AFM을 이용한 폴리술폰막의 표면구조와 상분리현상에 관한 연구
Surface structure and phase separation mechanism of polysulfone membranes by AFM
초록
Asymmetric polymeric membranes prepared by the phase transition technique usually have either a top layer consisting of closely packed nodules or pores dispersed throughout the membrane surfaces. In this study, we present AFM image of a polysulfone membrane which show a clear evidence for the nodular structure and porous structure resulted from different phase separation mechanisms; spinodal decomposition and nucleation and growth. The surface morphology obtained by SEM and AFM was also compared.
