초록
PTMSP/PDMS-PEI 복합막을 제조하고, 막의 특성을 FT-IR, $^1$H-NMR, DSC, TGA, GPC, SEM을 사용하여 조사하였다. 제조된 PTMSP/PDMS copolymer의 수평균분자량((equation omitted))은 501,516이었고, 중량평균분자량((equation omitted))은 675,560이었다. 제조된 고분자 복합막에 의한 $H_2$/$N_2$ 혼합기체분리는 $25^{\circ}C$에서 압력의 변화에 따라 조사하였다. PTMSP/PDMS-PEI 복합막들의 수소에 대한 분리인자($\alpha$, $\beta$, (equation omitted)) 값은 투과셀의 압력이 증가하면 증가하였다. PTMSP/PDMS-PEI 복합막의 수소에 대한 $\alpha$, $\beta$, (equation omitted) 값은 $\Delta$P 345.55 kPa와 $25^{\circ}C$에서 각각 21.50, 49.14, 1.84이었다.
PTMSP/PDMS-PEI composite membrane was prepared by solution casting method. To investigate the characteristics of this membrane, the analytical methods such as FT-IR, $^1$H-NMR, DSC, TGA, GPC, and SEM have been utilized. The number-average((equation omitted)) and weight-average((equation omitted)) molecular weight of PTMSP/PDMS copolymer were 501,516 and 675,560 respectively. The separation of the gas mixture($H_2$/$N_2$) through the composite membrane was studied as a function of pressure. The separation factor($\alpha$, $\beta$, (equation omitted)) of the composite membrane used in this work increased as the pressure of permeation cell increased. The real separation factor($\alpha$), head separation factor($\beta$), and tail separation factor ((equation omitted)) of PTMSP/PDMS-PEI composite membrane were 21.50, 49.14 and 1.84 respectively at $\Delta$P 345.55 kPa and $25^{\circ}C$.
