| Abstract: | Polydimethylsiloxane(PDMS-AMEO) / organic montmorillonite(OMMT)/polyether sulfone(PES) composite membranes were prepared by in situ anionic polymerization using aminopropyltrimethoxy(AMEO) as cross-linker.The morphology,thermal properties and interaction of PDMS-AMEO/OMMT/PES membranes were characterized by scanning electron microscope(SEM) and thermal gravimetric analysis(TGA).The swelling properties of blend membranes in acetic acid aqueous solution,and the effect of OMMT content,feed temperature and conc... |
