| 摘 要： | 采用有机相转化与固态粒子烧结法相结合,通过一步成型制备了非对称多孔氧化钇稳定氧化锆(YSZ)中空纤维陶瓷膜。SEM微观结构分析表明,制备的YSZ中空纤维陶瓷膜为非对称多孔结构,中间为多孔海绵状结构,内外两侧为指孔结构,且内外表层平均孔径分别为0.43μm和0.18μm。YSZ中空纤维陶瓷膜抗弯强度和纯净水通量分别为210.5MPa和4.02m~3·m~(-2)·h~(-1)·bar~(-1)。

| Abstract: | Yttria-stabilized zirconia(YSZ) hollow fiber membranes which have an asymmetric structure have been developed in one step by a combined phase inversion and sintering technique,based on a dry/wet spinning process.Microstructure observation show that the prepared hollow fibers have the asymmetric structure including the sponge-like structures at center,sandwiched by the long finger-like structures located at the outer and inner walls of the fibers.The mean pore size of the inner and outer skin layers was 0.43... |
