Organic/inorganic composite membrane is a new research topic in the membrane technology.In this study

the method of polymerization pyrolysis was adopted to modify the substrate and dip coating was used to prepare polymer/ceramic composite membrane.The effects of various factors on the process of membrane preparation were studied by orthogonal design.The selectivities of oxygen to nitrogen in both silicone rubber/ceramic and PPESK/ceramic composite membranes prepared are tantamount to intrinsic selectivities of the corresponding pure polymers separately

showing that the defect free polymer/ceramic composite membranes were successfully synthesized.The composite membranes possess good thermostability

which could lead to commercialization in both gas separation and membrane reaction at a relatively higher temperature.
