以YSZ粉末、聚醚砜(PES)、N,N-二甲基吡咯烷酮(NMP)为原料,聚乙烯吡咯烷酮(PVP)为添加剂,NMP与水的混合溶液为芯液,自来水为外凝固液,利用相转化法制备了中空纤维陶瓷膜,并研究了PVP质量、芯液组成、涂膜次数对中空纤维陶瓷膜结构和性能的影响.结果表明:随着PVP质量的增加,中空纤维陶瓷膜的抗弯强度逐渐增加,孔隙率与水通量逐渐减小;随着芯液中NMP质量分数的减小,膜的抗弯强度逐渐增强,其水通量和透气率逐渐减小,膜的管壁逐渐变厚;随着涂膜次数的增加,中空纤维陶瓷膜的抗弯强度随之增大,透气率随之减小,修饰层逐渐变厚,膜外表面的孔径和孔数逐渐减少,膜外表面变得越来越致密.“,”The hollow fiber ceramics membranes is prepared by phase inversion method,using YSZ powder,polyether sulphone (PES) and N,N-2-methyl-pyrrolidone (NMP) as raw materials,polyvinyl pyrrolidone (PVP) as additive,mixed solution of NMP and water as the inside coagulant and running water as external coagulant.The influences of the mass of PVP,the composition of inside coagulant and the number of immersion on the structure and properties of the hollow fiber ceramics membranes are investigated.The results show that with the increase of the mass fraction of PVP,the mechanical strength of membranes is increased,but the porosity and water flux of membranes are decreased.When the mass fraction of NMP in inside coagulant is decreased,the mechanical strength of membranes is increased,but the air permeability and water flux of membranes are decreased and the tubewall of membranes becomes thicker.With the increase of the dipping times,the mechanical strength,the air permeability and thickness of membranes show the same trends with that of decreasing NMP.The diameter and the number of the pores of the outer surface of membranes are decreased and the outer surface of membranes becomes more and more dense.
