In this study, we focused on acetylated–cyclodextrins (AcCD) as a microporous material to improve the performance of cellulose acetate (CA) membrane. Separation membranes, CA/AcCD, were prepared by adding AcCD to CA up to 50 wt%. Permeability coefficients (P) and ideal separation factor of CA/AcCD were determined by the vacuum time-lag method at 2 atm and 35 ℃ for He, H2, O2, N2, CH4 and CO2 gases. CA/AcCD was obtained as a transparent membrane with a thickness of 14 ～ 47 μm. Permeability coefficients of CA/AcCD was high compared to CA membrane, especially for methane having the largest kinetic diameter among the measured gases. Gas permeability was investigated using AcCD closed the pores with molecular inclusion, and it was found that the gas did not permeate the micropore of CD contained in the membrane. Thus, it was considered that the increase in the P values by the addition of AcCD was caused by the increase in the diffusivity coefficients due to the expansion of the gap between the polymer chains.
