Abstract
The PTMSP[Poly(1-trimethylsilyl-1-propyne)]-NaY zeolite composite membranes were prepared by adding 0~50 wt% NaY zeolite to PTMSP. In order to investigate the characteristics of these membranes, we used the analytical methods such as FT-IR, $^1H$-NMR, GPC, DSC, TGA, and SEM. Gas permeation experiments were carried out at $23{\sim}26^{\circ}C$, $2kgf/cm^2$, and the permselectivity of $H_2$ and $N_2$ gases through the composite membranes was studied as a function of the NaY zeolite contents. According to TGA measurements, when NaY zeolite was inserted within the PTMSP, thermal stability of PTMSP was enhanced. Based on SEM observation, NaY zeolite was dispersed in the PTMSP-NaY zeolite composite membrane with a size of $1.5{\mu}m$. The permeability of $H_2$ and $N_2$ through the PTMSP-NaY zeolite composite membranes increased as NaY zeolite content increased. On the contrary, the selectivity($H_2/N_2$) of the PTMSP-NaY zeolite composite membranes decreased as zeolite content increased.
