The structuring of the metal-organic framework material ZIF-8 as films and membranes through the vapor-phase conversion of ZnO fractal nanoparticle networks is reported. The extrinsic porosity of the resulting materials can be tuned from 4% to 66%, and the film thickness can be controlled from 80 nm to 0.23 mm, for areas >100 cm. Freestanding and pure metal-organic frameworks (MOF) membranes prepared this way are showcased as separators that minimize capacity fading in model Li-S batteries.
据报道，通过氧化锌分形纳米颗粒网络的气相转化，将金属有机框架材料ZIF-8构建成薄膜和膜。对于面积大于100平方厘米的材料，所得材料的外在孔隙率可在4%至66%之间调节，膜厚度可控制在80纳米至0.23毫米之间。以这种方式制备的独立式纯金属有机框架（MOF）膜被展示为可使模型锂硫电池容量衰减最小化的隔膜。
