[0025] Filter membrane 12 is a high molecular polymer membrane, and common ones include polydimethylsiloxane (PDMS), polyimide (PI) and cellulose acetate (CA) etc. PDMS membrane has good gas permeability and selectivity, and the flexible structure of its molecular chain enables small molecule gases such as oxygen to diffuse relatively easily in the membrane.
