Abstract: Polytrimethylsilylpropyne(PTMSP)ultrathin composite membrane has been prepared. The effects of the morphology and structure of the support membrane on gas permeation of the composite membrane has been studied. The relationship between the relative molecular mass of PTMSP and permeability of the membrane are discussed, and the effects of the membrane forming process on its gas permeation property has been examined.

Key words: polytrimethylsilylpropyne, ultrathin composite membrane, preparation, oxygen nitrogen permeation
