초록

고정 산소 운반체로 [N, N'-bis (3-(salicyldeneamino) propyl) amine Co(Ⅱ)를 함유하는 polydimethylsiloxane(PDMS-Co(saldpt))을 poly[dimethyl(chloromethylphenethyl) methylsiloxane]으로 부터 합성하였다. Co(saldpt)는 산소 분자와 선택적, 가역적으로 반응하는 것을 UV-visible spectrum으로 확인하였다. Time lag법으로 기체의 투과도와 확산도를 측정하였으며, upstream압력이 감소함에 따라 산소의 투과도와 확산도는 증가하는 반면에 용해도는 거의 일정한 경향을 보였다. 또한 1wt%의 Co(saldpt)를 함유하는 PDMS막에서는 40℃, 25mmHG에서 투과도 18.6barrer, 선택도 4의 결과를 보여 산소가 촉진 수송되는 것을 확인하였고 이를 dual sorption의 개념으로 설명하였다.

Polydimethylsiloxane(PDMS) containing [N, N'-bis (3- (salicylidene amino) propyl) amine Co(Ⅱ)] (Co(saldpt)) as a fixed oxygen carrier was synthesized. UV-visible spectra of the membrane demonstrated that Co(saldpt) binded molecular oxygen specificaaly and reversibly. From time lag method experiment, it was found that both oxygen permeability and diffusibity increase with decreasing upstream pressure, while solubility maintain nearly constant. The maximum oxygen permeability and oxygen selectivity over nitrogen obtained was 18.6 barrer and 4, respectively, at 25mmHg and 40℃ from the the PDMS membrane containing 1 wt% of Co(saldpt). Facilitation behavior was explained in terms of the dual sorption model.
