Gas permeation through a synthesized composite PDMS/PES membrane
Abstract(#br)In this paper, a defect-free polydimethylsiloxane (PDMS)-based composite membrane was synthesized and characterized. The membrane consisted of a thin PDMS film (4\u003cce:hsp sp=\"0.25\"/\u003eμm) and polyethersulfone (PES) as a support material. At first, a macroporous PES support was prepared by phase inversion method and its thickness, porosity, pore size distribution and surface porosity were determined. PES characterization results confirmed suitability of the support for the composite membrane preparation.
