Abstract Asymmetric porous SiOC membranes with different pore characteristic and membrane morphology were produced for the first time by adapting the phase inversion tape casting technique to the polymer-derived ceramic route. Polymethyl siloxane (MK) was used as a ceramic precursor. The produced tapes were pyrolyzed under N2 atmosphere. The structure and surface characteristics were tailored by changing the pyrolysis temperatures (600 and 1000 °C), polyvinylpyrrolidone and solid loading. Scanning electron microscopy analysis revealed the asymmetric morphology composed by a thin skin-layer (average pore size

通过相转化流延工艺生产的非对称聚硅氧烷基SiOC膜

摘要 将相转化流延技术应用于聚合物衍生陶瓷路线，首次制备了具有不同孔特征和膜形貌的非对称多孔SiOC膜。聚甲基硅氧烷 (MK) 用作陶瓷前体。生产的胶带在 N2 气氛下热解。通过改变热解温度（600 和 1000 °C）、聚乙烯吡咯烷酮和固体负载量来调整结构和表面特性。扫描电子显微镜分析揭示了由薄皮层（平均孔径大小）组成的不对称形态
