Surface Modification by Fluorine and Oxygen-Nitrogen Permeability of Poiy[1-(trimethylsilyl)-1-propyne]
Abstract:
Poly[1-(trimethylsilyl)-1-propyne]membranes were modified with fluorine gas.The fluorinated membranes exhibited good gas permeation properties and a significant increase in gas selectivity over the unfluorinated PTMSP membranes.The oxygen-nitrogen separation coefficient αO2/N2 increased from 1.5 to 4.75,the oxygen permeation PO2 coefficients decreased from 8600 to 370 barrier,and the constancy of gas permeabitily of the membranes was improved.
