Abstract

Celgard 및 Durapore 막을 플라즈마로 처리하여 막의 소수성 및 아민용액에 대한 저항성을 조사하였다. 플라즈마 기체(또는 증기)로는 CF4, Hexafluorobenzene(HFP), Pentafluoropyridine(PFP) 그리고 Hexamethyldisiloxane(HMDS)를 사용하였다. 플라즈마로 처리시킨 막의 표면구조는 FT-IR 스펙트럼을 이용하여 분석하였다. 플라즈마로 처리시킨 막의 물에 대한 접촉각은 플라즈마 기체의 종류에 따라 다른 특성을 나타내었다. Celgard와 Durapore 모두 HFB이나 PFP의 플라즈마로 처리하였을 경우에는 접촉각이 감소하였으나, CF4 또는 HMDS의 플라즈마로 처리하였을 경우에는 플라즈마로 처리하지 않은 경우보다 접촉각이 증가하였다. Monoethanolamine(MEA)용액에 대한 저항성은 Celgard의 경우에는 플라즈마로 처리하였을 경우가 순수한 Celgard보다 낮았으나, Durapore는 CF4 플라즈마로 처리하였을 경우 MEA에 대한 저항성이 증대되었다.

Celgard and Durapore membranes were plasma-treated to enhance the hydrophobicity and durability to amine solution. The plasma gases or vapors used were CF4, Hexafluorobenzene(HFP), Pentafluoropyridine(PFP) and Hexamethyldisiloxane(HMDS). The surface structure of plasma treated membranes was analyzed by FT-IR spectra. The contact angles of plasma treated Celgard and Durapore were dependent of the plasma gases used. CF4 and HMDS plasma increased the contact angles of Celgard and Durapore, while HFB and PFP plasma decreased the contact angles. Durability to monoethanolamine(MEA) solution was enhanced for CF4 plasma-treated Durapore, while the durability was not good for plasma-treated Celgard.
