO-67/PAN membrane shows enhanced ionic conductivity (2.53 × 10−4 Scm−1 at 90 °C when the [BMIM]BF4@UiO-67 content is 60 wt %) under low humidity condition (35% relative humidity), thus making them potentially useful for electrochemical devices.

低湿度下限制在UiO-67膜中的离子液体的增强的离子电导率

在这项研究中,成功​​地合成了一种新型的导电MOF /聚合物杂化物。首先将[BMIM] BF 4离子液体掺入UiO-67中,然后通过将[BMIM] BF 4 @ UiO-67掺入聚丙烯腈(PAN)基质中来制备复合膜。[BMIM] BF 4 @ UiO-67 / PAN膜在低湿度下显示出增强的离子电导率(当[BMIM] BF 4 @ UiO-67含量为60 wt%时,在90°C下为2.53×10 -4 Scm -1)条件(相对湿度35%),因此使其有可能用于电化学装置。
